These factors accelerate skin cell aging, leading to a haggard and dull complexion. The effects of applying face creams and masks are often less than ideal.

[0003] Among related technologies, LED lights can be used for phototherapy. The mechanism of LED light therapy is mainly based on photobiological regulation. Through the interaction of light of specific wavelengths with biological tissues, a series of biochemical reactions and physiological effects are produced, thereby achieving therapeutic and cosmetic purposes. However, existing home-use repair masks do not have the effect of repairing sensitive skin or age spots. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a repair mask for sensitive skin or melasma, which can be used for phototherapy and can be used at home, improving ease of use and effectively repairing sensitive skin and melasma.

[0006] According to this invention, the repair mask uses multiple LED beads to emit visible and infrared light for phototherapy on the user's face. This helps repair sensitive skin and improve age spots, thus enhancing the mask's cosmetic effect. Furthermore, the high light density emitted by the LED beads increases the face's absorption capacity, further improving the repair and improvement effects. Additionally, the mask's compact size and ease of use allow for repeated use as needed, increasing flexibility. Moreover, it can be used at home, eliminating the need for outings and enhancing user convenience.

[0007] According to some embodiments of the present invention, the λ further satisfies: 580nm≤λ≤850nm.

[0009] According to some embodiments of the present invention, ρ further satisfies: 80%≤ρ≤100%.

[0010] According to some embodiments of the present invention, the repair mask has at least a switchable first mode, a second mode, and a third mode. In the first mode, the wavelength of the light emitted by the LED is λ1, wherein λ1 satisfies: 630nm≤λ1≤1000nm; and / or, in the second mode, the wavelength of the light emitted by the LED is λ2, wherein λ2 satisfies: 500nm≤λ2≤1064nm; and / or, in the first mode, the wavelength of the light emitted by the LED is λ3, wherein λ3 satisfies: 500nm≤λ3≤800nm.

[0011] According to some embodiments of the present invention, in the first mode, λ1 is selected from at least one of 630nm, 660nm, 810nm and 830nm; and / or, in the second mode, λ2 is selected from at least one of 505nm, 590nm, 630nm, 810nm and 830nm; and / or, in the third mode, λ3 is 590nm.

[0012] According to some embodiments of this utility model, the light power density emitted by the lamp bead is I, and the irradiation time is T, wherein I and T respectively satisfy: 5mw / cm 2 ≤I≤20mw / cm 2 , 10min≤T≤20min.

[0013] According to some embodiments of this utility model, I and T further satisfy: I = 10 mw / cm 2 T=10min.

[0014] According to some embodiments of the present invention, the light panel has a first region, a second region, and a third region.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0018] Figure 1 This is a schematic diagram of a repair mask according to an embodiment of the present utility model.

[0019] Figure label:

[0020] 100. Repair mask;

[0021] 1. The mask itself. Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 This invention describes a repair mask for sensitive skin or melasma according to an embodiment of the present invention.

[0023] like Figure 1 As shown, the repair mask for sensitive skin or melasma according to an embodiment of the present invention includes a mask body 1 and a light panel (not shown).

[0024] Specifically, a light panel is mounted on the face mask body 1, and the light panel is equipped with multiple LED beads (not shown in the figure). The multiple LED beads emit visible light and / or infrared light. The light emitted by the LED beads is suitable for illuminating the user's face for repair. The wavelength of the light emitted by the LED beads is λ, and the optical density is ρ, where λ and ρ satisfy: 500nm≤λ≤1200nm and 50%≤ρ≤100%, respectively. In the description of this utility model, "multiple" means two or more.

[0025] For example, the light panel is housed within the mask body 1. The arrangement of the LEDs on the light panel includes the following scenarios: First, multiple LEDs emit visible light. Second, multiple LEDs emit infrared light. Third, multiple LEDs emit both visible and infrared light. After the user wears the repair mask 100, the mask 100 is close to the user's face, and the light emitted by the multiple LEDs on the light panel is suitable for passing through the mask body 1 and illuminating the user's face.

