Meanwhile, in the description of the present invention, when it is determined that the gist of the present invention can be confused by a specific description of a related known structure or function, a detailed description thereof will be omitted.

Referring to fig. 1 to 5, a dermocosmetic apparatus 10 according to an embodiment of the present invention may include: a main body 100 for a user to hold; a measurement unit 200 capable of measuring the skin condition of a user; a display unit 300 capable of displaying the skin condition of the user measured by the measurement unit 200; and an operation unit 400 capable of applying one or more of light and a minute current to the skin of the user. However, what the beauty treatment apparatus 10 according to an embodiment of the present invention can apply is not limited to light and micro current, and the beauty treatment apparatus 10 may include applying vibration or ultrasonic waves.

The main body 100 forms an external appearance of the skin beauty appliance 10, and the constituent elements included in the skin beauty appliance 10 may be accommodated inside the main body 100 or provided on the main body 100.

The main body 100 may include: an upper surface 110 provided with a measurement unit 200 capable of measuring the skin condition of the user; a peripheral surface 120 for holding by a user when in use; and a bottom surface 130 located on the opposite side of the upper surface 110. Among them, the upper surface 110 may be formed in an oval shape, the bottom surface 130 may be formed flat at a lower portion thereof to be able to stand on the ground, and the peripheral surface 120 may be formed of four surfaces connecting the upper surface 110 and the bottom surface 130.

The upper surface 110 may be provided with a measurement section 200 capable of measuring the skin condition of the user and an operation section 400 capable of applying one or more of light and a micro current to the skin of the user.

The outer peripheral surface 120 may be provided with a display unit 300 capable of displaying the skin condition of the user and a button unit 500 for operating the operation unit 400.

Specifically, the display part 300 may be disposed to face the front surface at one side of the peripheral surface 120, and the button part 500 may be disposed to face a direction perpendicular to the front surface at the other side of the peripheral surface 120. Wherein the front face is understood to be the y-axis with reference to fig. 2. As described above, by disposing the display unit 300 and the button unit 500 to face in the vertical direction, the user can easily check the display unit 300 while pressing the button unit 500. The upper surface 110 may be formed as an inclined surface inclined at a predetermined angle with respect to a horizontal plane (XY plane). For example, as shown in fig. 3, the upper surface 110 may be an inclined surface having a height higher on one side than the other side with respect to the bottom surface 130 of the main body 100, and the measuring unit 200 and the operating unit 400 may be located on the same plane as the upper surface 110. As described above, by including the upper face 110 inclined at a predetermined angle, the user can contact the skin beauty apparatus 10 with the user's face in a comfortable posture.

In addition, a battery (not shown) may be provided inside the main body 100 to apply the power 620 to the skin beauty apparatus 10.

The measurement unit 200 can be understood as a structure capable of measuring the skin condition of the user. For example, the measurement unit 200 may include an oil-water content sensor that measures the oil-water content of the skin. The measuring unit 200 may further include an elastic force sensor for measuring the degree of elastic force together with the oil-water sensor.

The oil-water sensor may include a first electrode 210 that oscillates a preset frequency and a second electrode 220 that receives the oscillated frequency from the first electrode 210. At this time, the first electrode 210 and the second electrode 220 may be disposed in parallel on the same plane, and an insulator through which current does not flow may be disposed between the first electrode 210 and the second electrode 220.

The skin oil-water content can be calculated from the difference between the frequency value of the oscillation at the first electrode 210 and the frequency value received at the second electrode 220. Specifically, the frequency of oscillation at the first electrode 210 may be transmitted to the second electrode 220 through the skin of the user in contact with the first electrode 210.

In this case, the dielectric constant of the skin differs depending on the oil-water content of the skin of the user, and the frequency attenuation amount differs depending on the dielectric constant of the skin of the user when the frequency passes through the skin of the user. That is, when the frequency of oscillation of the first electrode 210 is measured at the second electrode 220 through the skin, the oil-water component of the skin of the user can be measured by the frequency measured at the second electrode 220.

The oil-water component of the skin can be calculated from the frequency change amount measured by the measurement unit 200, and for this purpose, the data on the oil-water component at a specific frequency and the frequency change amount can be stored in the memory 610.

