Description

[0001] The invention relates to the cosmetic industry, namely to products for moisturizing facial skin, and can be used in the form of a fabric moisturizing face mask.

[0002] A collagen facial mask and its preparation method are known (CN102138870A). An aqueous solution of collagen with a mass fraction of (1-20%) and an aqueous solution of a modifier with a mass fraction of (0.1-2%) are mixed and reacted at a temperature of 20-60 ° C for 15-45 minutes to prepare a stock solution, and then plasticizers, functional additives and antimicrobial growth agents are added to the stock solution and continue stirring at a temperature of 20-60 ° C for 30-60 minutes to prepare a mixed solution, then pour the mixed solution into a mold and dry at a temperature of 30-60 ° C for 3~10 hours, obtaining a collagen mask.

[0003] Disadvantages:

[0004] - a less elastic and poorly adhering film is formed, which is not comfortable enough to use and may release active ingredients worse due to the use of only collagen as a base;

[0005] - the required homogeneity of functional ingredients in the final product is not ensured due to the lack of a preliminary structuring and swelling stage of the composition.

[0006] A known composition for the manufacture of cosmetics (RU patent for invention RU2752733C1) has moisturizing, sunscreen properties, activates collagen synthesis, contains betulin and / or its derivatives selected from betulinic acid, betulonic acid, allobetulin, betulin diphosphate, lupeol, betulin diacetate, zinc oxide in the form of nanoparticles of 1-500 nm in size, vegetable oils and excipients, which uses a mixture of vegetable fatty oils and vegetable essential oils in a weight ratio of 100: 1 to 5: 1, wherein the vegetable fatty oils selected from: sunflower oil, olive oil, rice oil, almond oil, castor oil, cocoa butter, peach oil, apricot oil, amaranth oil, mustard oil, corn oil, sea buckthorn oil, red palm oil, camelina oil, pumpkin seed oil;and plant essential oils selected from: lavender oil, pine oil, geranium oil, thyme oil, eucalyptus oil, clove oil, tea tree oil, anise oil, and auxiliary substances, in the following ratio of components, wt. %: betulin and / or its derivatives - 0.10-20.00, zinc oxide particles - 0.01-15.00, auxiliary substances - 0.01-5.00, a mixture of vegetable fatty oils and vegetable essential oils - up to 100.00.;

[0007] Disadvantages:

[0008] - high comedogenic potential due to the presence of some vegetable oils (eg castor oil, cocoa butter, red palm oil).

[0009] The closest to the proposed solution is a cosmetic mask (RU Patent for Invention No. 2311169), consisting of a textile material, a sodium alginate composition with biologically active substances distributed within it, water, wherein the composition additionally contains acetic acid collagen, wherein the ratio of acetic acid collagen, alginate, biologically active material and water in the composition in wt. % is 5.4, 0.08, (0.01-0.1), (94.51-94.42), respectively, the textile material is made of non-woven cellulose material, and the composition is on one of the surfaces of the textile material, and the drapeability of the cosmetic mask in a wet state is 78-85%.

[0010] Disadvantages:

[0011] - low concentration of sodium alginate calls into question its ability to act as a thickener and form a stable gel structure to hold other components;

[0012] - too liquid, flowing consistency of the composition, complicating its application due to the high content of water in the composition (over 94 wt.%).

[0013] The essence of the claimed invention is that the use of pectin substances in combination with sunflower lecithin and fish collagen as a structure-forming, moisturizing and regenerating complex makes it possible to obtain a stable homogeneous solution with high technological potential for creating a moisturizing tissue mask.

[0014] The technical result is to expand the range of cosmetic effects of the fabric mask on the skin, increase the ease of use and improve the cosmetic effect due to a tight fit to the relief of the face, uniform transfer of care components to the skin during the entire procedure, as well as preventing premature drying and displacement of the mask due to the elastic texture of the fabric and high adhesion to moisturized skin, which ensures comfortable application and easy removal without delamination of the material.