[0026] This setup allows the Repair Mask 100 to perform phototherapy. The specific wavelengths emitted by the LED beads irradiate the user's face, interacting with the facial tissues to produce a series of biochemical reactions and physiological effects, thereby achieving therapeutic and cosmetic purposes. Furthermore, the visible and infrared light emitted by the LED beads covers a wavelength range of 500nm-1200nm, effectively repairing sensitive skin and improving age spots, thus enhancing the repair mask 100's effectiveness in repairing and improving the user's face. Additionally, the light density ρ emitted by the LED beads satisfies the condition of 50% ≤ ρ ≤ 100%, indicating a reasonable setting and high light density. This enhances the user's facial absorption capacity, further improving the repair mask 100's effectiveness in repairing and improving the user's face. It also improves the uniformity of the output. Moreover, the Repair Mask 100's small size and easy portability make it convenient to use, allowing users to reuse it multiple times as needed, increasing its flexibility and improving the user experience. Moreover, it can be used anywhere without needing to go out, improving user convenience. But it's not limited to that. It should be noted that the Repair Mask 100 can not only repair sensitive skin and improve age spots, but also deeply soothe and repair sensitive skin, brighten skin, tighten skin, and reduce wrinkles, achieving different beauty effects.

[0027] According to the repair mask 100 of this utility model, multiple LED beads on the repair mask 100 emit visible and infrared light to perform phototherapy on the user's face, thereby repairing sensitive skin and improving melasma, thus enhancing the cosmetic effect of the repair mask 100 on the user's face. Furthermore, the high light density emitted by the LED beads increases the face's ability to absorb light, further enhancing the repair and improvement effect of the repair mask 100 on the user's face. In addition, the repair mask 100 has a small structure, making it easy to use and allowing users to use it multiple times as needed, increasing its flexibility. Moreover, it can be used at home without needing to go out, improving user convenience.

[0028] According to some embodiments of this utility model, λ further satisfies: 580nm ≤ λ ≤ 850nm. Therefore, by combining the wavelengths λ of multiple LED beads within the range of 580nm-850nm, various different working modes can be achieved, allowing users to choose the working mode of the repair mask 100 according to their needs, thus improving the flexibility and applicability of the repair mask 100. Furthermore, considering the divergence angle and scattering function of the LED beads, the distance between the LED beads and the user's face is L, where L satisfies: 0.2mm ≤ L ≤ 20mm, facilitating distance selection based on irradiation conditions. Additionally, the shell on the side of the mask body 1 that contacts the user is made of silicone, and the mask body 1 also includes a thermoplastic polyurethane elastomer (TPU) component, with the lamp plate located between the silicone component and the thermoplastic polyurethane elastomer component. The repair mask 100 is a contact mask; different positions on the side of the mask body 1 facing the user are at the same distance from the corresponding skin, improving the consistency of the repair effect.

[0029] According to some embodiments of this utility model, λ is selected from at least one of 590nm, 630nm, and 830nm. Thus, when λ is 590nm, the LED emits yellow light; when λ is 630nm, the LED emits red light; and when λ is 830nm, the LED emits infrared light. The three types of light emitted by multiple LEDs work together to achieve various working modes of the repair mask 100, thereby ensuring the applicability of the repair mask 100. For example, when irradiated with yellow light of wavelength 590nm alone, the working mode is whitening and fading spots (i.e., GLOW). Or, when irradiated with yellow light of wavelength 590nm first, followed by irradiation with infrared light of wavelength 830nm, the working mode is special protection and restoration light (i.e., CURE). Or, when irradiated with red light of wavelength 630nm first, followed by irradiation with yellow light of wavelength 590nm, the working mode is reddening and fading marks (i.e., SOOTHE). Alternatively, when irradiated with red light of 630nm wavelength and infrared light of 830nm wavelength simultaneously, the working mode is repair and tightening (i.e., FIRM). But it is not limited to this.

[0030] According to some embodiments of this utility model, ρ further satisfies: 80%≤ρ≤100%. This setting further increases the light density emitted by the lamp beads, thereby further improving the user's facial absorption capacity of light, and thus improving the ability of the repair mask 100 to perform light therapy and repair on the user's face.