In addition, the frequency of oscillation at the first electrode 210 can be changed by the control section 600. That is, the control unit 600 may change the frequency of oscillation at the first electrode 210 according to the manufacturer's setting or the user's setting, and for this reason, the beauty treatment apparatus 10 may further include an operation unit (not shown) for allowing the user to select the frequency. Wherein the frequency may be 3 kHz.

In the above embodiment, the case where the frequency is oscillated at the first electrode 210 and the frequency of the oscillation is received at the second electrode 220 has been described, but the case where the frequency is oscillated at the second electrode 220 and the frequency of the oscillation is received at the first electrode 210 may be included.

The description has been given of the case where the first electrode 210 and the second electrode 220 of the measurement unit 200 oscillate and receive frequencies, but the measurement unit 200 is not limited to this. For example, the first electrode 210 and the second electrode 220 of the measurement unit 200 may measure the skin voltage and convert the measured skin voltage into the oil-water content of the skin. In this case, data related to the oil-water component of the skin-based voltage measurement value may be stored in the memory 610.

In the above embodiment, the measurement unit 200 is exemplified as an oil-water sensor that measures an oil-water amount, but the measurement unit 200 is not limited to this.

For example, the measurement unit 200 may further include an elastic force sensor (not shown) for measuring the elastic force of the skin. Specifically, the elastic force sensor may further include: a pressure sensor including a strain gauge (strain gage), or a probe having one end in contact with the skin to be pressurized, an elastic member connected to the other end of the probe to be in contact with the FSR sensor, and the FSR sensor connected to the elastic member to measure the pressure and thereby the elastic force of the skin.

The measurement unit 200 may be located on the same plane as the operation unit 400. By having the above arrangement relationship, the skin condition can be measured by the measurement unit 200 while applying light irradiation and a micro current to the skin by the operation unit 400.

The first and

second electrodes

210 and 220 may be positioned on the upper surface 110 of the body 100 in parallel with each other. In addition, the first electrode 210 and the second electrode 220 may be arranged in parallel with the electrode part 420 along the edge of the upper face 110 without contacting each other.

The first and

second electrodes

210 and 220 may be located on the upper 20% of the height in the z direction at the inclined upper face 110. In this case, the user can easily bring the first electrode 210 and the second electrode 220 located at the high portion of the upper surface 110 into contact with the skin.

The skin condition of the user measured by the measurement unit 200 can be displayed on the display unit 300, and a plurality of recommendation modes described later can be displayed on the display unit 300.

The display part 300 may include a plurality of LEDs capable of displaying a plurality of colors. Specifically, one LED may display a plurality of colors. As described above, by providing a plurality of LEDs displaying a plurality of colors, information about the skin state and the recommended mode can be transmitted to the user through the display section 300. However, the means is not limited to the LED as long as it can display the skin state and a plurality of recommended modes described later, and the display unit 300 may include a display unit using a display.

In the present embodiment, a case where the display unit 300 is a plurality of LEDs capable of displaying a plurality of colors will be described.

The display part 300 may be disposed at the peripheral surface 120 of the main body 100. However, the position of the display part 300 on the main body 100 is not limited as long as the user can see the display part with the naked eye.

The display unit 300 can display the skin condition of the user measured by the first electrode 210 and the second electrode 220, based on the number of lit LEDs, the color, and the blinking. Here, the number of leds of the LE D as the display unit 300 can be understood as a number that can be recognized by the naked eye of the user.

For example, it can be understood that the first color of the display 300 represents the moisture content of the skin, the second color represents the oil content of the skin, and the third color represents the elasticity of the skin. Wherein the first color may be Blue (Blue), the second color may be Yellow (Yellow), and the third color may be Red (Red).

The first color displayed when the moisture of the skin is insufficient may correspond to a color (blue) of a wavelength band effective for improvement of the moisture content of the skin, the second color displayed when the oil content of the skin is insufficient may correspond to a color (yellow) of a wavelength band effective for improvement of the oil content of the skin, and the third color displayed when the elasticity of the skin is insufficient may correspond to a color (red) of a wavelength band effective for improvement of the elasticity of the skin. Thus, the user can intuitively grasp which skin improvement function the skin condition is in a relatively insufficient portion (moisture, oil, elasticity) of the skin condition of the user and a recommended mode to be managed.

The number of lights on the display unit 300 can quantitatively display the moisture amount, the oil amount, and the spring force. Further, the flicker (repeated lighting and extinction) of the display unit 300 can indicate the shortage of the moisture amount, the oil amount, the elasticity, and the like.

