Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Sensitive muscles are a type of symptoms that describe the susceptibility of skin, including, among others, the tendency to develop redness, edema, scalding, stinging, itching, desquamation, etc. when stimulated. Its principal mechanisms are associated with impaired skin barrier, and causes include various self-skin inflammatory diseases, irritant substance exposure, excessive cleansing, excessive use of functional skin care products, and the like. When the skin barrier is damaged, the skin is prone to inflammatory reactions, water-oil imbalance, and the above-mentioned sensitive symptoms are exhibited. Therefore, the method for improving the sensitive muscles mainly comprises barrier repair, and the barrier repair can enhance the tolerance of the skin and reduce the sensitivity, thereby playing a role in improving the sensitive muscles.

However, the sensitive muscles have different capacities for external stimuli during different recovery phases, so that different repair modes are required for different recovery phases.

Referring to fig. 1 and 2, an embodiment of the present application provides a skin care device, which includes a housing 20, a control module 40, and one or more care modules 10.

The control module 40 is disposed in the housing 20, and the control module 40 is used for controlling the nursing module 10 to work so as to realize a beauty function.

The care module 10 is disposed in the housing 20 or disposed on the surface of the housing 20, the care module 10 is electrically connected to the control module 40, and the care module 10 is configured to output cosmetic energy to the outside of the housing 20, where the cosmetic energy includes at least one of radio frequency, temperature, and light.

The skin care device has at least two different modes of operation in which the cosmetic energy released by the care module 10 is different. The cosmetic energy difference comprises two dimensions, one of which is that the kind of cosmetic energy is at least partially different, e.g. the operating mode comprises a first mode in which the skin care device releases radio frequency and a second mode in which the skin care device releases radio frequency and light. For another example, the skin care device releases radio frequency in a first mode and releases light in a second mode. As long as the kind of energy released by the care module 10 in the first mode and the second mode is not exactly the same, it should be understood that the kind of cosmetic energy released by the care module 10 in the first mode and the second mode is at least partially different.

The second is that when the types of beauty treatment energy are identical, the amounts of the same beauty treatment energy are different, for example, the care module 10 releases a lower rf intensity in the first mode and releases a higher rf intensity in the second mode. For another example, the light intensity released by the care module 10 in the first mode is the same as the light intensity released in the second mode, but the radio frequency intensity released by the care module 10 in the first mode is lower and the radio frequency intensity released in the second mode is higher. When the types of cosmetic energy are the same, the amounts of the same type of cosmetic energy are not exactly the same, it should be understood that the amounts of cosmetic energy released by the care module 10 in the first mode and the second mode are different.

That is, the skin care device may be considered to have the same cosmetic energy in the first mode as in the second mode only if the types of cosmetic energy released by the skin care device in the first mode and the second mode are identical and the amounts of the same cosmetic energy are also identical. In addition to this, the skin care device may be considered to have different cosmetic energies in the first and second modes.

Because the skin care device is different in the beauty energy released under different working modes, the skin in different states can be repaired better by changing the types of the beauty energy and the corresponding quantity of the types.

Referring to fig. 2, in some embodiments, the care module 10 includes a radio frequency unit 13 and a heat exchange unit 11.

The radio frequency unit 13 is disposed in the housing 20 or disposed on a surface of the housing 20, the radio frequency unit 13 is electrically connected to the control module 40, and the radio frequency unit 13 is configured to release radio frequency to the outside of the housing 20. By the effect of radio frequency, epithelial cell proliferation can be promoted, so that the tissue between epidermis and dermis is thickened, and the skin sensitivity problem is improved.

Studies have shown that the skin wound healing process, and healing rate, is faster, and the healed epidermis is more like normal skin, rather than scar tissue, which is typical of secondary wound healing. The radio frequency treatment can accelerate the healing process of the skin wound surface, so that the skin is smoother after healing. The radio frequency may create a rapidly varying pulsed electromagnetic field that may stimulate endothelial cell regeneration and reestablish injured blood vessels, increasing angiogenesis in the affected tissue of the injury over time. The pulsed electromagnetic field may also stimulate fibroblasts to rebuild damaged extracellular matrix, stimulate epithelial cell proliferation, and restore lost tissue continuity. The pulsed electromagnetic field also promotes the production of ATP (adenosine triphosphate), accelerates wound healing, and reduces inflammatory responses.

