The invention discloses an invisible flexible closed transdermal repair device, and belongs to the technical field of skin care devices. The device is formed by compounding an inner medicine contact layer, a middle flexible closed fitting layer and an outer simulation invisible shading layer, and can be applied to any skin part of the whole body of a human body. The inner layer is loaded with skin repairing active ingredients, so that continuous slow release and transdermal permeation of the medicine are realized; the middle layer is made of a flexible moldable material to form a closed microenvironment, so that water and medicine are locked, and the dry side effect of the medicine is counteracted; the outer layer has the full-shading performance and the skin simulation appearance, visual invisibility can be achieved, photosensitive component medicine can be protected to stably take effect in the daytime, and meanwhile cosmetic modification is supported. The device can automatically maintain skin micro-moisture balance, improves wearing comfort and long-term tolerance, is compatible with multi-scene hidden wearing such as daily make-up and social contact while efficiently repairing the skin, and is high in universality and wide in application prospect.

Description

Technical Field

[0001] This invention belongs to the technical field of skin repair, transdermal absorption and flexible fit care devices, specifically involving a flexible repair device that can be used all over the body, is invisible to the skin, locks in medication, provides light protection, and automatically maintains the skin's micro-moisture balance. Background Technology

[0002] Existing skin treatment and care products generally suffer from the following drawbacks: 1. Topical medications are prone to evaporation and friction-induced detachment, resulting in low drug utilization and short duration of action, making sustained repair difficult; 2. Most highly effective skin repair ingredients are photosensitive substances, suitable only for nighttime use and unable to provide stable daytime efficacy; 3. Mainstream repair medications easily cause skin dryness, tightness, stinging, and other discomforts, leading to poor long-term tolerance; 4. Traditional occlusive dressings can cause excessive skin moisture and heat, while open application cannot maintain stable efficacy and achieve a balance between dryness and moisture; 5. There is a lack of integrated repair devices that are invisible, do not interfere with daily makeup and social activities, and are compatible with all parts of the body. This invention effectively solves all the above technical problems and fills a gap in the industry. Summary of the Invention

[0003] I. Purpose of the Invention: To address the shortcomings of existing technologies, this invention provides a transdermal repair device that is invisible, provides closed drug delivery, offers full light protection, can be used on any part of the body, and can automatically maintain the skin's micro-moisture balance, counteract the dryness and irritation of drugs, and improve wearing comfort. This device achieves efficient, gentle, discreet, and long-term stable skin barrier repair and health reconstruction.

[0004] II. Technical Solution: An invisible flexible closed transdermal repair device, comprising a three-layer composite structure: an inner drug contact layer, a middle flexible sealing and bonding layer, and an outer simulated invisible light-blocking layer. 1. Inner layer: Drug contact layer, directly adhering to the skin surface, can load effective skin-repairing ingredients, forming a stable and uniform drug film to achieve continuous sustained release and efficient transdermal penetration of the drug. 2. Middle layer: Flexible sealing and bonding layer, made of a soft, malleable, highly conforming, and borderless paste or gel-like material, can adhere tightly to the skin surface without lifting, falling off, or leaving pressure marks, forming a sealed microenvironment, reducing drug loss, and significantly prolonging the duration of drug action. 3. Outer layer: Simulated invisible light-blocking layer, possessing a color, texture, and feel highly consistent with human skin, achieving visual invisibility and allowing direct makeup application; it also has full light-blocking performance, effectively protecting the stability and inactivation of the inner layer's photosensitive components.

[0005] III. Core Innovation Highlights: This device uses a middle flexible sealing layer and an outer simulated invisible light-blocking layer to work together to form a closed water-locking structure, creating a gentle, stable, and long-lasting micro-humid environment between the skin and the medication. This automatically counteracts the dryness, tightness, stinging, and other irritations caused by the repair medication, keeping the skin in the optimal balance of not being dry or cracked, not being stuffy or overly moisturized, significantly improving wearing comfort and long-term tolerance.

[0006] IV. Working Principle: The inner drug contact layer continuously releases active ingredients to achieve antibacterial, repair, and thickening of the skin barrier; the middle flexible sealing layer seals and locks in the drug and the skin's own moisture, improving drug absorption efficiency; the outer simulated invisible light-blocking layer achieves invisible appearance and full light-blocking protection, ensuring that photosensitive ingredients can take effect safely during the day; the three-layer structure works synergistically to form a stable micro-humidity balance repair microenvironment, completing deep skin repair without being noticed and without affecting daily life.

[0007] Beneficial effects: 1. Significantly extended drug action time, improved utilization rate, and multiplied repair effect; 2. Overcomes limitations of photosensitive ingredients, achieving safe, stable, and continuous efficacy during the day; 3. Automatically maintains skin's micro-moisture balance, effectively counteracting drug dryness and irritation, comfortable to wear without tightness or stinging; 4. Gentle and controllable enclosed environment, does not cause skin irritation or harmful microbial growth, suitable for long-term use; 5. Invisible skin-fitting design, can be worn discreetly during makeup, social, and work scenarios, without affecting appearance; 6. Suitable for use on any part of the body, highly versatile, and widely applicable; 7. Long-term use can thicken the skin barrier, strengthen skin resistance, and reduce sensitivity, redness, and problem recurrence.

[0008] Scope of application: This device is suitable for the repair and care of skin, barrier reconstruction, antibacterial maintenance and skin texture improvement on any part of the body, without any site restrictions.

[0009] Detailed implementation method: 1. Clean the target skin area and wipe until completely dry; 2. Apply the device flat to the skin surface, gently press the edges to ensure a tight fit without gaps; 3. Makeup, concealer, and other embellishments can be applied to the outer layer as usual, maintaining a natural and invisible appearance; 4. During wear, the device automatically maintains a micro-moisture balance, continuously exerting a occlusive transdermal repair effect; 5. After use, gently remove the device and clean the skin. Attached image description: Figure 1 This is a schematic diagram of the cross-sectional structure of an invisible, flexible, closed transdermal repair device. The simulated invisible light-blocking layer 1 is the outermost layer, achieving both appearance invisibility and light-blocking protection; the flexible sealed adhesive layer 2 is the middle layer, forming a closed microenvironment and locking in moisture; the drug contact layer 3 is the inner layer, directly contacting the human skin layer 4 and loading repair ingredients.