When the skin condition of the user is measured by the skin care apparatus 10 and the moisture content is insufficient, one display section 301 may blink to display blue. In this case, the number of lights on the display unit 300 may indicate the shortage of the moisture amount. For example, it can be understood that the display unit 300 shows excellent quality when the number of lights is 4, good quality when the number of lights is 3, dry when the number of lights is 2, and poor dryness when the number of lights is 1.

In addition, when the skin state is insufficient in oil content, one display portion 301 may display yellow and blink.

In addition, when the skin state is insufficient in elasticity, the display unit 300 may blink to display red. When the state of the skin is insufficient for the oil and water to be both in the same variation, one display unit 301 may blink to display red.

Wherein, when the moisture measurement value is less than a preset average moisture value of a person, a blue flash indicating a moisture deficiency may be displayed. When the oil content measurement value is less than a preset average human oil content value, a yellow flicker indicating insufficient oil content may be displayed. When the elasticity of the skin is insufficient, or the moisture measurement value and the oil measurement value are larger than the preset average moisture value and average oil value of the person, or the deviation between the two measurement values is the same or 0, red flicker may be displayed. At this time, the degree of water shortage, the degree of oil shortage, and the degree of elasticity shortage may be judged from the difference between the preset average values.

In addition, when the moisture measurement value is smaller than the preset average moisture value of the person and the oil measurement value is also smaller than the preset average oil value of the person, the color displayed (recommended mode color) may be controlled according to the degree of a large difference from the average value. For example, when the moisture measurement value is 30, the preset average moisture value of the person is 40, and the oil measurement value is 18, and the preset average oil value of the person is 20, it is determined that the moisture content is less than the oil content, and a blue flicker indicating that the moisture content is less is displayed on the display unit 300.

In addition, when the display unit 300 can display a plurality of colors, the color with the largest deviation can be displayed by comparing with a preset average value, and when all the deviations are the same, the display priority order can be set to red, blue, and yellow. However, the concept of the present invention is not limited to the order, and can be set to order combinations other than the order.

In addition, the concept of the present invention is not limited thereto, and the display part 300 may include a case where one display part 301 displays only one color. In this case, the skin condition such as the moisture content, the oil content, and the elasticity can be displayed by a plurality of (row) display units. For example, the display unit 300 may be configured to have 3 rows, the first row may display the moisture content of the skin, the second row may display the oil content, and the third row may display the degree of elasticity.

The display unit 300 may display a skin state according to the oil-water content of the skin measured at the first electrode 210 and the second electrode 220, and may display a plurality of recommended modes that recommend a wavelength band of light and a magnitude of a micro current applied at the operation unit 400 based on the oil-water content.

Wherein the plurality of recommendation modes may include: a first recommended mode in which a first wavelength band of light and a first magnitude of a micro-current to be applied to the operation portion 400 are recommended; a second recommended mode that recommends a second wavelength band of light and a second magnitude of micro-current to be applied at the operation portion 400; and a third recommended mode in which a third wavelength band of light and a third magnitude of micro-current are recommended to be applied to the operation portion 400.

Specifically, the first recommended mode may be used as a recommended function for supplementing moisture when the moisture content of the skin is insufficient, the second recommended mode may be used as a recommended function for supplementing oil when the oil content of the skin is insufficient, and the third recommended mode may be used as a recommended function for improving the elasticity when the elasticity of the skin is insufficient, or the moisture content and the oil content of the skin are sufficient, or the deviation between the moisture content and the oil content is the same or 0.

The operating part 400 may apply one or more of light and micro current to the skin of the user. In the embodiment of the present invention, a case where the operation unit 400 includes the light source 410 that can emit light and the electrode unit 420 that can apply a minute current will be described. However, the concept of the present invention is not limited thereto, and the operation portion 400 may further include a vibration portion (not shown) for applying vibration and an ultrasonic portion (not shown) for applying ultrasonic waves.

The operating part 400 may include: a light source 410 that can irradiate light of different wavelength bands; and an electrode part 420 generating a potential difference at the skin of the user, thereby being capable of changing the electrical environment of the skin. In addition, the operating part 400 may include a light-transmissive cover 430 disposed in front of the light source 410.

