Description

  The present invention can perform various skin treatments by selectively irradiating a human epidermis with a predetermined pattern of light emitted from a light source capable of emitting light in a plurality of wavelength regions. The present invention relates to a skin beautifying device.

  Conventionally, it has been confirmed that the color has a psychological effect and a physiological effect on the human body. For example, purple has an effect of promoting circulation function that raises blood pressure and heart rate and suppresses appetite, and blue has an effect of suppressing physical activity and calming the mind. In addition, green has a sedative effect, yellow has an effect of enhancing the function of the digestive system and alleviating mental tension, and red has an effect of increasing heart rate and promoting metabolism. There is an effect such as warming up. In addition, as a direct action on the epidermis, for example, blue, white, and green are easily absorbed by oxyhemoglobin, and have the effect of improving red bruise and redness. In addition, yellow, orange and red are easily absorbed by melanin and have an effect of promoting the improvement of spots. Furthermore, light in the infrared region is easily absorbed by moisture, and has effects such as improvement of wrinkles and increase in collagen.

  A health device that relieves pain in an affected area by utilizing the action of light having a predetermined wavelength region on the human body is disclosed (for example, see Patent Document 1). In this health appliance, a user selects a predetermined light emitting diode lamp according to a required treatment effect from a plurality of light emitting diode lamps emitting different colors, and the selected light emitting diode lamp is incorporated into the health appliance. It was to be used in.

  As a skin treatment, vitamins were applied to the skin to give nutrition, but even if an ionic substance tried to penetrate the skin, negative ions were adsorbed by the stratum corneum and positive ions permeated through the stratum corneum. Although it was able to be adsorbed after that, it could not penetrate further into the deep part of the skin. Therefore, simply applying it had a low absorption efficiency from the skin, and it could not penetrate into the dermis.

  This is because it is weakly acidic due to the presence of many protons in the stratum corneum of human skin, and weakly alkaline because of the presence of many anions and hydroxide ions in the granule layer. This is because a barrier zone in which a film is electrically stretched between the stratum corneum and the granule layer is formed, and this acts to suppress entry of foreign matter.

  On the other hand, as a method for promoting percutaneous absorption of water-soluble vitamins, it has been found useful to use an iontophoresis method, and various facial and skin beautifiers using the iontophoresis method have been considered ( For example, see Patent Document 2.)

In this iontophoresis method, an electrode is brought into contact with the skin and a weak current is applied to weaken the function of the barrier zone, and further, the electrical property between the ionic substance (for example, water-soluble vitamin C) to be permeated and the electrode. The substance penetrates into the skin by the repulsive force.

  However, in the health device using the above-described conventional light emitting diode lamp, the user selects a diode lamp according to an action required from a plurality of light emitting diode lamps that emit different colors, and further selects the selected diode lamp. There is a problem that it takes time and effort for the user because the light-emitting diode lamp must be used by being incorporated into a health appliance.

  Furthermore, with this apparatus, it has been impossible to synergistically obtain the treatment effect of each color by simultaneously irradiating the human body with light of different colors.

  Moreover, the skin beautifier using the iontophoresis method can only penetrate the skin with a water-soluble substance that is likely to exist as ions, and the fat-soluble substance has little effect. In addition, since the iontophoresis is performed by directly or indirectly bringing the electrode into contact with the skin and supplying electricity to the human body, there are cases in which an abnormality such as a rash, redness, or itchiness is felt on the skin.

  Therefore, there has been a demand for an apparatus that can penetrate even a fat-soluble substance into the skin, promotes the penetration of vitamins and the like that are less likely to cause abnormalities in the skin and are easy to handle.

  Therefore, the present invention can selectively irradiate the human body with light in different wavelength regions, and the effect of the epidermis by the color of the irradiated light and the penetration of the drug applied to the epidermis into the skin are enhanced. An object is to provide a skin beautifying apparatus capable of performing a treatment.

  In order to achieve the above object, the skin beautifying device of the present invention has a plurality of light sources that emit light of a specific wavelength region, and the light sources emit at least two types of hues by emitting light of different wavelength regions. A light irradiation mechanism, a power source that supplies power to the light source, and a pattern switching unit that can turn on the light source in a plurality of patterns by controlling the power supplied to the light source. To do.

  According to the skin beautifying apparatus of the present invention, light having a predetermined wavelength region that gives a treatment effect can be irradiated to the epidermis of a human body by a light emitting diode lamp, and a predetermined wavelength that gives an effect of promoting the penetration of vitamins into the skin. Since the light of the region can be easily radiated to the skin to be penetrated, it is required for the skin by selecting the optimum state by selectively irradiating the light of the predetermined wavelength region. You can do treatments.

  Hereinafter, the present invention will be described in detail.

Each of the first light source region and the second light source region includes a plurality of light sources, and the light sources include, for example, a light emitting diode lamp (light emitting diode lamp). The first light source region is provided with a plurality of light emitting diode lamps that emit light having a wider wavelength region than the second light source region or a wider wavelength region as a whole. In addition, this skin beautifying device controls the power supplied from the power source for each light source region, and also controls the emission of light by forming a pattern that combines light of a predetermined wavelength region and the emission pattern in terms of time. Pattern switching means for switching the light emission pattern of the light emitting diode lamp by performing control such as changing is provided.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view of a skin beautifying apparatus according to a first embodiment of the present invention, FIG. 2 is a side view of the skin beautifying apparatus, and FIG. 3 is a functional block diagram showing a control system of the skin beautifying apparatus.

  As shown in these drawings, the skin beautifying device 10 in the present embodiment has a first light source region 11 that emits yellow light and a second light source region 12 that emits light of a different color. This is a handy type (portable) skin-beautifying device.

  The skin beautifying device 10 has an outer shell formed by a base casing 14 provided with a grip 13 that is gripped by a user. This base housing | casing part 14 has a form which crushed the cylinder to the radial direction so that predetermined thickness might be given, for example. The grip portion 13 is formed on one end side of the base housing portion 14. Furthermore, the other end portion of the base housing portion 14 protrudes from the central portion of the front surface (front surface) of the base housing portion 14, and the first light source region 11 and the second light source region 12 are installed on the surface thereof. A light source installation portion 15 having a truncated cone shape or a cylindrical shape is provided. In addition, the cross-sectional shape parallel to the front surface of the base housing portion 14 of the protruding light source installation portion 15 is not limited to such a circle, and may be a rectangle, a polygon, or the like.