[0031] According to some embodiments of the present invention, the repair mask 100 has at least a switchable first mode, a second mode, and a third mode. In the first mode, the wavelength of the light emitted by the LED is λ1, wherein λ1 satisfies: 630nm≤λ1≤1000nm; and / or, in the second mode, the wavelength of the light emitted by the LED is λ2, wherein λ2 satisfies: 500nm≤λ2≤1064nm; and / or, in the first mode, the wavelength of the light emitted by the LED is λ3, wherein λ3 satisfies: 500nm≤λ3≤800nm.

[0032] For example, the Repair Mask 100 has the following modes: First, the Repair Mask 100 switches to Mode 1. Second, the Repair Mask 100 switches to Mode 2. Third, the Repair Mask 100 switches to Mode 3. Fourth, the Repair Mask 100 switches to both Mode 1 and Mode 2 simultaneously. Fifth, the Repair Mask 100 switches to both Mode 1 and Mode 3 simultaneously. Sixth, the Repair Mask 100 switches to both Mode 2 and Mode 3 simultaneously. Seventh, the Repair Mask 100 switches to Mode 1, Mode 2, and Mode 3 simultaneously. With this setup, in Mode 1, the light emitted by the LED beads has a wavelength λ1 in the range of 630nm-1000nm (which is also the fundamental wavelength of problem skin). When this light shines on the user's face, it can eliminate inflammatory factors in the user's face, thus repairing skin sensitivity and allergies. In Mode 2, the light emitted by the LED beads has a wavelength λ2 in the range of 500nm-1064nm. When this light shines on the user's face, it can inhibit pigmentation in the skin, thus improving melasma. In the third working mode, the light emitted by the LED beads has a wavelength λ3 in the range of 500nm-800nm, which can inhibit vascular hyperreactivity and repair sensitive skin. This allows different modes to exert different effects to achieve cosmetic results, thereby improving the user experience.

[0033] It should be noted that both the first and third modes are for repairing sensitive skin, but their mechanisms of action differ. Based on medical theory, light wavelengths above 600nm have a photobiostimulatory effect, with advantages including diffused efficacy, showing effects even in untreated areas, and the effects lasting 1 to 2 days (depending on irradiation time and cumulative light power density). Light wavelengths below 700nm, through the photoreceptor's luminescent clusters, have a photochemical effect, with the advantage of immediate results. Combining optical and photobiostimulatory effects solves the problems of immediate and long-lasting effects, as well as the issues of light uniformity and untreated areas.

[0034] According to some embodiments of the present invention, in a first mode, λ1 is selected from at least one of 630nm, 660nm, 810nm and 830nm; and / or, in a second mode, λ2 is selected from at least one of 505nm, 590nm, 630nm, 810nm and 830nm; and / or, in a third mode, λ3 is 590nm.

[0035] With this setup, in the first mode, when the light wavelength λ1 of the LED is selected from at least one of 630nm, 660nm, 810nm, and 830nm, the light treatment of the repair mask 100 is further biased towards eliminating inflammatory factors, thereby more effectively repairing sensitive skin. In the second mode, when the light wavelength λ2 of the LED is selected from at least one of 505nm, 590nm, 630nm, 810nm, and 830nm, the light treatment of the repair mask 100 is further biased towards inhibiting pigmentation function, thereby more effectively improving melasma. In the third mode, when the light wavelength λ3 of the LED is 590nm, the light treatment of the repair mask 100 is further biased towards inhibiting vascular hyperreactivity (i.e., reducing redness), thereby more effectively repairing sensitive skin.

[0036] According to some embodiments of this utility model, the light power density emitted by the lamp bead is I, and the irradiation time is T, wherein I and T respectively satisfy: 5mw / cm 2 ≤I≤20mw / cm 2 The settings are 10min ≤ T ≤ 20min. This configuration, combined with different wavelengths of light at varying power densities and irradiation times, allows for different operating modes to achieve various repair effects. This enables targeted repair and improvement of different users' skin problems, enhancing the performance of the Repair Mask 100. Furthermore, it also increases energy output. For example, the Repair Mask 100 has the following operating modes:

[0037] First, the operating mode is CURE (Cure-Enhanced Regeneration), which involves irradiating with 590nm yellow light for 10 minutes, followed by 830nm infrared light for 10 minutes, for a total of 20 minutes. The light emitted by the LED is 10mw / cm². 2 This is to achieve deep soothing and repair of the skin.