The light source 410 may generate light having a predetermined wavelength band so as to irradiate toward the skin side of the user. The light having the predetermined wavelength band irradiated by the light source 410 permeates the skin, thereby enabling the skin improvement effect (increase of moisture amount, improvement of uniformity and transparency of the skin, improvement of elasticity, etc.) based on the wavelength of the light.

The light source 410 is disposed inside the main body 100 and may be covered by a light-transmissive cover 430, and light irradiated by the light source 410 may be transmitted to the skin through the light-transmissive cover 430. Wherein the light source 410 may include a plurality of light emitting elements that illuminate light of different wavelength bands.

For example, the light source 410 may be a single chip type in which a plurality of light emitting elements in the form of LEDs for emitting light of different wavelength bands are mounted on one substrate.

The light source 410 may illuminate different wavelength bands of light. For example, the light source may irradiate a first wavelength band, a second wavelength band and a third wavelength band of light, wherein the first wavelength band may be 480nm, the second wavelength band may be 610nm, and the third wavelength band may be 650nm, respectively. At this time, the light delivered to the skin based on the first wavelength band may display blue, the light delivered to the skin based on the second wavelength band may display yellow, and the light delivered to the skin based on the third wavelength band may display red. The first wavelength band may be understood as a first color illumination interval, the second wavelength band may be understood as a second color illumination interval, and the third wavelength band may be understood as a third color illumination interval.

As described above, by irradiating the skin with one or more of the first to third wavelength bands, effects of calming the skin, improving the skin texture, calming care of sensitive skin, improving the skin profile, improving the skin elasticity, restoring the skin elasticity, improving the skin lift, improving the skin luster, and the like can be obtained by one apparatus. It is understood that the first wavelength band is most effective in improving moisture, the second wavelength band is most effective in improving oil, and the third wavelength band is most effective in improving elasticity. However, each band may not only show one of the above-described effects but also show the skin improvement effect in combination.

The wavelength band that the light source 410 of the present invention can irradiate is not limited to the above-described embodiment, and other wavelength bands suitable for the skin improvement effect may be selected.

The light source 410 may be continuously turned on, and may be repeatedly turned on and off. On the other hand, the selection of the wavelength band of the light source 410 can be realized by the button part 500 described later.

The electrode part 420 may generate a potential difference at the skin of the user, thereby providing a micro current capable of changing the electrical environment of the skin. The electrode part may include a pair of

contact electrodes

420a, 420b disposed at the same plane and separated from each other to form a closed circuit with the skin when being in contact with the skin of the user, thereby generating a potential difference at the skin of the user. The pair of

contact electrodes

420a, 420b, when the power source 620 is applied, generate a potential difference at the skin of the user, changing the electrical environment of the skin, thereby enabling increased skin permeation of the ionic drug. Specifically, the pair of

contact electrodes

420a and 420b are used to exhibit an iontophoresis function, and a direct current is applied to the body of the user by a power supply 620 supplied from a battery (not shown), so that the skin of the user and the pair of

contact electrodes

420a and 420b form a closed circuit, thereby generating the movement of ions. Thus, when the cosmetic applied to the skin is ionized, the cosmetic easily permeates into the tissues in the skin through the skin mucosa, and the effect of iontophoresis can be produced.

As described above, the pair of

contact electrodes

420a, 420b may be spaced apart on the same surface of the upper surface 110. The pair of

contact electrodes

420a and 420b may be implemented by a bipolar (bi-polar) system that is fixed to the upper surface 110 in a spaced-apart manner.

When the upper surface 110 is brought into contact with the skin in a state where the cosmetic is applied to the body part to be treated by the user, the pair of

contact electrodes

420a and 420b provided on the same surface at a distance from each other can be simultaneously brought into contact with the skin. Thus, even if the user changes the holding position of the main body 100 during use, the pair of

contact electrodes

420a and 420b are always kept in contact with the skin, and the iontophoresis function can be exhibited.

The pair of

contact electrodes

420a, 420b may be constituted by a plate-shaped member having a predetermined area to be able to widen the contact area with the skin. As an example, the pair of

contact electrodes

420a, 420b may be formed along corners of the upper face 110 and provided in a shape in which the light source 410 can pass through the center of the pair of

contact electrodes

420a, 420 b. Specifically, the pair of

contact electrodes

420a and 420b may be disposed on the same plane as the measurement section 200, and one side is formed shorter than the other side so that the measurement section 200 can be disposed between the pair of

contact electrodes

420a and 420 b.

