Description

Technical Field

[0001] This invention belongs to the technical fields of cosmetics, skin care products, medical cold compress materials and biofunctional materials. Specifically, it relates to a two-liquid system, a mask product that forms a film on the skin surface in situ under low temperature conditions, and achieves instant invisible firming and wrinkle removal through physical support, as well as its preparation process and usage method. Background Technology

[0002] With rising consumer demand, the market for facial anti-wrinkle, firming, and lifting skincare products and medical aesthetic products continues to expand. Existing technologies and products have the following significant shortcomings: 1. Traditional sheet masks and cream masks are pre-formed or simply coated systems, unable to form a continuous, stable, and highly elastic three-dimensional film on the skin surface. They lack physical support and immediate wrinkle-removing capabilities, only providing basic moisturizing and nutrient supply; 2. Existing spray skincare products only offer hydration, soothing, and makeup-setting functions, unable to trigger in-situ cross-linking reactions, and therefore cannot form a long-lasting firming film, resulting in weak and short-lasting wrinkle-removing effects; 3. Existing film-forming skincare products often rely on high-temperature curing, strong chemical cross-linking agents, organic solvents, or film-forming aids, which are highly irritating and prone to causing allergies, making them unsuitable for long-term use on delicate facial skin; 4. Market products cannot achieve the synergistic effect of low-temperature, gentle, food-grade raw materials, rapid in-situ film formation, and invisible physical wrinkle removal, leaving significant technological gaps in the areas of dual-component triggering, low-temperature cross-linking, and seamless lifting. Based on the above pain points, the market urgently needs a safe, gentle, efficient, convenient, invisible, and scarless instant wrinkle removal technology and product. Summary of the Invention

[0003] 1. Purpose of the invention: The present invention aims to overcome the shortcomings of the prior art and provide a two-component low-temperature in-situ film-forming invisible physical anti-wrinkle mask, achieving the following objectives: (1) Under the low temperature and mild conditions of ≤40℃, it achieves rapid, uniform and stable in-situ cross-linking film formation on the skin surface; (2) It uses safe and biodegradable raw materials, without irritation, heavy metals and strong chemical cross-linking agents, and is suitable for long-term use on all types of skin; (3) It forms a transparent, thin, highly elastic and highly adhesive invisible film layer, which achieves instant wrinkle smoothing and contour tightening through pure physical support and traction; (4) It is flexible and convenient to use, can be sprayed or applied, and forms a film quickly and without leaving a trace, without affecting daily activities, makeup and skin care; (5) The preparation process is simple, the cost is controllable, and it is suitable for large-scale industrial production and market popularization.

[0004] 2. Technical Solution: .1 Product Composition: This invention adopts a two-component independent packaging system, consisting of Liquid A (film-forming matrix liquid) and Liquid B (crosslinking trigger liquid). The two components are stored separately and not mixed before use. Liquid A components (mass percentage): Film-forming matrix 10%–30%, humectant 2%–10%, stabilizer 0.1%–2%, deionized water balance. Liquid B components (mass percentage): Crosslinking trigger 0.1%–3%, humectant 1%–8%, deionized water balance. .2 Raw Material Selection: The film-forming matrix is ​​selected from one or more of natural polymers, proteins, polypeptides, polysaccharides, and water-soluble polymers, including but not limited to bovine casein, ovalbumin, collagen, soy protein, gelatin, hyaluronic acid, carboxymethyl cellulose, polyglutamic acid, etc. The crosslinking trigger is selected from one or more of ionic crosslinking agents, pH adjusters, and mild enzyme preparations, including but not limited to calcium chloride, glucono-delta-lactone, citric acid, ginger protease, etc. The humectant is selected from one or more of glycerin, propylene glycol, sodium hyaluronate, panthenol, and betaine. The stabilizer is selected from one or more of xanthan gum, hydroxyethyl cellulose, and guar gum. 3 Preparation method: (1) Preparation of solution A: Add the film-forming matrix, humectant, and stabilizer to deionized water in sequence, stir until completely dissolved, filter to remove bacteria, and keep warm at ≤40℃ for later use; (2) Preparation of solution B: Add the crosslinking trigger and humectant to deionized water, stir until completely dissolved, filter to remove bacteria, and keep warm at ≤40℃ for later use; (3) Fill solutions A and B into separate containers, seal and store in the dark. 4. Instructions for use: Cleanse your face and keep your skin slightly damp. Apply liquid A evenly to your face, then apply liquid B evenly over it. You can alternate between liquids A and B to enhance the strength and adhesion of the film. Leave it on for 30 seconds to 5 minutes. The two components will come into contact with each other on the skin surface and undergo in-situ cross-linking, automatically forming a transparent, elastic, and invisible firming film. The film does not need to be washed off and makeup can be applied directly, achieving multiple effects such as instant wrinkle removal, moisturizing, and protection. Application methods include spraying, smearing, brushing, and rolling.

[0005] 3. Film-forming principle: Upon contact with the cross-linking trigger in solution B, the film-forming matrix molecules in solution A rapidly undergo molecular entanglement, ionic cross-linking, hydrogen bonding, or mild structural reorganization under low-temperature and mild conditions, forming a continuous, dense, and highly elastic three-dimensional network film structure. This film layer highly adheres to the skin's surface texture and pores, and through physical traction, support, and tightening, it smooths and lifts wrinkles, fine lines, and sagging areas, achieving immediate and invisible wrinkle removal. The entire process requires no high temperature, no strong chemical reagents, and no external energy assistance, making it safe, fast, and stable.

[0006] 4. Beneficial effects: (1) Immediate wrinkle removal: After film formation, physical lifting is achieved immediately, and dry lines, fine lines, nasolabial folds and forehead wrinkles are visibly reduced and smoothed; (2) Completely invisible: The film layer is transparent and thin, adheres to the skin without leaving a trace, without a film feeling, without a mask, without peeling, and cannot be detected by others; (3) Extremely safe: Low temperature and mild system, safe and biodegradable raw materials, no irritation, no alcohol, no fluorescent agents, no harmful cross-linking agents; (4) Flexible use: Can be sprayed or applied, extremely simple operation, quick film formation, non-sticky, no pilling, and can be applied directly to makeup; (5) Multi-effect: Combines the functions of firming mask, makeup base, invisible protection, long-lasting moisturizing, and physical anti-wrinkle; (6) Simple process: The preparation process is mild, the equipment requirements are low, the raw material sources are wide, and it is suitable for large-scale production and popularization.