  A protective cap 16 is provided on the surface of the light source installation unit 15, and, for example, the skin of a human body contacts the first light source region 11 and the second light source region 12 provided in the light source installation unit 15. Is preventing. A contact cap 17 made of a transparent or translucent light transmissive member having a truncated cone shape that comes into contact with the human skin when light is irradiated is detachably fitted to the side wall of the light source installation portion 15. ing. The contact cap 17 may be attached to the side wall of the light source installation unit 15 by screwing. Note that the protective cap 16 and the contact cap 17 are made of a material having a high light transmittance, and those having particularly remarkable absorption characteristics in a predetermined wavelength region are not preferable.

  In order to adjust the distance L between the first light source region 11 and the second light source region 12 and the skin of the human body irradiated with the light emitted from the first light source region 11 through the contact cap 17, the height of the truncated cone shape is adjusted. It is preferable that a plurality of contact caps 17 having different sizes are prepared. The user can appropriately select the spare contact cap 17 and fit the selected contact cap 17 to the side wall of the light source installation unit 15 to irradiate light.

  By changing the distance L between the light source region 12 and the human skin with the contact cap 17, the irradiation area of the light emitted from the light source region 12 onto the skin can be changed. For example, when the irradiation is performed with the distance L being reduced, the treatment can be performed by narrowing down the irradiation area. A wide area is irradiated with light, and a wide area treatment can be performed. At this time, since the irradiation intensity also changes, it can be used to adjust the intensity suitable for promoting penetration.

  Further, the contact cap 17 may be made of a material that does not transmit light around it and can transmit light only in the central portion. In this case, light irradiation is performed in a spot on a smaller area. Treatment can be performed only on necessary parts.

  In addition, a power button 18 for turning on / off the main power source and a mode switching button 19 for switching the light irradiation pattern mode are provided between the grip 13 on the front surface of the base housing unit 14 and the light source installation unit 15. It has been. The mode switching button 19 includes a mode UP button 19a and a mode DOWN button 19b. Further, in the vicinity of the power button 18 and the mode switching button 19, the power source 20 that switches the display color and lighting state according to the input operation from the power button 18, and the input according to the input operation from the mode switching button 19. A mode display light source 21 for switching the display color and lighting state is provided.

  Here, when the mode UP button 19a is pressed while the main power is on, for example, when there are three light irradiation pattern modes, the mode is switched in the order of mode 1, mode 2, and mode 3. Instead, when the mode DOWN button 19b is pressed while the main power is on, the mode is switched in the order of mode 3, mode 2, and mode 1. The mode display light source 21 is switched in order of, for example, green lighting, orange lighting, and red lighting in response to such a mode change. Further, the correspondence relationship between the mode and the light source display may be written in advance in the vicinity of the mode display light source 21 as an operation display mark, for example. Note that if the state where the main power supply is ON and no light irradiation continues for 5 minutes continues, the power supply is automatically turned OFF, and wasteful energy consumption can be prevented.

  Further, in the vicinity of the power button 18 and the mode switching button 19, there is provided a charging display light source 22 for switching the display color and the lighting state when the charging battery provided in the base casing portion 14 is charged and when charging is completed. ing. In addition, you may comprise the electrode supply means of the skin beautifying device 10 so that a rechargeable battery or a dry cell can be used as a drive power supply, for example. Further, for example, a power input terminal portion for mounting a power output terminal such as an AC (alternating current) adapter may be provided at the edge of one end of the base housing portion 14 as power supply means.

  Furthermore, a touch sensor 23 that detects contact with the skin of the human body is provided on the side wall surface of the grip portion 13 of the base housing portion 14. The touch sensor 23 detects contact with the human skin by, for example, a hum detection method, a piezoelectric element detection method, or a strain resistance element detection method. In the skin beautifying device 10, when the touch sensor 23 does not detect contact with the human skin, for example, the first light source region 11 and the second light source region 11 are prevented from emitting light from the first light source region 11 and the second light source region 12. Measures for safety management such as controlling the two light source regions 12 are taken.

  Next, the 1st light source area | region 11 and the 2nd light source area | region 12 which are arrange | positioned at the light source installation part 15 are demonstrated with reference to FIG.

  A central portion of the light source installation unit 15 is provided with a first light source region 11 in which 20 yellow light-emitting diode lamps 101 are radially arranged substantially evenly. The second light source region 12 includes an inner peripheral light source region 12a that is disposed substantially evenly along the outer edge of the first light source region 11, and an outer periphery of the inner peripheral light source region 12a. And an outer peripheral side light source region 12b arranged substantially evenly along.

  The yellow light-emitting diode lamp 101 used for the first light source region has a peak emission wavelength at 590 nm. For example, a light-emitting diode lamp with a specification of φ3 mm can be used, but the present invention is not limited to this specification. Any light source can be used as long as it can satisfy the illuminance required as light emitted from the first light source region 11 to the skin.

  In the inner light source region 12a, a total of 15 light emitting diode lamps 102, orange light emitting diode lamps 103, yellow light emitting diode lamps 104, green light emitting diode lamps 105, and blue light emitting diode lamps 106 are arranged in this order. The light emitting diode lamp is provided. The order of arrangement of the light emitting diode lamps is not limited to this, and the light emitting diode lamps may be arranged in an order having a predetermined regularity or in an irregular order.

  The red light emitting diode lamp 102 used here is 641 nm, the orange light emitting diode lamp 103 is 609 nm, the yellow light emitting diode lamp 104 is 592 nm, the green light emitting diode lamp 105 is 522 nm, and the blue light emitting diode lamp 106 is used. Has a peak emission wavelength at 465 nm. The light emitted from each light-emitting diode lamp, in particular, the blue light-emitting diode lamp 106 that irradiates light in a wavelength region close to the ultraviolet region, does not include a light component having a wavelength in the ultraviolet region.

  Fifteen red light emitting diode lamps 107 having a peak emission wavelength in the range of 800 to 900 nm are disposed in the outer peripheral light source region 12b.

  Note that the number of light-emitting diode lamps provided is not limited to such a number, and can be set as appropriate. In addition, each light emitting diode lamp does not include, for example, light having a wavelength in the ultraviolet region that adversely affects the skin. Further, as each light emitting diode lamp used in the inner peripheral light source region 12a and the outer peripheral light source region 12b, for example, a light emitting diode lamp having a chip shape is used. Any device that can satisfy the illuminance required for the light applied to the skin from the region 11 may be used.