In addition, the overall shape of the pair of

contact electrodes

420a and 420b and the measurement section 200 may be in an elliptical ring shape to allow light irradiated by the light source 410 to be transmitted to the outside.

In addition, corners formed by edges of the pair of

contact electrodes

420a, 420b may be formed as curved surfaces. Thus, the pair of

contact electrodes

420a and 420b can prevent the skin of the user from being damaged by sharp corners in the process of rubbing the skin of the user by contacting the skin of the user.

In addition, the pair of

contact electrodes

420a, 420b may protrude by a predetermined distance degree with respect to the upper face 110. Thus, when the skin beauty apparatus 10 is in contact with the skin, light emitted from the light source 410 can be prevented from leaking to the outside by the pair of

contact electrodes

420a, 420 b.

In one aspect, the micro-current generated by the pair of

contact electrodes

420a, 420b may have various magnitudes. In the present embodiment, a case where the magnitude of the micro-current generated through the pair of

contact electrodes

420a, 420b shows the magnitude of three kinds of intensities (first magnitude, second magnitude, third magnitude) is exemplified.

The first size generated by the pair of

contact electrodes

420a, 420b may be set to be simultaneously generated when the light of the first wavelength band generated by the light source 410 is irradiated. The second size may be set to be simultaneously generated when the light of the second wavelength band generated by the light source 410 is irradiated. The third size may be set to be simultaneously generated when the light of the third wavelength band generated by the light source 410 is irradiated. Here, the micro-current is understood to be a magnitude that becomes stronger in the order of a first magnitude, a second magnitude, and a third magnitude.

As described above, when the light of the first wavelength band and the weak micro-current are transmitted to the skin and the skin beauty apparatus 10 is rubbed on the skin to which the cosmetic is applied, the increase of the moisture content of the skin can be promoted.

When the skin care device 10 is rubbed on the skin to which the cosmetic is applied by transmitting the light of the second wavelength band and the micro-current of the intermediate intensity to the skin, the oil content of the skin can be increased to make the skin glossy.

In addition, when the skin beauty apparatus 10 is rubbed against the skin to which the cosmetics are applied by transmitting light of the third wavelength band and a micro-current of a strong magnitude to the skin, the elasticity of the skin can be improved.

In addition, the operating part 400 may operate in a plurality of operating modes to control the wavelength of light emitted by the light source 410 and the micro current flowing out by the electrode part 420. For example, the operation mode of the operation part 400 may have a first operation mode in which a first wavelength band of light and a first magnitude of a micro current are applied; a second mode of operation in which a second band of light and a second magnitude of microcurrent are applied; a third mode of operation in which a third band of light and a third magnitude of microcurrent are applied; at least two of the first operation mode, the second operation mode, and the third operation mode operate in a fourth operation mode for a preset time.

As described later, the operation mode may be selected by the button unit 500, or may be operated when the contact sensor 230 is brought into contact with the skin when the color displayed on the display unit 300 appears.

The button part 500 may include: a work button 510 capable of selecting one of the first to fourth operation modes; and a notification unit 520 for displaying a plurality of colors so that whether the first to fourth operation modes are selected or not can be confirmed.

The first operation mode can be sequentially switched to the fourth operation mode by clicking the work button 510, and the display can be displayed by the notification section 520.

For example, the notification unit 520 may display blue representing the first operation mode, yellow representing the second operation mode, red representing the third operation mode, and white representing the fourth operation mode, and may select one of the first to fourth operation modes by operating the operation button 510.

In addition, four operation modes (first to fourth operation modes) are explained in the above-described embodiment, however, the concept of the present invention is not limited thereto, and the skin beauty apparatus 10 may further include fifth to eighth operation modes. For example, the operation modes of the operating part 400 may further include a fifth operation mode in which a minute current is not applied but only light is applied, a sixth operation mode in which a minute current is not applied but only light is applied, a seventh operation mode in which a minute current is not applied but only light is applied, and an eighth operation mode in which a minute current is not applied but only light is applied. In this case, one of the first to eighth operation modes may be selected through the button part 500, or may be activated when the contact sensor 230 is brought into contact with the skin when the color displayed by the display part 300 appears.