[0015] The technical result is achieved due to the fact that the method for producing a pectin-containing moisturizing tissue mask for the face consists of pre-mixing low-esterified pectin with fish collagen and sunflower lecithin in a ratio of 1:1:1, adding an aqueous extract of thyme, aloe vera juice and avocado essential oil, subsequent swelling for 30 minutes, after which they are thoroughly mixed until a homogeneous state is formed, then the tissue base is impregnated and packaged in the following ratio of components, % by weight:

[0016] Low-esterified pectin 3 Sunflower lecithin 3 Fish collagen 3 Thyme water extract 80 Aloe vera juice 10 Avocado essential oil 1

[0017] The advantage of the claimed method is the production of a new high-tech pectin-containing moisturizing fabric mask that is easy to use, adheres well to the face without the impregnation dripping, provides smoothness and softness of the facial skin, eliminates the feeling of tightness and reduces visible peeling.

[0018] Pectin substances are natural biopolymers and polysaccharides with a range of functional, technological, and performance properties. Their sorption, antibacterial, water-retaining, and gelling properties are particularly important for cosmetology and dermatology. Pectins, particularly low-esterified ones, actively bind and remove toxins, oxidation products, excess sebum, as well as heavy metal ions and other impurities accumulated in pores from the skin.

[0019] Sunflower lecithin is a complex mixture of natural phospholipids, glycolipids, triglycerides, and a small amount of other lipid compounds, obtained by gentle cold pressing or extraction from sunflower seeds. Unlike soy lecithin, it is valued in the cosmetology and food industries as a hypoallergenic, GMO-free, highly bioavailable emulsifier and effective plasticizer. Its key technological functions are based on the amphiphilic properties of phospholipid molecules, which stabilize heterogeneous systems and, in a biological context, structurally and functionally support skin cell membranes, providing restorative, softening, and anti-inflammatory effects.

[0020] Fish collagen is a type of protein derived from the skin, scales, and bones of marine fish such as cod, salmon, and pollock. It belongs to type I collagen, which is most similar to human collagen and forms the basis of our skin's structure, providing its elasticity and smoothness. In cosmetology, fish collagen is valued for its high bioavailability and ability to stimulate the synthesis of collagen, elastin, and hyaluronic acid in the dermis.

[0021] Thyme water extract is a concentrated extract of biologically active substances obtained from the leaves and flowers of the Thymus vulgaris plant. Rich in thymol, carvacrol, and flavonoids, it has powerful antiseptic, anti-inflammatory, and antioxidant properties. In cosmetology, it is valued as a natural preservative that also soothes irritations and tones the skin, restoring a healthy, matte appearance.

[0022] An infusion of thyme is prepared as follows: place two filter bags (3 g) in a glass or enamel container, pour in 200 ml (1 cup) of boiling water, cover, and let steep for 15 minutes, periodically pressing on the bags with a spoon, then squeeze them out. The volume of the resulting infusion is brought to 200 ml with boiled water.

[0023] Aloe vera juice (Aloe barbadensis Miller) is a complex biogenic hydrogel, the main bioactive component of which is the polysaccharide acemannan, and contains a complex of vitamins, minerals, amino acids and enzymes, which ensures its multifunctional action in cosmetology: high moisturizing properties are due to the ability of polysaccharides to retain water and form a protective occlusive film, reparative and anti-inflammatory effects are associated with the stimulation of collagen synthesis and the inhibition of inflammatory mediators, and antioxidant activity - with the neutralization of reactive oxygen species.

[0024] Avocado essential oil is a fixed or fatty oil obtained by cold pressing from the pulp of the Persea americana fruit. It is distinguished by a high concentration of unsaturated fatty acids (especially oleic acid), squalene, vitamins A, D, and E, and phytosterols. In cosmetology, its role is intensive nourishment, restoration, and strengthening of the skin's lipid barrier. It is suitable for dry, mature, tired, and damaged skin: it deeply softens, combats flaking, improves elasticity, smoothes fine lines, and protects against free radicals, acting as a powerful antioxidant.

[0025] A pectin-containing moisturizing sheet mask for the face is prepared as follows. Low-esterified pectin is pre-mixed with sunflower lecithin and fish collagen in a 1:1:1 ratio. A portion of the aqueous thyme extract, aloe vera juice, and avocado essential oil are added to the resulting mixture. The mixture is left to swell for 30 minutes. The remaining aqueous thyme extract is added, and the mixture is thoroughly mixed until smooth. The sheet mask is then soaked into a sheet mask. The soaked sheet mask is then hermetically sealed in individual packaging made of a combined barrier material (e.g., aluminum foil). Each package contains one mask. The resulting pectin-containing moisturizing sheet mask is easy to use and adheres well to the skin.