  In addition, the first light source region 11 is shown to include a light emitting diode lamp that emits yellow light. However, the first light source region 11 further includes red light emission having a peak emission wavelength of 800 to 900 nm. A diode lamp 107 is provided to emit light in the visible light region that does not include the wavelength in the ultraviolet region, light in the infrared region, or light that includes both the visible light region and the infrared region from the first light source region 11. You can also

  The illuminance at the time of irradiating the skin with these light sources is preferably 9000 to 30000 lux (lx), particularly preferably 13,000 to 20000 lux (lx).

  Next, the control system 30 (see FIG. 2) built in the skin beautifying apparatus 10 will be described with reference to FIG. FIG. 3 shows an outline of the configuration of the control system 30.

  A main control circuit 31 provided in the control system 30 incorporates a processor, RAM, ROM, and the like that perform overall control of the skin beautifying device 10 and various calculations. The ROM stores software such as programs and various parameters for executed control and calculation. The processor reads the software from the ROM, interprets the command statement, and executes the command using the memory space of the RAM.

  An operation content input circuit 32 is connected to the previous stage of the main control circuit 31. The operation content input circuit 32 constantly monitors the operation status of the power button 18 and the mode switching button 19, and the monitoring result is as follows. Input information corresponding to an input command from a certain user is output to the main control circuit 31.

  The main control circuit 31 includes a pattern switching unit 33 and a display control unit 34, and input information from the operation content input circuit 32 corresponding to a user input command is input to the pattern switching unit 33. The pattern switching unit 33 sets a mode based on the input information that is input, and outputs display information corresponding to the set mode to the display control unit 34. The display control unit 34 outputs control information for turning on or blinking the power source light source 20 and the mode display light source 21 in a predetermined color to the power source light source 20 and the mode display light source 21 based on the input display information. . Based on the control information, the power source light source 20 and the mode display light source 21 are turned on or blinked, and display so that the ON / OFF of the power source and the mode of the light emitting diode lamp irradiation pattern can be identified visually.

  For example, when the skin beautifying device 10 is configured using a charging battery as a power source, the display control unit 34 turns on the charging display light source 22 in a predetermined color when the charging battery is charged and when the charging is completed. Alternatively, the control information to be blinked is output to the charging display light source 22. Based on the control information, the charging display light source 22 lights up or blinks, and displays the charging state of the power supply so that it can be visually identified.

  Further, the control system 30 includes a first light source light emitting circuit 35 and a second light source light emitting circuit 36 connected to the pattern switching unit 33. The pattern switching unit 33 controls the first light source light emitting circuit 35 and the second light source light emitting circuit 36 based on the operation information input from the operation content input circuit 32.

  The first light source light emitting circuit 35 is a circuit that controls the first light source region 11 disposed in the central portion of the light source installation unit 15, and includes 20 yellow light sources disposed in the first light source region 11. This is a circuit for controlling the light emitting diode lamp 101. That is, it is determined whether or not the light emitting diode lamp 101 included in the first light source region 11 is caused to emit light.

  The second light source light emitting circuit 36 has an inner peripheral side light source region 12a disposed substantially evenly along the outer side of the outer edge of the first light source region 11, and an outer side of the outer edge of the inner peripheral side light source region 12a. This is a circuit for controlling the outer peripheral side light source region 12b that is arranged substantially evenly. The second light source light emitting circuit 36 controls the light emitting diode lamp provided in the inner peripheral light source region 12a for each light emitting diode lamp or for each color, and the red light emitting diode lamp provided in the outer peripheral light source region 12b. This is a circuit for controlling 107 for each light emitting diode lamp or collectively. Further, as shown in FIG. 1, the second light source region 12 has an array configuration divided into three blocks along the outer edge of the first light source region 11, and is controlled for each block. In this manner, the second light source light emitting circuit 36 can be configured.

  In addition, a touch sensor circuit 37 is connected to the front stage of the main control circuit 31, and the touch sensor circuit 37 constantly monitors contact information from the touch sensor 23, and a user who is a result of the monitoring is monitored. Contact information corresponding to touching the touch sensor 23 is output to the main control circuit 31. When the contact information is output from the touch sensor circuit 35 to the main control circuit 31, the control that enables information transmission between the first light source light emitting circuit 35 and the second light source light emitting circuit 36 and the pattern switching unit 33 is performed. Thus, light can be emitted from the first light source region 11 and the second light source region 12. On the other hand, when contact information is not output from the touch sensor circuit 35 to the main control circuit 31, information transmission between the first light source light emitting circuit 35 and the second light source light emitting circuit 36 and the pattern switching unit 33 is cut off. In this state, light cannot be emitted from the first light source region 11 and the second light source region 12.

  Next, an operation for performing skin treatment using the skin beautifying apparatus 10 will be described.

  The user first presses the power button 18 to turn on the power. Subsequently, an arbitrary mode is selected from preset modes by the mode switching button 19, and the contact cap 17 is brought into contact with the skin to be treated to irradiate light.

  Here, a case where three modes, mode 1, mode 2, and mode 3, are set as an example of preset light emission pattern modes will be described.

  In mode 1, all the light emitting diode lamps arranged in the first light source region 11 and the second light source region 12 are turned on, and the first light source region 11 and the second light source region are connected via the contact cap 17. The light of all the colors 12 is applied to the skin. The illuminance at this time is 20000 lux (lx). In this mode 1, it is possible to irradiate the skin with light in the entire wavelength region of visible light at a time.

  The skin beautifying device 10 of the present invention can obtain light with sufficient illuminance of 20000 lux (lx) even when the power consumption is as small as 5 W, and enables operation with energy saving.

  In mode 2, all the light emitting diode lamps arranged in the first light source region 11 are turned on, and yellow light is irradiated to the skin through the contact cap 17. In this mode, the light source region is set so that the illuminance emitted from the first light source region 11 is larger than the illuminance of the light emitted from the second light source region 12, so that treatment with high output light is performed. It can be carried out.

  In mode 3, all the light emitting diode lamps arranged in the second light source region 12 are turned on, and through the contact cap 17, yellow, orange, red light in the wavelength region of 570 to 780 nm and 430 to 570 nm Blue and green light in the wavelength region is irradiated on the skin.

  According to the skin beautifying device 10 of the present invention, the skin can be irradiated with light of one or a plurality of different wavelength regions from a light emitting diode lamp, and skin penetration is effectively promoted for the target vitamin or provitamin. The effect can be obtained. Furthermore, skin treatment can be performed by the chromotherapy effect of color on the skin. At this time, optimal light irradiation can be performed in order to obtain a desired effect by selectively switching the light patterns in the plurality of different wavelength regions.