The color of the notification portion 520 may be controlled by the control portion 600 to be the same color as the color displayed on the display portion 300.

By pressing the operation button 510, the color displayed on the display section 300 and the notification section 520 can be changed, and thereby the wavelength band of light applied to the skin and the minute current can also be changed.

In addition, the operation button 510 may be used to turn on/off (on/off) the power of the skin beauty apparatus 10. For example, when the power of the beauty treatment apparatus 10 is turned off, the beauty treatment apparatus 10 may be turned on by pressing the operation button 510 for three seconds or more, and when the power of the beauty treatment apparatus 10 is turned on, the beauty treatment apparatus 10 may be turned off by pressing the operation button 510 for three seconds or more.

In addition, the skin beauty apparatus 10 may further include a contact sensor 230 for sensing whether contact with the skin is made, and the contact sensor 230 may include a pressure sensor or an electrostatic capacity sensor.

When the contact sensor 230 is used in the dermocosmetic apparatus 10, the light source 410 may illuminate only if the skin is sensed by the contact sensor. At this time, the contact sensor 230 may be disposed at a portion of the upper face 110. For example, the contact sensor 230 may be disposed in the vicinity of the measurement section 200 on the light-transmissive cover 430. More specifically, the contact sensor 230 may be disposed between the measuring part 200 and the light source 410 inside the light-transmissive cover 430.

By the contact sensor 230, the light irradiated by the light source 410 can be irradiated only in a state where the pair of

contact electrodes

420a, 420b is in contact with the skin. In this case, it is possible to prevent the user's eyesight from being injured by the light emitted from the light source 410.

In addition, the dermocosmetic apparatus 10 can include a distance sensor (not shown) for sensing the distance between the light source and the skin.

The distance sensor (not shown) may be provided on the circuit substrate on which the light source is mounted. Wherein the circuit substrate may be disposed at a rear side of the light transmissive cover 430.

When the beauty treatment apparatus 10 uses a distance sensor (not shown), the light source 410 may irradiate only in a case where the distance sensed by the distance sensor is within a preset range.

In addition, the skin care apparatus 10 may store information on the moisture content and the oil content of the skin sensed by the measurement unit 200 in the memory 610.

In addition, the skin beauty apparatus 10 may include a control part 600 that controls the display part 300 to display a plurality of recommended modes that recommend a wavelength band of light emitted from the light source 410 and a magnitude of micro-current applied at the electrode part 420 based on the moisture content and the oil content sensed at the measurement part 200.

In addition, after the skin state is measured by the measurement unit 200 and the result is displayed on the display unit 300, the control unit 600 may control the operation unit 400 to activate the corresponding recommendation mode when the contact sensor 230 is in contact with the skin (sensing contact) without additional operation by the user.

In addition, the control part 600 controls the light source 410 and the electrode part 420 to correspond to the recommended mode displayed in the display part 300, thereby being capable of applying light having a specific wavelength band to the skin and delivering a micro current having a specific magnitude to the skin.

In addition, when the beauty treatment apparatus 10 includes the contact sensor 230 or the distance sensor (not shown), the control part 600 may control the contact sensor 230 and the distance sensor.

The control unit 600 may display a color corresponding to any one of the plurality of recommended modes on the display unit 300 according to the range of the result value measured by the measurement unit 200, and may set the operation unit 400 to emit light having the same color band even if the range of the result value measured by the measurement unit 300 is different.

Specifically, as shown in table 1 below, the light source 410 of the operation unit 400 may have an operation sequence in which the unit irradiation wavelength interval is repeated twice based on the measurement result value (measurement voltage) measured by the measurement unit 200.

Wherein, the wavelength band of the light irradiated by the light source 410 may have a unit irradiation wavelength interval, and the unit irradiation wavelength interval may include a first color irradiation interval irradiating blue; irradiating a yellow second color irradiation section; and a third color illumination zone for illuminating red.

[ TABLE 1 ]

	Measuring voltage (V)	Color of light source
			Level 1	0.10-0.29	Blue color
Level 2	0.30-0.37	Yellow colour
			Level 3	0.38-0.40	Red colour
Level 4	0.41-0.50	Blue color
			Level 5	0.51-0.65	Yellow colour
Level 6	Above 0.66	Red colour

The control unit 600 may control the light source to repeat irradiation of light in a wavelength range at least once for each unit including the first color irradiation section (blue), the second color irradiation section (yellow), and the third color irradiation section (red). Preferably, the control part 600 may control the light source to repeat the irradiation of the light of the unit irradiation wavelength zone including the first color irradiation zone, the second color irradiation zone, and the third color irradiation zone at least twice.