The heat exchange unit 11 is disposed in the housing 20 or disposed on a surface of the housing 20, the heat exchange unit 11 is electrically connected to the control module 40, and the heat exchange unit 11 is configured to release temperature outside the housing 20. The temperature includes heat or cold, and the heat exchange unit 11 may release the heat or cold to adjust the temperature of the skin, so that the skin care device may cool or heat the skin of the user and maintain a desired specific temperature during the cool or heat. For example, when the cold compress temperature is lower than 24 ℃, the skin can be subjected to pain relieving and red swelling relieving effects, and when the hot compress temperature is higher than 30 ℃, the blood circulation can be accelerated, and the cell regeneration can be promoted.

Research shows that the low temperature can resist inflammation, and the specific action mechanism is as follows:

the low temperature can reduce the TNF-alpha (tumor necrosis factor alpha) of the human body, and the TNF-alpha can change the sugar metabolism of target cells, so that the pH in the cells is reduced, and the cells die.

The low temperature can reduce IL-1 alpha (interleukin 1 alpha) of human body, and the IL-1 alpha can cause skin fever.

The low temperature can reduce PGE2 (prostaglandin E2) in human body, and PGE2 can cause skin pain and inflammation.

The low temperature can raise IL-6 (interleukin-6) in human body, and the IL-6 can stimulate proliferation of activated B cells, secrete antibody, stimulate proliferation of T cells and activation of CTL.

The low temperature can raise the up-regulated IL-10 (interleukin 10) of human body, and the IL-10 can regulate the growth and differentiation of cells, and is involved in inflammatory reaction and immune reaction, and is a recognized inflammation and immune inhibitor.

The low temperature treatment can resist oxidation and inflammatory pigmentation, and is helpful for preventing skin color darkness caused by long-term facial inflammation. It also has effects in constricting blood vessel, reducing vascular permeability, and preventing erythrocyte of erythema type skin. It also has effects of reducing edema, decreasing nerve sensitivity, resisting oxidation, reducing generation of ROS reactive oxygen species, reducing histamine release, reducing inflammatory color deposition, improving water loss and epidermis hydration, and maintaining stable epidermis pH value and other parameters, and is very important for sensitive muscle users and users after medical and artistic.

The temperature of the temperature output by the heat exchange unit 11 in the first mode and the second mode is different, so that the skin of different states can be adapted.

For example, the skin care device heats skin tissue by radio frequency to achieve skin tightening care. However, for some sensitive skins, the skin tissue is heated by radio frequency, so that the originally sensitive skin is stimulated to produce red swelling and other reactions, which is unfavorable for repairing the damaged skin. When the skin returns to an insensitive state, the skin is no longer sensitive to warming.

The temperature module is configured to output a lower temperature in the first mode than in the second mode. When the user is in a skin sensitive state, the first mode is used, the skin care device releases radio frequency and cold energy in the first mode, when the radio frequency acts on the skin, the radio frequency can promote epithelial cell proliferation and heat the skin, and the cold energy can at least offset part of the heat of the skin, so that the temperature of the skin is reduced, and red swelling of the skin caused by the heat is reduced. When the skin is insensitive, the user uses the second mode, the skin care device releases radio frequency and heat in the second mode, and the skin absorption channel can be promoted to be opened through the heating effect of the radio frequency and the heat, and the skin care product is combined, so that the absorption of the skin care product can be promoted, and further deep repair is realized.

In some embodiments, the temperature output by the heat exchange unit 11 in the first mode is 10-20 ℃ for ice compress. When the temperature output by the heat exchange unit 11 is lower than 10 ℃, skin damage can be caused, and the radio frequency cosmetic effect of the radio frequency unit 13 is affected. When the temperature outputted from the heat exchange unit 11 is 20 deg.c, the effect of ice compress is not remarkable.

The following describes how skin damage is caused and the rf cosmetic effect of the heat exchange unit 11 is affected when the temperature of the insulating member 30 is too low:

Studies have shown that when skin temperature is 15 ℃, skin vasoconstriction reaches a maximum, tissue damage can be caused by long-term maintenance of tissue temperature at 15 ℃, and nerve damage can be caused below 15 ℃. According to van der waals' law, cryotherapy, i.e. cold compress, reduces biochemical reactions in time units, thereby slowing down cellular metabolism. The first modification of the vascular system involves surface vasoconstriction followed by reflex systemic vasoconstriction. Vasoconstriction is greatest at 15 ℃. When the skin temperature drops by 15 ℃, contradictory vasodilation occurs due to paralysis of vascular smooth muscle or nerve block of vasoconstrictive nerve fibers. This vasodilation is a defensive mechanism to maintain blood flow at low temperatures. Low temperatures slow down peripheral nerve conduction. It has been demonstrated that for every 1℃decrease in temperature, the peripheral nerve conduction decreases by 2.4 m/s, and at 10℃to 15℃the nerve conduction completely disappears. The effect of cryotherapy on muscle is related to the time of application. When the cryotherapy local temperature is below about 14 ℃, the propagation of action potentials along the autonomic and sensory nerves is impaired (cold-induced nerve loss), leading to contradictory vasodilation and paresthesia. In the embodiment of the application, the target temperature of cold compress is about 30 min in 15-25 ℃ from the safety aspect, and the cold compress can be monitored in real time through a temperature sensor, so that the safety is ensured. If the temperature is selected in the range of 0-10 ℃, the corresponding cosmetic duration should be considered, so as to avoid nerve damage and discomfort caused by cryotherapy.

It should be noted that, although the lowest temperature output by the heat exchange unit 11 in the first mode is 10 ℃, the temperature of the skin may be higher than 15 ℃ because the heat exchange unit 11 is not in direct contact with the skin, which is limited by the influence of the heat exchange efficiency.

The temperature output by the heat exchange unit 11 in the second mode is 40-50 ℃ for hot compress. When the temperature output by the heat exchange unit 11 is lower than 40 ℃, the temperature is close to the skin temperature of a human body, the hot compress effect is not obvious, and the radio frequency beauty effect of the radio frequency unit 13 is affected. When the temperature output from the heat exchange unit 11 is 50 deg.c, the temperature is easily too high to burn the skin. The temperature of the output of the heat exchange unit 11 in the second mode is preferably 45 ℃.

In some embodiments, the rf frequencies output by the rf unit 13 in the first mode and the second mode are the same, so that the repair degree of the rf unit 13 to the skin is consistent when the rf unit 13 works, and the complexity of the control of the rf unit 13 by the control module 40 can be reduced. For example, the radio frequency can be 6.78 MHz, 13.56 MHz, 27.12 MHz, 40.68 MHz or 54.24MHz, so that the radio frequency is higher, and can induce larger displacement current at deeper skin positions to provide larger repair energy, thereby improving the repair effect.

In some embodiments, the radio frequency is a short wave radio frequency having a frequency of 27.12 Mhz.

Referring to fig. 3, in some embodiments, the waveform of the short wave radio frequency is a sine wave. I.e. the short wave form of a single pulse is a sine wave with minimal harmonic components. The research shows that the sine wave of 27.12MHZ has better effect.

In some embodiments, the short wave radio frequency has a pulse frequency in the range of 5Hz to 600 Hz. It should be noted that the radio frequency can form a rapidly varying pulsed electromagnetic field, the growth factor is generated depending on the calcium and the calmodulin, and the pulsed magnetic field can accelerate the binding of Ca2+ to the calmodulin. The CaM/cNOS/NO signal pathway can down-regulate Interleukin (IL) -1 beta, induce inflammation reduction and accelerate wound repair. The pulsed magnetic field was also found to significantly reduce IL-17A (33%) and MMP2 gene expression in IL-1 a-induced NP cells and nuclear factor kappa B (NF-kB) (11%) in AF cells. The effective short wave radio frequency pulse frequency range is between 5Hz and 600Hz under the influence of Ca/CaM receptor response frequency of a Ca < 2+ > signal receptor in the intracellular signal transduction process.

With continued reference to FIG. 3, in some embodiments, the duty cycle of the RF is 2% -10%, i.e., the duty cycle of the pulse frequency of the short wave RF is 2% -10%. The duty cycle is 2% -10% of the ratio of the duration corresponding to the radio frequency energy shown in fig. 3 to the duration corresponding to the radio frequency energy output period. The pulse frequency duty ratio of the short-wave radio frequency is lower than 10%, so that cell overheating caused by cell energy accumulation can be effectively avoided, cells can transfer heat to the periphery in the time of stopping the radio frequency, and overheating and burn conditions can be effectively avoided. If the pulse frequency duty cycle of the short wave radio frequency is higher than 10%, the cells overheat and burn the skin of the user. The pulse frequency duty ratio of the short wave radio frequency is higher than 2%, so that cells can receive relatively more radio frequencies, and the cell regeneration promoting effect is relatively obvious. If the pulse frequency duty ratio of the short wave radio frequency is lower than 2%, the regeneration promoting effect on cells is not obvious. Preferably, the duty cycle of the sine wave is 4%.