  Here, the function and operation of the light-emitting diode lamp used in these three modes will be described with reference to the light absorption characteristics shown in FIG.

  That is, the light emitted from the light emitting diode lamps 102 and 107 (red) has, for example, a peak wavelength of 641 nm and a luminous intensity of 600 mcd. This red light has a high skin penetration rate, reacts to melanin in the deep part of the skin, and is effective in removing spots deep in the skin. Also, combined with red color action, it is suitable for improving reddish skin, and blood circulation promoting effects can be obtained. It is also suitable for so-called slimming care.

  The light emitted from the light emitting diode lamp 103 (orange) has, for example, a peak wavelength of 609 nm and a luminous intensity of 200 mcd. This orange light is absorbed by melanin / hemoglobin and is effective in removing brown spots. Further, the effect of color is important for improving oily skin or acne skin and for optimizing metabolic function.

  Furthermore, the light emitted from the light-emitting diode lamps 101 and 104 (yellow) has, for example, peak wavelengths of 590 and 592 nm, and luminous intensity of 3000 and 220 mcd, respectively. This yellow light has a higher skin penetration rate than the light emitted from the light emitting diode lamp 102 (red) or the light emitted from the light emitting diode lamp 103 (orange), and is therefore effective in removing spots on the skin surface. Moreover, it is suitable for the improvement of aging skin and trouble skin as a function of color.

  The light emitted from the light emitting diode lamp 105 (green) has a peak wavelength of 522 nm and a luminous intensity of 140 to 560 mcd, for example. This green light has a higher skin penetration than a light-emitting diode lamp 106 (blue), which will be described later, and is absorbed by hemoglobin in the deep dermis and is effective for red aza in the deep dermis. The effect of color is suitable for improving dry skin and removing spots due to sebum and pigmentation. In addition, the body and mind can be relaxed.

  The light emitted from the light-emitting diode lamp 106 (blue) has, for example, a peak wavelength of 465 nm and a luminous intensity of 70 to 200 mcd. Since this blue light is well absorbed by hemoglobin, it is effective for red face and red aza. As an effect of color, it increases lymph drainage action and blood circulation action. Furthermore, the effect etc. which relieve stress and tension can be acquired.

  That is, as shown in FIG. 4, as an effect due to the difference in the wavelength region, blue and green (465 to 522 nm) are absorbed by hemoglobin, and it is possible to improve the red aza and reddish face.

  Here, the action of light in this wavelength region will be described in detail. The light in this wavelength region is absorbed by hemoglobin and induces a mild vascular wall injury. This causes fibroblasts to collect and produce collagen to heal the wound. By increasing the amount of collagen, beautiful skin is created naturally from the inside, and the skin becomes firm and shiny. Further, yellow, orange and red (465 to 522 nm) are absorbed by melanin, and can promote whitening and promote whitening by transpiration at the pigment site.

  Furthermore, the present invention may be configured to emit infrared rays, and for example, can be easily configured by replacing the light emitting diode lamp 107 with one that emits infrared rays. Infrared rays (870, 940 nm) have good permeability and are absorbed by moisture, can activate the deep part of the skin, improve wrinkles and increase collagen. Here, the action of infrared rays will be described in detail. When infrared rays are applied to the skin, the infrared rays are absorbed by moisture (60 to 70% of the dermis is moisture) in the deep dermis (for example, a site about 10 mm from the epidermis). As a result, the water molecules vibrate, generate heat, slightly warm the deep dermis, and activate the fibroblasts that produce collagen and elastin.

  Therefore, according to the skin beautifying device 10 of the present invention, the hue of light applied to the skin surface can be changed at a predetermined time interval, so that a plurality of types of effects obtained from individual lights having different wavelengths can be continuously obtained with a simple operation. Can be applied to the skin surface efficiently, and beautiful skin treatment can be performed efficiently.

  Since this skin beautifying device 10 has a handy type structure, the user can arbitrarily select an area of the skin and easily irradiate the light of the light-emitting diode lamp on the area.

  Further, the skin beautifying device 10 uses a light emitting diode lamp as a light source, and in this case, power consumption can be reduced. For example, when a mounting power source such as a dry battery or a charging battery is used, the skin beautifying device 10 is used for a long time. Can be operated.

  The skin beautifying device 10 can also be used to promote the penetration of vitamins and the like into the skin. At this time, the penetration of vitamins and the like does not cause electricity to flow directly to the human body and causes little irritation to the skin. Therefore, the burden on the skin can be reduced as compared with the case where vitamins are permeated by iontophoresis.

  In addition, although light irradiation is performed to the skin which apply | coated the skin external preparations, such as a solution containing a vitamin or a provitamin, etc., as a vitamin of this invention, vitamin A, B group, C, D, E, Well-known vitamins such as F, H, and K are included, and among these, fat-soluble vitamins such as vitamins A, D, E, and K are preferable, and vitamin E such as tocopherol and tocotrienol is preferable. Is more preferable. The term vitamin used in the present invention includes its analogs and derivatives.

  The provitamin of the present invention can be used without particular limitation as long as it is a precursor of these vitamins, and the provitamin is a fat-soluble provitamin such as ferrol acetate or fat-soluble provitamin C. It is preferable that

  This permeation promotion is achieved by creating an instantaneous channel (channeling) in the cement substance (collagen, elastin, filaggrin, etc.) between skin cells by light irradiation using the skin beautifying device of the present invention. This is considered to be because the light penetrates easily. The depth of the light reaching the skin differs depending on the wavelength of the light. The longer the wavelength, the greater the degree of reach of the skin.

  Moreover, it was confirmed by light irradiation using the skin beautifying device of the present invention that both fat-soluble provitamin C and water-soluble provitamin C can promote penetration into the skin. By promoting penetration, vitamin C can be supplied to the epidermis and dermis, and effects such as wrinkle protection, stain protection, and whitening can be effectively obtained.

  However, when vitamin C is directly supplied to the skin to supply vitamin C, the time during which vitamin C, which is a characteristic that is easily oxidatively decomposed, is present in the skin is limited, and its effect is also limited. . Therefore, by supplying provitamin C, after permeation into the skin, the vitamin C converting enzyme in the skin gradually converts provitamin C to vitamin C to continuously convert vitamin C. Supplying is preferable in that the treatment effect can be effectively exhibited.