[0038] Second, the working mode is red-light fading (SOOTHE). First, it is irradiated with red light at a wavelength of 630nm for 5 minutes, then with yellow light at a wavelength of 590nm for 5 minutes, for a total irradiation time of 10 minutes. The light power emitted by the LED is 10mw / cm². 2 This helps to reduce redness and fade red marks on sensitive skin on a daily basis.

[0039] Third, the working mode is GLOW (whitening and fading spots), using 590nm yellow light alone for 10 minutes, for a total of 10 minutes. The light power emitted by the LED is 10mw / cm². 2 To achieve brighter skin and fade blemishes.

[0040] Fourth, the working mode is FIRM (Firming and Repairing), which uses red light with a wavelength of 630nm and infrared light with a wavelength of 830nm to simultaneously irradiate for 10 minutes, for a total of 10 minutes, to achieve skin tightening and wrinkle reduction. However, it is not limited to this. Furthermore, the light power density I emitted by the LED beads further meets the requirement of 8mw / cm². 2 ≤I≤15mw / cm 2 .

[0041] The user's face was tested using the aforementioned operating mode of the repair mask 100. The frequency of use of the repair mask 100 is as follows:

[0042] Use it 6 days a week, then rest for 1 day.

[0043] CURE working mode: 3 times a week (once every other day, specifically Monday, Wednesday, and Friday). Before use, apply the whitening serum and use the device; after use, apply a moisturizing mask (15 minutes), wash off the mask, and then apply the whitening serum again.

[0044] SOOTHE, GLOW, FIRM working modes: once a week (SOOTHE mode on Tuesdays, GLOW mode on Thursdays, and FIRM mode on Saturdays). Before use, apply the whitening agent and use the instrument (corresponding to the working mode mentioned above); after use, apply the whitening agent.

[0045] The test results are shown in Tables 1-3.

[0047]

[0048] Table 2. Transepidermal water loss rate of facial skin

[0049]

[0050] Table 3. Degree of facial redness

[0051]

[0052] Referring to Table 1, the change rate of facial skin stratum corneum moisture content was greater after using the Repair Mask 100 in conjunction with skincare products, and the change rate after using the Repair Mask 100 in conjunction with skincare products was greater than that after using skincare products alone. Therefore, it can be concluded that the Repair Mask 100 effectively increased the moisture content of the facial skin stratum corneum. Referring to Table 2, the change rate of facial skin transepidermal water loss was smaller after using the Repair Mask 100 in conjunction with skincare products, and the change rate after using the Repair Mask 100 in conjunction with skincare products was less than that after using skincare products alone. Therefore, it can be concluded that the Repair Mask 100 reduced facial skin transepidermal water loss. Referring to Table 3, the change rate of facial skin redness was smaller after using the Repair Mask 100 in conjunction with skincare products, and the change rate after using the Repair Mask 100 in conjunction with skincare products was less than that after using skincare products alone. Therefore, it can be concluded that the Repair Mask 100 reduced facial skin redness. Therefore, combining Tables 1-3, it can be concluded that the Repair Mask 100 has a good improvement and repair effect.

[0053] According to some embodiments of this utility model, I and T further satisfy: I = 10mw / cm 2 T=10min. Therefore, considering both compliance and efficacy, the light power density emitted by the LED bead in the repair mask 100 is 10mw / cm². 2 When the irradiation time is 10 minutes, the Repair Mask 100 has a better effect on repairing sensitive skin and improving melasma, thus improving the user experience.

[0054] According to some embodiments of the present invention, the light panel has a first region, a second region, and a third region. The first region, the second region, and the third region are each in a first mode, a second mode, or a third mode independently. The first region is at least opposite to the user's forehead, the second region is at least opposite to the user's eye area, and the third region is at least opposite to the user's cheek.