In some embodiments, in a single pulse, the sine wave is a continuous waveform, if the sine wave with the duty ratio of 4% is split, the displacement current acts on the cells discontinuously, the energy accumulation of the cells is poor, the temperature rise efficiency of the cells is low, and the effect is also affected.

In some embodiments, the effective rf time of the rf unit 13 output in the first mode is less than the effective rf time of the rf unit 13 output in the second mode. Since the duty cycle of the radio frequency unit 13 is not 100%, i.e. the radio frequency unit 13 is not continuously operated, the effective radio frequency time of the radio frequency unit 13, i.e. the total operating time of the radio frequency unit 13.

The user uses the first mode when the skin is in a sensitive state, and by properly reducing the effective output time of the radio frequency unit 13 in the first mode, the skin irritation can be reduced. When the skin is in an insensitive state, the user uses the second mode, and the skin is insensitive to temperature rise, so that the effective output time of the radio frequency unit 13 in the second mode can be increased, and the repair speed of the skin can be increased.

In some embodiments, the skin care device further has a third mode, the skin care device releasing the radio frequency when in the third mode. The heat exchange unit 11 stops working, and neither cold nor heat is released.

The user may choose the third mode to care when the user's skin transitions between the sensitive and insensitive states. The skin can bear the temperature rise brought by radio frequency in the transition state, but cannot bear the additional heat temperature rise, and the skin can be effectively promoted to recover by repairing the skin at normal temperature through the independent radio frequency. It will be appreciated that the radio frequency released by the skin care device in the third mode is preferably between the radio frequency released by the skin care device in the first mode and the radio frequency released by the skin care device in the second mode.

In some embodiments, the skin care device operates in the first mode, the third mode, and the second mode sequentially in the time dimension. That is, as the skin is restored from the sensitive state to the transitional state and the insensitive state, the user can sequentially perform the care using the first mode, the third mode, and the second mode. The three modes correspond to three states of the skin so as to meet the nursing requirements of different states of the skin.

Referring to fig. 2, in some embodiments, the cosmetic energy includes light, the skin care device further includes a light emitting unit 12, the light emitting unit 12 is disposed in the housing 20 or disposed on a surface of the housing 20, the light emitting unit 12 is configured to output the light, the light emitting unit 12 is electrically connected to the control module 40, and the control module 40 can drive the light emitting unit 12 to operate.

The skin care device outputs light when operating in at least one mode of operation, e.g. the skin care device outputs light when in the first mode. Alternatively, the skin care device outputs light when operating in any of the modes of operation, such as when the skin care device outputs light in the first mode, the second mode, and the third mode. Phototherapy can regenerate cytokines by activating cells, thereby achieving the effect of repairing skin aging, effectively removing wrinkles, enabling the skin to be fine, smooth and glossy, and enabling the skin to be younger.

In some embodiments, the light emitted by the light emitting unit 12 includes at least one of red light, green light, blue light, and yellow light. The red light can promote skin cell regeneration, promote blood circulation, relieve acne mark scars, and relieve pain for allergic dermatitis. The green light can treat pigment or allergic skin diseases, can well pacify and stabilize skin, and can improve superficial wrinkles, blackheads, acne and the like of the skin caused by mental stress by simultaneously carrying out green light irradiation. The blue light has the effect of rapidly inhibiting inflammation, can kill propionibacterium acnes, superficial fungi and the like, and has better treatment effect on folliculitis and the like caused by propionibacterium acnes, superficial fungi and the like. The yellow light can effectively prevent skin red marks and erythema and relieve red swelling.

Referring to fig. 2, in some embodiments, the skin care device further includes a switch button 50 and a mode button 60, the switch button 50 is used to control the skin care device to be turned on or off, and the mode button 60 is used to switch the operation mode when the skin care device is turned on. The switch key 50 and the mode key 60 may be disposed on the surface of the housing 20, and the switch key 50 and the mode key 60 are electrically connected to the control module 40.

In some embodiments, the skin care device outputs a vibration at intervals to alert the user to change the care area. The vibration function may be achieved by a vibration motor.

In some embodiments, the skin care device further comprises an insulating member 30, the insulating member 30 having insulating properties, i.e. being non-conductive. The insulator 30 is connected to the housing 20, and the insulator 30 and the housing 20 together define a mounting chamber 20a. The mounting cavity 20a has an opening 20b, the insulator 30 covers the opening 20b, and other components of the skin care device, such as the radio frequency unit 13 and the light emitting assembly, can be mounted within the mounting cavity 20a. Exemplary ways of connecting the insulating member 30 to the housing 20 include, but are not limited to, at least one of bonding, clamping, and screwing, which is not limited in this embodiment.