The mechanism of conversion of provitamin C into vitamin C at this time is considered as follows.
The internal pigment chromophore present in the epidermis absorbs the light by light irradiation, and an instantaneous excitation state is established, and the vicinity of the chromophore is instantaneously heated. At this time, a conversion enzyme that converts provitamin C, which is presumed to exist as a cell stroma or a cell membrane-bound type of the epidermis, is activated, and provitamin C permeated from the epidermis is converted to vitamin C. The Furthermore, provitamin C and vitamin C will penetrate deeper into the skin due to cracks generated between cells due to light irradiation.

  Therefore, the present invention capable of simultaneously accelerating the penetration of provitamin C and activating the conversion of provitamin C to vitamin C by light irradiation is particularly excellent as a method for supplying vitamin C into the skin. Is.

  In consideration of the depth of light arrival and the effect of promoting penetration of vitamins and the like, the wavelength of light applied to the skin is preferably 560 to 640 nm, and particularly preferably about 560 nm. At this wavelength, conversion of provitamin C to vitamin C is also promoted, which is extremely effective for skin treatment.

  In the skin beautifying device 10 of the present embodiment, the skin surface is irradiated with light using a light-emitting diode lamp.

Further, for example, a power input terminal portion for mounting a power output terminal such as an AC (alternating current) adapter may be provided at the edge of one end of the base housing portion 52 as power supply means.

  Furthermore, a pair of gripping electrodes 61 and 62 that function as contactors of the touch sensor are provided on the side wall surface of the gripping portion 51 of the base casing 52. Here, in a state where the user holds the grip portion 51 of the skin beautifying device 50, the grip electrodes 61 and 62 come into contact with each finger and palm of the user. That is, the touch sensor circuit 70 is connected to the gripping electrodes 61 and 62. The touch sensor circuit 70 generates, for example, a weak alternating voltage generated when the grip electrodes 61 and 62 are in contact with the skin so that it can be determined whether or not the user's skin is in contact with the grip electrodes 61 and 62. It is a circuit to detect. In addition to the contact type, the touch sensor circuit 70 may be one that detects a change in impedance such as capacitance or resistance, or one that detects a change in pressure using a piezoelectric element.

The above measures are taken.

  As shown in FIG. 7, the head unit 53 includes an ultrasonic vibrator 63 made of piezoelectric ceramic or the like, and the ultrasonic wave generation circuit 64 is connected to the ultrasonic vibrator 63 at a high frequency alternating current when driven. Power is supplied to vibrate the head unit 53. At this time, as the ultrasonic vibration, for example, a frequency of about 0.1 to 6 MHz is preferable, and a frequency of 0.3 to 5 MHz is particularly preferable. In addition, a treatment may be performed by applying a dedicated gel to the head portion 53 so that the propagation efficiency of ultrasonic waves is increased. Here, as a constituent material of the outer portion of the head portion 53, a material made of a resilient stainless steel plate or copper plate, or a metal such as lightweight hard aluminum, titanium, duralumin, etc., and surface-treated with hard chrome plating, etc. Is exemplified.

  Further, the skin beautifying device 50 is provided with an eccentric motor 65 with respect to the head portion 53 or the base housing portion 52, and applies vibration to the head portion 53. The eccentric motor 65 is driven and controlled through a motor drive circuit 66 and vibrates the head unit 53 in a relatively low frequency band of, for example, about 80 to 100 Hz.

  Furthermore, the skin beautifying device 50 is provided with a heater 67 including a heating coil for heating the head portion 53. The heater 67 controlled to be heated by the heating circuit 68 can open pores on the skin heated through the head portion 53, and can activate the flow of blood and lymph in the skin tissue.

  Next, a control system built in the skin beautifying apparatus 50 will be described mainly based on FIG. A controller 69 provided in the control system incorporates a processor, RAM, ROM, and the like for executing overall control of the skin beautifying device 50 and various calculations. The ROM stores software for control and computation to be executed and software such as various parameters. The processor reads the software from the ROM, interprets the command statement, and executes the command using the memory space of the RAM. To do. Further, an operation content input circuit 71 is connected to the front stage of the controller 69, and this operation input circuit 71 constantly monitors the operation status of the power button 56 and the mode switching button 57, and the monitoring result. An input command from the user is notified to the controller 69.

  The controller 69 controls the operations of the light emitting diode lamp driving circuit 72, the ultrasonic wave generating circuit 64, the motor driving circuit 66, and the heating circuit 68 as described above. Here, for example, from the viewpoint of energy saving and safety, the controller 69 is in a state where a signal indicating that the skin is not in contact with the grasping electrodes 61 and 62 is input. Control is performed so as not to execute the operations of the generation circuit 64, the motor drive circuit 66, and the heating circuit 68. Here, the controller 69, the light emitting diode lamp driving circuit 72, and the light emitting diode lamps 501, 502, 503, 504, 505, 506, and 507 selectively emit light having a specific wavelength to the skin surface. Acts as a mechanism.

  Next, an operation for performing skin treatment using the skin beautifying apparatus 50 will be described.

  The user first presses the power button 56 to turn on the power. Subsequently, an arbitrary mode is selected from the preset modes by the mode switching button 57a, and light is emitted by bringing the contact cap 54 into contact with the skin to be treated.

  Here, a case where three modes, mode 1, mode 2, and mode 3, are set as an example of preset light emission pattern modes will be described.

  In mode 1, all the light emitting diode lamps arranged in the light emitting diode lamps 501, 502, 503, 504, 505, 506, and 507 are turned on, and light of all colors provided in the skin beautifying device 50 through the contact cap 54. Is irradiated to the skin. The illuminance at this time is 20000 lux (lx). In this mode 1, it is possible to irradiate the skin with light in the entire wavelength region of visible light at a time.

  The skin beautifying apparatus 50 of the present invention can obtain light with sufficient illuminance of 20000 lux (lx) even when power consumption is as small as 5 W, and enables operation with energy saving.

  In mode 2, the light-emitting diode lamp 501 is turned on, and yellow light is applied to the skin through the contact cap 54. In this mode, the illuminance emitted from the light emitting diode lamp 501 is set to be higher than the illuminance of the light emitted from the light emitting diode lamps 502, 503, 504, 505, 506, 507. Treatment can be performed with the output light.

  In mode 3, the light emitting diode lamps 502, 503, 504, 505, 506, and 507 are turned on, and through the contact cap 54, yellow, orange, and red light in the wavelength range of 570 to 780 nm and the wavelength range of 430 to 570 nm The blue and green light is irradiated on the skin.