[0026] Example 1. Pre-mix 3g of low-esterified pectin with 3g of sunflower lecithin and 3g of fish collagen in a ratio of approximately 30ml, 10ml of aloe vera juice, and 1ml of avocado essential oil. Leave for 30 minutes to swell. Add the remaining aqueous thyme extract. Mix thoroughly until smooth. Then, soak a sheet mask. Next, seal the soaked sheet mask in an individual bag made of a combined barrier material (e.g., aluminum foil). Each bag contains one mask. The resulting pectin-containing sheet mask is easy to use and adheres well to the skin.

[0027] Figure 1 shows a pectin-containing moisturizing sheet mask: a - pectin-containing moisturizing sheet mask before application to facial skin; b - pectin-containing moisturizing sheet mask on facial skin. Analysis of the data in Figure 1 shows that the pectin-containing moisturizing sheet mask adheres well to the face, without any leakage.

[0028] The quality indicators of the pectin-containing solution for impregnating the fabric mask are presented in Table 1.

[0049] Using a pectin-containing moisturizing sheet mask (moistened, sealed) on clients with dry or combination skin types, dehydrated, and mild flaking, the masks were easy to use, adhered well to the face, and did not run. After use, the skin became smooth and soft, the feeling of tightness was completely eliminated, and visible flaking was reduced.

[0050] Pectin-containing moisturizing tissue mask is recommended for use.

[0051] Clinical case. Patient O, 40, presented with complaints of a dull, "tired" complexion, uneven skin texture with fine wrinkles, especially noticeable when smiling, and dry skin. The patient had previously undergone superficial peels with lactic and mandelic acids. After each procedure, the patient noted severe dryness, tightness, and skin reactivity for 5-7 days. He also experienced fine, lamellar peeling, with increased sensitivity to conventional skin care products.

[0052] Examination revealed normal skin, prone to dehydration and signs of early photoaging. Skin turgor is reduced, and the skin surface is matte and uneven. Fine, pityriasis-like scaling is noted in the perioral and malar areas. Diffuse erythema is visible and sensitive to touch. A positive effect of a course of peels was also noted: improved texture (smoothing of the surface relief) and lightening of solar lentigines in the malar area.

[0053] A change in post-peel care is recommended. An intensively moisturizing pectin-containing sheet mask with sunflower lecithin, collagen, thyme water extract, aloe juice, and avocado oil, provided by the Maykop State Technological University (developed by Professor Z.N. Khatko et al.), was prescribed for clinical testing (acceptance certificate dated November 13, 2025, implementation certificate dated December 15, 2025).

[0054] How to use: On the 2nd and 4th days after each chemical peel procedure (during the period of active peeling). Outside of treatment weeks, use once a week to maintain high hydration levels.

[0055] Apply in the evening after cleansing for 15-20 minutes. After removing, pat any remaining essence into the skin and apply a soothing cream on top.

[0056] After the 4th peeling procedure using the mask, the patient noted a reduction in the post-peel discomfort period from 5-7 days to 2-3 days. Peeling became less profuse and more manageable. After using the mask, the skin felt "nourished and firm," and the feeling of tightness disappeared. Upon examination on the 3rd day after the 4th procedure, minimal signs of dehydration were noted, and skin turgor was maintained. Peeling was absent. Erythema subsided. The skin was hydrated and had an even glow, indicating an effective recovery phase. The overall result of the peeling course (evened tone and texture) was achieved with greater patient comfort.

[0057] An intensively moisturizing pectin-containing tissue mask with sunflower lecithin, collagen, thyme water extract, aloe juice and avocado oil has proven its high effectiveness as a specialized product for post-procedural rehabilitation.

[0058] The mask has become an integral part of the treatment and prevention protocol, increasing patient compliance and improving the final aesthetic result. It is recommended for use after any barrier-damaging procedures (laser resurfacing, microdermabrasion) and as a first aid treatment for severe dehydration.