The rf unit 13 is a main component for generating rf cosmetic effect, and the rf unit 13 is installed in the installation cavity 20a. The rf unit 13 is disposed in the mounting cavity 20a corresponding to the insulating member 30, and illustratively, the rf unit 13 may be attached to an inner side surface of the insulating member 30 facing the mounting cavity 20a, and the rf unit 13 may be disposed opposite to and spaced from an inner side surface of the insulating member 30 facing the mounting cavity 20a, so long as the insulating member 30 is capable of spacing the rf unit 13 from the skin.

Specifically, since the insulator 30 insulates the rf unit 13 from the skin of the human body, the rf unit 13 can construct a capacitor model between the rf unit 13 and the skin of the human body when the short-wave rf generator is operated, i.e., the rf unit 13 is supplied with the rf signal.

Referring to fig. 4, in some embodiments, the rf unit 13 includes at least a first electrode 131 and a second electrode 132 that are spaced apart and insulated from each other, and the first electrode 131 and the second electrode 132 are installed in the installation cavity 20 a.

In the related art, a resistor model is generally adopted to realize radio frequency beauty, that is, two radio frequency electrodes of a radio frequency skin care device are simultaneously contacted with skin of a user, when high-frequency alternating current is provided for the two radio frequency electrodes, current flows from one radio frequency electrode to the other radio frequency electrode through skin, through modeling, the skin can be equivalent to a resistor or a combination of the resistor and a capacitor, and has specific impedance, continuous current directly penetrates through the skin surface layer through the radio frequency waves, so that the aim of heating collagen tissues and cell tissues is fulfilled, and the beauty effect is achieved.

Unlike the resistor model, the skin care device of the present embodiment employs a capacitor model to achieve radio frequency cosmetic, i.e., direct contact with the skin through the insulator 30, while the first electrode 131 and the second electrode 132 are disposed within the mounting cavity 20a, the insulator 30 spacing the first electrode 131 and the second electrode 132 from the skin. When high-frequency alternating current is supplied to the first electrode 131 and the second electrode 132, a third electrode opposite in polarity to the first electrode 131 is induced to the skin of the portion opposite to the first electrode 131, and the first electrode 131 and the third electrode are separated by the insulating member 30, and the whole can be equivalent to a capacitor; and the same is true. The portion of the skin opposite the second electrode 132 induces a fourth electrode of opposite polarity to the second electrode 132, the second electrode 132 being separated from the fourth electrode by the insulator 30, and the whole being equivalently another capacitor. When alternating current is supplied to the first electrode 131 and the second electrode 132, one of the first electrode 131 and the second electrode 132 is a positive electrode, and the other is a negative electrode, and thus the limits of the third electrode and the fourth electrode are also opposite, and a current flows from the third electrode as the positive electrode to the fourth electrode as the negative electrode, or from the fourth positive electrode as the positive electrode to the third electrode as the negative electrode, so that an induced current is induced between the third electrode and the fourth electrode.

In addition, the skin is divided into a basal layer, a thorn layer, a granular layer, a transparent layer and a horny layer from inside to outside, and the skin barrier is generally referred to as the horny layer of the epidermis, which is a barrier for reducing the passive diffusion of moisture from the skin and also serves as a barrier for preventing other molecules (including irritants) from entering the skin. The skin barrier is primarily formed as a "brick wall" structure by the attachment of keratinocytes and intercellular lipids, the tight attachment of which is critical to maintaining the integrity of the skin barrier. There are studies showing that: the main cause of sensitive muscles is an impaired skin barrier function, i.e. a weak or defective "brick wall" structure. On the one hand, impaired skin barrier function, accelerated transdermal moisture loss and loss of skin nutrients, which lead to a significant decrease in ceramide content, while upregulation of sphingolipid levels is associated with reduced skin barrier stability; on the other hand, the fragile skin barrier can enhance the penetration effect of the irritant or allergen, the nerve endings are not fully protected, and deeper skin is exposed to microorganisms and external stimulus, so that the local inflammatory state of the skin is induced, and symptoms such as redness, itching, burning and stinging occur. And studies have shown that: the impaired integrity of the skin barrier increases the incidence of atopic dermatitis, and the risk of allergy in individuals with sensitive skin is also 5 times higher.