  According to the skin beautifying apparatus 50 of the present invention, the skin can be irradiated with light of one or a plurality of different wavelength regions from a light emitting diode lamp, and skin penetration is effectively promoted for the target vitamin or provitamin. The effect can be obtained. Furthermore, skin treatment can be performed by the chromotherapy effect of color on the skin. At this time, optimal light irradiation can be performed in order to obtain a desired effect by selectively switching the light patterns in the plurality of different wavelength regions.

  The functions and operations of the light emitting diode lamp used here are as described in the first embodiment.

  Further, when the skin beautifying apparatus 50 actually performs a treatment, an operation method of moving the head portion 53 in a direction along the skin surface while bringing the head portion 53 into contact with the skin surface is exemplified.

  Here, when light of a specific wavelength and, for example, ultrasonic vibration by the ultrasonic vibrator 63 acts on the skin surface from the skin beautifying device 50, the tension of the skin muscles is loosened due to the microscopic massage effect, and spots and wrinkles are observed. The removal effect such as can be obtained. At the same time, fine bubbles can be generated on the skin, thereby removing the wastes and keratins of the skin and removing the dirt such as acne and pores. Furthermore, the ultrasonic vibration also has a drug delivery action to the skin, and can serve as an auxiliary function for more effectively promoting the penetration of vitamins or provitamins by light irradiation.

  At this time, it is known that the penetration promotion effect by ultrasonic waves increases as the frequency increases. However, since the energy density increases as the frequency increases, the cavitation phenomenon in the cell is reduced when applied to the skin. There is a possibility that the skin tissue will be crushed and the vitamin or provitamin itself that is the target of promoting penetration may be decomposed. Therefore, the ultrasonic vibration used in the present invention preferably has a frequency of 0.1 to 6 MHz so that the skin tissue and the object of penetration promotion can be prevented from being destroyed and the penetration can be promoted effectively. Particularly preferred is 0.3 to 5 MHz.

  Further, when light of a specific wavelength and low frequency vibration generated by the eccentric motor 65 act on the skin surface from the skin beautifying device 50, aquaporins on the skin surface are opened, and active ingredients such as chemicals and cosmetics are introduced into the skin. It can also be made easier. As a result, the tension of the skin is removed, the blood flow and the lymph flow are improved, and the metabolism of the skin can be increased. In order to effectively exhibit this effect, the vibration by the eccentric motor 65 is preferably a low-frequency vibration of about 80 to 100 Hz.

  That is, in the present invention, the skin whitening effect and the tissue deepening effect by selectively irradiating light in a wavelength region that constitutes the skin tissue, for example, hemoglobin, melanin, moisture, etc. The so-called chromotherapy effect (the effect of color on the skin) when irradiated with light in the visible wavelength range, the skin vitamin or provitamin penetration promotion effect by light, and the dynamic stimulation by vibration Due to the synergistic effect with the massage effect due to being applied to the skin, an excellent skin treatment effect can be obtained.

  In this invention, since the light of a specific wavelength is selectively irradiated, an effective skin beautification process can be performed by simple operation. Here, for example, by configuring the head portion with a light-transmitting material, vibration is directly transmitted to the skin surface with which the head portion is in direct contact, and light with a desired wavelength can be irradiated.

  At this time, the light irradiation mechanism has a plurality of light sources that emit light in a specific wavelength region, and each light source emits light in a different wavelength region, so that it can exhibit at least two hues. It is preferable that light applied to the skin can be appropriately selected depending on the treatment effect to be obtained.

  In the present invention, the head can be vibrated by vibration generated by an ultrasonic vibrator and / or an eccentric motor. In this configuration, when light of a specific hue and, for example, ultrasonic vibrations act on the skin surface, the muscles of the skin are loosened by the micro massage effect, and an effect of removing spots and wrinkles can be obtained. . At the same time, fine bubbles can be generated on the skin, thereby removing the wastes and keratins of the skin and removing the dirt such as acne and pores. Furthermore, the penetration of vitamins by light irradiation can be promoted by ultrasonic vibration, and the penetration promoting effect can be obtained more effectively than light irradiation alone.

  In addition, when light of a specific hue and vibration of a relatively low frequency of about 100 Hz, for example, due to an eccentric motor act on the skin surface, aquaporins on the skin surface (made of proteins that pass water on the surface of cells) For example, active ingredients such as chemicals and cosmetics can be easily introduced into the skin. As a result, the tension of the skin is removed, the blood flow and the lymph flow are improved, and the metabolism of the skin can be increased.

  Therefore, according to the skin beautifying device 50 of the present embodiment, the skin whitening effect by selectively irradiating light in a wavelength region that constitutes the skin tissue, for example, hemoglobin, melanin, moisture, etc., and the depth of the skin. Massage effect due to tissue activation effect, so-called chromotherapy effect (effect of color on skin) when irradiated with light in the visible wavelength range, and dynamic stimulation by vibration applied to skin surface By synergistic with the effect, an excellent skin treatment effect can be obtained. Moreover, in this invention, since the light of a specific wavelength is selectively irradiated, an effective skin beautification process can be performed by simple operation. In the skin beautifying apparatus 50 according to the present embodiment, the skin surface is irradiated with light using a light emitting diode lamp. Therefore, unlike the skin beautifying apparatus of the type that irradiates a laser beam having a high energy density, the skin surface is stimulated. The amount of time required for the skin to recover after treatment (down time) is short. Thereby, it is possible to perform face washing and makeup with cosmetics immediately after the treatment.

  In addition, the skin beautification treatment by the skin beautifying device 50 can be performed, for example, in the following use mode. In the following modes, the light-emitting diode lamp 507 irradiates infrared rays, and otherwise the configuration is the same as in the description of modes 1 to 3.

  Although FIG. 8 is a front view of the skin beautifying device, the skin beautifying device 80 described in these drawings shows a modification of the second embodiment, and the light emission of the skin beautifying device 50 shown in FIG. The diode lamp 501 and the head portion 53 are reversely arranged. That is, the other configurations are the same except that the light emitting diode lamp 501 is arranged in the center and the head 83 is provided in an annular shape between the light emitting diode lamp 501 and the other light emitting diode lamps. Is. The function is exactly the same as in the second embodiment.

  With such a configuration, it is possible to sufficiently secure the light amount of each light-emitting diode lamp, in particular, the light amount of the light-emitting diode lamp 501, and stably irradiate the skin with light.