Wherein, the wavelength band of the light irradiated in the first color irradiation region can be 400-480nm, the wavelength band of the light irradiated in the second color irradiation region can be 550-610nm, and the wavelength band of the light irradiated in the third color irradiation region can be 610-650 nm.

Although the skin condition is classified by the voltage V measured by the measurement unit 200 in table 1, the skin condition may be classified according to the frequency of measurement as described above.

The control part 600 controls the light source 410 as described above, so that the user can obtain light of various wavelength bands by irradiation of the skin beauty appliance 10 even in consideration of each season or physical characteristics of the individual.

Specifically, the measurement voltage V is measured to be low (for example, in the range of level 1 to level 3 in table 1) for a user whose oil-water content is relatively low according to the season or physical characteristics, and the measurement voltage V is measured to be high (for example, in the range of level 4 to level 6 in table 1) for a user whose oil-water content is relatively high. However, in this case, the control unit 600 may control the operation unit 400 so that the unit irradiation wavelength interval is repeated, and the user may irradiate light having a plurality of wavelength bands.

The skin care apparatus 10 may further include a notification unit (not shown) for notifying the skin condition measured by the measurement unit 200. The notification unit may include any known means such as an LED or a sound displayed on the upper portion of the button unit 500.

Fig. 6 is a sequence diagram illustrating a control method of the beauty treatment apparatus of fig. 1.

A control method of the skin beauty apparatus 10 according to an embodiment of the present invention is observed as follows with reference to fig. 6.

When the button part 500 is pressed, the power of the beauty treatment apparatus 10 can be turned on (S1).

Then, when the measurement unit 200 is in contact with the skin (when the user brings the skin care apparatus 10 into contact with the skin of the user), the skin condition can be measured (step S2). At this time, the display for ending the skin condition measurement may be displayed by at least one of a notification sound and light emitted from the button unit 500 and the display unit 300.

Then, the control unit 600 may determine a recommended mode suitable for the skin condition, and the recommended mode suitable for the skin among the recommended modes is displayed on the display unit 300 (S3). For example, when the skin condition measured by the measurement unit 200 is a moisture-deficient condition, the display unit 300 may display a blue color and blink to display the moisture-deficient condition. Here, the blue color displayed on the display part 300 may represent the first recommendation mode.

Then, the notification unit 520 of the button unit 500 may display the same color as the color displayed on the display unit 300, switch to the selection mode by operating the operation button 510, or perform the recommendation mode by bringing the contact sensor into contact with the skin without operating the operation button 510 (S4). For example, when the same color as the color displayed on the display unit 300 is displayed on the notification unit 520, the skin care apparatus 10 is brought into contact with the skin without operating the operation button 510, and the contact sensor 230 may sense whether or not the skin is in contact with the skin, thereby executing the recommended mode. In contrast, after the same color as that displayed on the display unit 300 is displayed in the notification unit 520, one of the first to fourth operation modes is selected by operating the work button 510, and the selection mode can be executed.

When the recommended mode is executed, the control part 600 may apply a band based on the recommended mode and a micro current to the skin (S5). For example, a first band of light and a first magnitude of micro-current may be applied to the skin as the first recommended mode based on insufficient moisture is executed.

On the other hand, when the operation notification unit 520 has a color different from the color displayed on the display unit 300 by operating the operation button 510 and the skin beauty apparatus 10 is brought into contact with the skin, the contact sensor 230 recognizes the contact with the skin and can execute the selection mode. When the selected mode is performed, a band based on the selected mode and a micro current may be applied to the skin (S6).

The selection mode may include applying light of a specific wavelength band and a micro-current to the skin through the operation portion 400, and may include an operation sequence in which a unit irradiation wavelength interval including the first color irradiation interval, the second color irradiation interval, and the third color irradiation interval is repeated once or more (preferably twice or more).