[0055] For example, the first area on the light panel can operate independently in one of three modes: mode 1, mode 2, or mode 3. The second area can operate independently in one of three modes: mode 1, mode 2, or mode 3. The third area can operate independently in one of three modes: mode 1, mode 2, or mode 3. Multiple LEDs in the first area illuminate the user's forehead to repair forehead wrinkles, oil secretion, and redness. Multiple LEDs in the second area illuminate the area around the user's eyes to repair age spots and crow's feet. Multiple LEDs in the third area illuminate the user's cheeks to repair wrinkles (such as nasolabial folds and marionette lines), oil secretion, and redness. This setup allows for targeted repair and improvement of different areas of the user's face, essentially providing customized repair for different skin types. This improves the precision and efficiency of the repair mask 100's treatment of the user's facial skin, offers users multiple options, and enhances the user experience.

[0056] The first, second, and third zones each offer multiple time settings, such as 5 minutes, 10 minutes, 20 minutes, and 25 minutes. Different light source combinations can also be selected for each zone, such as: First, multiple LEDs emitting yellow light to brighten and fade dark spots; second, multiple LEDs emitting red light to refine and brighten the skin; third, multiple LEDs emitting infrared light to repair and strengthen the skin; fourth, multiple LEDs emitting both red and infrared light to firm and reduce wrinkles; fifth, multiple LEDs emitting both red and yellow light to reduce redness and blemishes; sixth, multiple LEDs emitting both yellow and infrared light to control oil and soothe the skin; and seventh, multiple LEDs emitting yellow, red, and infrared light for multi-effect skin rejuvenation.

[0057] The effect of Repair Mask 100 on the relative expression level of IL-1α gene in HaCaT cells was tested, as shown in Table 4 below. Figure 1 As shown,

[0058] Table 4. Effects of Repair Mask 100 on the relative expression level of IL-1α gene in HaCaT cells.

[0059]

[0060]

[0061] Figure 1 Effects of Repair Mask 100 on the relative expression level of IL-1α gene in HaCaT cells

[0062] Combine Table 4 and Figure 1 It was found that when Repair Mask 100 was used in conjunction with skincare products, the relative expression level of the IL-1α gene in HaCaT cells decreased. The lower the relative expression level of the IL-1α gene, the better the inhibitory effect on inflammatory factors in the skin. Furthermore, comparing the relative expression level of the IL-1α gene when Repair Mask 100 was used in conjunction with skincare products with the relative expression level of the IL-1α gene when the skincare products were used alone, effectively demonstrates that Repair Mask 100 can reduce the relative expression level of the IL-1α gene, thereby inhibiting inflammatory responses, reducing the impact on the expression and synthesis of the skin barrier, and reducing nerve sensitivity to repair sensitive skin. It also reduces melanin production by melanocytes, inhibits inflammation and angiogenesis, and reduces UV sensitivity to improve melasma.

[0063] According to some embodiments of this utility model, an eye-viewing hole is formed on the lamp plate, and the minimum distance between the lamp bead and the edge of the eye-viewing hole is d, where d satisfies: 0.5cm ≤ d ≤ 1.0cm. For example, when the minimum distance d between the lamp bead and the edge of the eye-viewing hole is less than 0.5cm, the distance between the lamp bead and the eye-viewing hole is small, and the light emitted by the lamp bead is more likely to shine on the user's eyes, reducing the user's comfort when wearing it. In addition, it also increases the difficulty of installing the lamp bead on the lamp plate. When the minimum distance d between the lamp bead and the edge of the eye-viewing hole is greater than 1.0cm, the distance between the lamp bead and the edge of the eye-viewing hole is large, and the light emitted by the lamp bead cannot shine on the area around the user's eyes, thereby reducing the improvement effect on the area around the eyes. Therefore, by setting the minimum distance d between the lamp bead and the edge of the eye-viewing hole to satisfy: 0.5cm ≤ d ≤ 1.0cm, the setting is reasonable, which can make the light emitted by the lamp bead shine on the area around the user's eyes, repair and improve the area around the eyes, and improve the cosmetic effect of the skin around the eyes. This design also avoids light shining into the user's eyes during use, improving user comfort and safety. Furthermore, it reduces the difficulty of installing the LED beads on the light board, increasing the ease of installation. The minimum distance d between the LED bead and the edge of the eye-shaped through-hole is preferably 0.5cm.

[0064] Other configurations and operations of the repair mask 100 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