(Third embodiment)
Moreover, the skin beautifying apparatus according to the third embodiment of the present invention is the skin beautifying apparatus according to the first or second embodiment, and further supplies a chemical solution or a cosmetic solution containing vitamin C as an active ingredient to the epidermis. A voltage applying means that enables the introduction of ions may be provided, and vitamin C and the like may be absorbed by the epidermis by this voltage applying means. This ion introduction means that a weak direct current (for example, 2 to 4 mA) is allowed to flow through the epidermis for about 3 to 5 minutes to break the charge balance of the epidermis, so that normally ionized chemicals or cosmetics pass through. This is a method that allows the penetration of the subcutaneous interface that cannot be penetrated. Note that the above-described direct current and the time during which the direct current is passed are not limited to this, and can be set as appropriate.

  Here, in the skin beautifying device 10 according to the first embodiment, the contact cap 17 that is brought into contact with the skin surface is used as an ion introduction electrode, and a voltage for ion introduction is applied to the contact cap 17 that is this electrode. . Here, at least a portion of the contact cap 17 that contacts the skin surface needs to have conductivity, and the contact cap 17 is, for example, a transparent or semi-metal having a metal or metal oxide film on the portion that contacts the skin surface. It is made of transparent glass, transparent or translucent conductive resin, or the like.

  Further, in the skin beautifying apparatus 50 according to the second embodiment, the head portion 53 used for vibration is made of a conductive material and used as an iontophoretic electrode.

  Hereinafter, it demonstrates based on the structure of the skin beautifying device 50. FIG.

  A skin-beautifying device according to a third embodiment of the present invention includes a conductive head part that is brought into contact with the skin surface directly or via a medium containing a water-soluble active ingredient, and a voltage application that applies a predetermined voltage to the head part. Means and a light irradiation mechanism for selectively irradiating light of a specific wavelength from among a plurality of irradiable light having different wavelengths toward the distal direction of the head portion to be brought into contact with the skin surface. It is characterized by doing.

  Therefore, in this invention, the penetration effect of the active ingredient by ion-introducing a chemical solution or cosmetic liquid under the skin, the skin whitening effect by selectively irradiating light of a specific wavelength region, and the structure of the deep tissue of the skin Massage effect due to activation effect, chromotherapy effect when irradiated with light of visible wavelength, skin vitamin or provitamin penetration promotion effect by light and dynamic stimulation by vibration applied to skin surface Effective skin treatment can be performed in combination with effects.

  Moreover, in this embodiment, you may comprise a skin beautifying apparatus by adding to the said light irradiation mechanism the light source for irradiating several types of visible light and / or infrared rays from which hue mutually differs. That is, when a plurality of types of visible light are irradiated, a plurality of types of chromotherapy effects can be obtained efficiently. In addition, when irradiated with infrared rays, the absorption of moisture in the skin tissue is enhanced, and the activation of fibroblasts is enhanced by the arrival of light to the deep tissue of the skin. Collagen which gives gloss is effectively generated, and the skin-beautifying effect can be further improved.

  Furthermore, in this embodiment, the skin lightening device can be configured such that the light irradiation mechanism changes the hue of visible light to be irradiated and / or the presence or absence of infrared irradiation at predetermined time intervals. In this case, with a simpler operation, a plurality of types of effects obtained from individual lights having different wavelengths can be continuously given to the skin surface, and skin beautification can be performed efficiently.

  Further, in this embodiment, a head heating mechanism for heating the head unit may be added. In this case, pores are opened by the thermal effect, and activation of blood and lymph flow in the skin tissue can be achieved.

  As shown in FIG. 9, the skin beautifying apparatus according to this embodiment has an iontophoresis circuit 73 for supplying chemical liquid, cosmetic liquid, and the like as active ingredients to the skin beautifying apparatus 50 of the second embodiment. It has been added. Here, the head part 53 to be brought into contact with the skin surface of the skin beautification target is used as an ion introduction electrode, and the ion introduction circuit 73 functions as a voltage application unit that applies a voltage to the head part 53 as the electrode.

  Further, the controller 69 provided in the skin beautifying apparatus of this embodiment controls the iontophoresis circuit 73 so that the voltage is set so that the head portion 53 becomes the negative electrode (negative electrode) and the gripping electrodes 61 and 62 become the positive electrode (positive electrode). It is possible to execute at least a minus mode for applying and a plus mode for applying a voltage so that the head portion 53 becomes a positive electrode (positive electrode) and the gripping electrodes 61 and 62 become a negative electrode (negative electrode). Here, in the minus mode, the form of voltage application will be described with reference to the head unit 53. Continuous minus DC voltage (negative constant voltage) application, minus pulse voltage (DC pulse voltage alternating on the negative side) Application of a negative AC voltage or the like. In addition, a voltage supply in which a continuous negative DC voltage and a negative pulse voltage are superimposed may be performed. The minus pulse voltage is a rectangular wave that alternates between, for example, 0 V and −36 V within a frequency range of 1 to 2000 Hz, preferably 100 to 1000 Hz. On the other hand, in the plus mode, when the form of voltage application is described with reference to the head unit 53, application of plus pulse voltage (DC pulse voltage alternating on the positive side) or application of plus AC voltage is exemplified. In addition, voltage supply in which a continuous positive DC voltage (positive constant voltage) and a positive pulse voltage are superimposed may be performed.

  In the skin treatment by the minus / plus mode, a skin lotion or a cosmetic liquid, that is, cotton impregnated with a water-soluble active ingredient is prepared, and the skin beautifying treatment is performed by interposing between the head portion 53 and the skin surface. Alternatively, a lotion or a cosmetic liquid may be applied to the face, and the head portion 53 may be pressed against the face to allow the water-soluble active ingredient to penetrate into the skin surface of the face. Here, examples of the active ingredient include provitamin C.

  As the cosmetic treatment agent soaked into the cotton, various vitamins and ceramides, cosmetic ingredients such as collagen (including collagen beads) and whitening agents, cosmetic ingredients used as various cosmetics, UV absorbers, Examples include those containing skin protection components such as sunscreen inhibitors, moisturizers, oil replenishers, and inflammation inhibitors, and in some cases those containing facial cleansing components.