While the operation unit 400 is in contact with the skin and light and micro-current are applied to the skin, the measurement unit 200 may be in contact with the skin to measure the moisture content and the oil content of the skin, and the display unit 300 may display the degree of improvement in at least one of the moisture content and the oil content (S7). For example, the degree of improvement in the moisture content can be indicated by an increase in the number of blue lights, the degree of improvement in the oil content can be indicated by an increase in the number of yellow lights, and the degree of improvement in the spring force can be indicated by an increase in the number of red lights.

When the operation unit 400 ends the operation, the display unit 300 may display the skin improvement degree (S8). For example, when the operation unit 400 operates in the first operation mode, the number of lights of the display unit that can display blue color representing the degree of skin improvement with the replenishment of moisture. Specifically, the skin state before the skin care apparatus 10 is started up is one blue display portion that indicates a shortage of moisture is blinking, and the skin state after the skin care apparatus 10 is started up can be represented by four blue display portions that indicate a replenishment of moisture.

Then, the power of the beauty treatment apparatus 10 may be turned off automatically or by operating the operation button 510 (S9).

By repeating this process for a certain period of time by the skin care apparatus 10, skin improvement effects (increase in moisture amount, improvement in skin uniformity and transparency, improvement in elasticity, etc.) can be obtained.

The effects of the skin beauty apparatus and the method of using the same according to the embodiment of the present invention are explained as follows.

The skin beauty apparatus 10 according to an embodiment of the present invention has an advantage in that it can diagnose a skin condition and improve the skin condition.

In addition, the skin beauty apparatus 10 may apply light and micro current suitable for the skin condition, thereby providing a customized effect for improving the skin condition.

In addition, the skin beauty apparatus 10 has an advantage that light of different wavelength bands and a micro current can be simultaneously applied.

In addition, when the recommended mode is executed, the color displayed on the display unit 300, the color displayed on the button unit 500, and the color of the light source applied to the skin by the operation unit 400 may be the same. In this case, the user can visually and easily recognize the color of light and the magnitude of the micro current that the user wants to operate.

In addition, the light source 410 of the operating part 400 generates light having a predetermined wavelength band and irradiates toward the skin side of the user, so that the user can obtain a skin improvement effect (increase of moisture amount, improvement of uniformity and transparency of the skin, improvement of elasticity, etc.) according to the wavelength penetrating the skin.

When a dc current is applied to the pair of

contact electrodes

420a and 420b of the operation unit 400 to ionize the cosmetic applied to the skin of the user, the cosmetic easily penetrates into the tissue inside the skin through the skin mucosa, and an effect of ion introduction can be produced.

In addition, when light of the first wavelength band (400-. In addition, when light of the second wavelength band (550-610nm) and a micro-current of an intermediate intensity are transmitted to the skin and the skin beauty apparatus 10 is rubbed on the skin to which the cosmetics are applied, the oil content of the skin can be increased. In addition, when light of the third wavelength band (610-650nm) and a micro-current of a strong magnitude are transmitted to the skin and the skin beauty apparatus 10 is rubbed on the skin to which the cosmetics are applied, the elasticity of the skin can be improved.

The first electrode 210 and the second electrode 220 are located at the highest portion of the inclined upper face 110. With this arrangement, the user can bring the highest portion of the upper surface into contact with the skin, and the skin condition can be measured more easily.

By providing the distance sensor or the contact sensor, the light emitted from the light source 410 is generated in a state of being in contact with the skin or within a predetermined distance from the skin, and thus the user can be prevented from seeing the light emitted from the light source 410.

Fig. 7 is a plan view showing the measuring section and the operating section according to another embodiment of fig. 4 from above. Since the embodiment shown in fig. 7 is compared with the embodiment shown in fig. 4, the difference in shape between the measuring section and the operating section is mainly described in terms of difference, and the description and reference numerals of the first embodiment are applied to the same portions.

At this time, the first electrode 210 'and the second electrode 220' may be concentric circles.

The concentric circles between the first electrode 210 'and the second electrode 220' are insulators, which can electrically insulate the first electrode 210 'from the second electrode 220'.

In fig. 7, the first electrode 210 'is disposed on the inner side and the second electrode 220' is disposed on the outer side, but is not limited thereto, and the positions thereof may be changed.

In addition, the first and second electrodes 210 'and 220' may be located at the highest portion of the inclined upper face 110. With this arrangement, the user can bring the highest portion of the upper surface 110 into contact with the skin, and the skin condition can be measured more easily.