  Here, when the skin condition is, for example, dry skin and it is desired to remove stains and wrinkles, the negative mode is executed, and negative ions are introduced into the subcutaneous tissue, thereby activating skin cells. The pores open and moisturizes the skin. On the other hand, if the skin quality is greasy and you want to remove acne, etc., the plus mode can be used to calm the skin's cellular tissue, close pores, remove acne, and improve skin texture. It is done. In the skin beautifying device 50, for example, a cleansing function for removing dirt components such as mud and dust from the skin can be realized by impregnating cotton with water and further applying an iontophoretic electrode with a positive polarity.

  In addition to the minus mode and the plus mode, a treatment mode is prepared for the skin beautifying apparatus of the present embodiment. That is, in this mode, the head unit 53 to which a voltage for ion introduction is applied is further subjected to vibration of a low frequency of about 90 Hz through the eccentric motor 65 and is directed toward the skin surface side in which the head unit 53 is in contact. Irradiates visible light or infrared light having a specific wavelength (hue). In this case, aquaporins on the skin surface are opened by low-frequency vibration, and active ingredients such as chemicals and cosmetics are easily introduced into the skin. As a result, the tension of the skin is removed, the blood flow and the lymph flow are improved, and the metabolism of the skin can be increased.

  Therefore, according to the skin beautifying device of this embodiment, the penetration effect of the active ingredient on the beautifying skin by ion-introducing chemical liquid or cosmetic liquid under the skin, the skin whitening effect by selectively irradiating light in the wavelength region In addition, an effective skin beautification treatment can be performed by combining the tissue activation effect in the deep part of the skin and the chromotherapy effect when irradiated with light having a wavelength in the visible region.

  Moreover, you may make it perform the skin beautification treatment which introduce | transduces provitamin C (Asc2P: ascorbic acid-2-O-phosphate) as a free radical scavenger into the inside of skin using the skin beautifying apparatus of this embodiment. Here, since water-soluble provitamin C can be ionized unlike fat-soluble vitamin E or the like, skin treatment by an iontophoresis method can be applied. Thereby, it is possible to synergistically obtain the skin beautifying effect by ion introduction, the skin beautifying effect by light irradiation of the light emitting diode lamp (including the effect of generating cracks between cells), and the vibration effect by the eccentric motor 65 and the ultrasonic vibrator 63. it can. At this time, it is possible to obtain a skin-beautifying effect that tightens pores while removing cellulite inside the skin.

  Here, provitamin C to be introduced into the skin will be described in detail. Vitamin C prevents the loss of vitamin C transporter (AscTr [Ascorbic Acid Transformer]). That is, vitamin C protects the body from oxidation and free radicals (active oxygen). It is also faster than other antioxidants. This action is also called a front defender. Here, in beautiful skin, it is more important to keep vitamin C so as not to be interrupted than to maintain a lot of vitamin C in the body. That is, if a large amount of vitamin C is ingested at once, it rapidly decreases due to rebound. Therefore, as an ingestion method, it is important to ingest a small amount many times (eg, divided into about 6 times a day). Vitamin C has the property of being easily oxidized and decomposed due to the influence of OH groups. For this reason, it is taken into the body in the form of provitamin C (Asc2P: ascorbic acid-2-O-phosphate), which is made difficult to be decomposed and oxidized by binding phosphoric acid to OH groups. Unlike vitamin Asc2G (ascorbic acid-2-O-glucoside), which has a low conversion rate, provitamin C has a good conversion rate and is converted in blood in 2 to 6 hours. For this reason, it is suitable for introduction into the skin by the iontophoresis method.

  In other words, when provitamin C is ion-introduced into the skin (basement membrane, dermis) using the skin beautifying apparatus of the present embodiment, the basement membrane serving as a scaffold for creating skin cells between the epidermis and dermis can be effectively regenerated. it can. Thereby, even if the skin epidermis is damaged by acne, burns, etc., cells can proliferate using the basement membrane as a scaffold, and the skin can be regenerated. Here, simply applying to the skin surface does not introduce provitamin C to the basement membrane and the dermis, so that the amount of vitamin C is reduced and cell proliferation is also reduced, so that ion introduction is necessary.

  In other words, by using the skin beautifying device of this embodiment in combination with the vibration action and the light irradiation action by a light-emitting diode lamp, etc., and further introducing provitamin C into the skin (basement membrane, dermis), In addition, the increase in MMP-2 (collagen degrading enzyme) is suppressed in the skin, and collagen, elastin and the like effective for skin beautification are generated in the skin tissue, and treatment with a high skin beautifying effect can be performed. Here, the elastin produced in the skin tissue exhibits the effect of supporting the protein fiber / basement membrane (oxytran fiber) that secures the elasticity of the skin.

  The present invention has been specifically described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, an example in which the present invention is applied to a handy type (portable) skin-beautifying device has been described. Instead, a main control device including a controller 69 and a power supply device are incorporated. A stationary housing portion and the like, and a probe device that is connected to the housing portion and includes a head portion 53, light emitting diode lamps 501, 502, 503, 504, 505, 506, 507, etc., which are held by a user. The skin beautifying device of the present invention may be configured as a device of the type to be used. In the above-described embodiment, each light-emitting diode lamp is a one-chip mounting type that emits monochromatic light. However, a single light-emitting diode lamp is mounted on a plurality of chips that emit light of a plurality of wavelengths. A type of light emitting diode lamp can also be employed.

  In addition to the light-emitting diode lamp having the configuration, an intense pulsed light (IPL) may be mounted on the skin beautifying apparatus of the first to third embodiments. The intensity pulse light preferably has a structure that emits light having a center wavelength of about 560 nm in consideration of the effect of introduction into the dermis of the skin. For example, when the intense pulse light is mounted on the skin beautifying apparatus of the third embodiment, the skin beautifying effect by light irradiation of the intense pulse light and the skin beautifying effect by ion introduction can be synergistically obtained. In this case, a high introduction effect of, for example, provitamin C, which is an active ingredient of beautifying skin, can be obtained by performing treatment in the order of ion introduction treatment and light irradiation with intense pulse light.

  Here, the action of the treatment with the intense pulse light is illustrated. For example, when light emitted from an intense pulse light is irradiated onto the skin surface to which an active ingredient such as provitamin C is applied, a dye in the body (chromophore) reacts to become an excited state, resulting in an increase in temperature at the site. . Thereby, a gap (crack) is generated between cells, and an active ingredient such as provitamin C is easily introduced from this gap to the dermis.

  The present invention can also be applied as a slimming device, for example, by irradiating a meridian (acupuncture point) having a slimming effect on the body with light of a specific wavelength or applying a stimulus by vibration. It is.
