Description

Technical Field

[0001] The invention belongs to the technical field of skin repair, and in particular relates to a natural skin repair composition. Background Art

[0002] Skin is the first protective layer of the human body, which can protect tissues and organs from external invasion and stimulation and maintain the health of the body. However, with the increase of age and external stimulation, a large number of skin problems will appear, including sagging, roughness, capillary dilation, etc. Therefore, how to repair skin diseases and maintain skin integrity has become the ultimate pursuit of restorative cosmetics.

[0003] Current restorative cosmetics pursue highly effective care effects, but their ingredients are generally unstable and have certain irritation, resulting in poor skin repair effects, inability to provide long-term stable repair, and inability to meet reagent application requirements. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides a natural skin repair composition that solves the defects of the existing skin repair compositions. It uses dimethyl isosorbide as a permeate to bring hydroxypropyl tetrahydropyrantriol into the dermis and epidermis, and cooperates with ectoine, sodium hyaluronate and squalane to form a three-dimensional hyaluronic acid repair and protection effect of internal promotion and external coating, thereby achieving excellent skin repair effects.

[0005] In order to achieve the above technical objectives, the technical solution of the present invention is:

[0006] A natural skin repair composition comprising:

[0007] Dimethyl isosorbide, hydroxypropyl tetrahydropyrantriol, ferulic acid, dandelion extract, chamomile extract, sodium hyaluronate, ectoine, squalane, fruit acid, water.

[0008] The mass proportion of dimethyl isosorbide in the skin repair composition is 3-5%. Dimethyl isosorbide has good permeability and can carry a large amount of active substances to penetrate the skin, thereby improving the internal transportation of active substances and achieving the effect of fully exerting the active components; dimethyl isosorbide has its own dissolving effect, which improves the solubility and dispersibility of active substances and ensures the penetration of active substances.

[0009] The mass proportion of hydroxypropyl tetrahydropyrantriol in the skin repair composition is 1-4%. Hydroxypropyl tetrahydropyrantriol itself is a xylose derivative, can be extracted naturally, has good safety, and has a good promoting effect in the skin, improves the synthesis of substances such as collagen, improves the saturation of the dermis and epidermis, and can also increase the water content between the extracellular matrix, thereby stimulating the synthesis of substances such as proteoglycans; under the penetration-promoting effect of dimethyl isosorbide, hydroxypropyl tetrahydropyrantriol can enter between the epidermis and the dermis, increase the permeability, and effectively stimulate the production of skin aminoglucan. Hyaluronic acid, one of the main components of skin aminoglucan, can directly act on the dermis, and can form an in-situ filling effect in the dermis to ensure the fullness of the skin. Further, the promotion of synthesis of hydroxypropyl tetrahydropyrantriol directly acts on the dermis, effectively improving the production of collagen and skin aminoglucan, not only has good safety and stability, but also ensures that the skin is full and elastic.

[0010] The mass proportion of ferulic acid in the skin repair composition is 0.5-0.9%. Ferulic acid is also called 3-methoxy-4-hydroxycinnamic acid, which is a derivative of cinnamic acid. Ferulic acid itself is a phenolic plant component with strong antioxidant activity, which can effectively increase the content of glutathione and nicotinamide adenine dinucleotide phosphate in irradiated cells, and has a protective effect on irradiated endothelial cells. At the same time, ferulic acid can effectively regulate the expression of heme oxygenase and can form a radiation protection effect between cells. Ferulic acid itself has the characteristics of good small molecule water solubility, not only has good skin permeability, but also improves the penetration effect with the cooperation of dimethyl isosorbide, thereby ensuring that ferulic acid exerts biological activity in the skin.

[0011] The mass proportion of Ecdoin in the skin repair composition is 10-15%. Ecdoin, also known as tetrahydromethylpyrimidine carboxylic acid, has protective, protective repair and regenerative effects on the skin. Ecdoin itself has good stability and protective properties, maintains the moisture balance of the skin, improves the dryness and roughness of the skin, and thus helps to repair the skin barrier. At the same time, Ecdoin can reduce transepidermal water loss and increase the degree of hydration, thereby achieving a moisturizing and protective effect. Ecdoin can improve skin microcirculation by promoting the synthesis of macromolecules such as extracellular hyaluronic acid and glycoproteins, thereby achieving the effect of improving the skin. Ferulic acid forms a protective layer on the skin surface with its stability and protectiveness, which has the effect of soothing the skin; ferulic acid takes penetration as the basis and directly acts on enzymes, glutathione and nicotinamide adenine dinucleotide phosphate in the skin to achieve inner layer protection. Therefore, ferulic acid and ectoine form a dual protective effect of the surface and inner layers, which has an excellent promoting effect on protection. In terms of skin repair, ferulic acid can effectively eliminate oxygen free radicals and play an antioxidant role. Combined with the blood circulation promoting effect of ferulic acid, it improves the skin's detoxification effect and repairs damaged skin cells; ectoine forms a synergistic promotion effect with hydroxypropyl tetrahydropyrantriol that penetrates into the skin, effectively enhancing the formation of hyaluronic acid, which not only ensures the water content between the extracellular matrix and forms a triggered repair effect, but also forms an integrated repair and filling effect from the dermis to the epidermis, improving the skin's fullness and elasticity.

[0012] The mass proportion of the dandelion extract in the skin repair composition is 0.1-0.3%. The dandelion extract has the effect of clearing away heat and detoxification, and can quickly eliminate toxin substances in the skin and reduce toxin accumulation. That is, the dandelion extract can deep clean the skin and improve the freshness and cleanliness of the skin. At the same time, dandelion can effectively regulate the water and oil balance of the skin, and use the vitamin A, microbial E and other ingredients in the dandelion extract to promote the production of collagen and repair damaged cells. At the same time, rich vitamin C and chlorophyll and other ingredients improve whitening efficiency and ensure the whiteness and elasticity of the skin. Dandelion extract has a good effect of softening keratin, effectively reduces the flexibility of the skin surface, and helps to improve the penetration of dimethyl isosorbide, thereby improving the skin's self-activity and active ingredient absorption in a way that improves the skin's own angle, thereby improving the efficiency of skin repair.

[0013] The mass proportion of the chamomile extract in the skin repair composition is 0.2-0.5%. The chamomile extract itself contains a large amount of active ingredients, which can repair blood red streaks, help improve skin sensitivity, improve skin adaptability, and reduce the irritation of active ingredients to damaged skin. At the same time, the chamomile extract can have moisturizing and emollient properties, and improve the stability of the skin surface. Chamomile extract also has bactericidal and anti-inflammatory effects. It improves skin cleanliness and inflammation by improving skin metabolism. It cooperates with the deep cleansing of dandelion extract to form a good skin cleansing inside and outside, reduce the impact of toxins, and improve the tenderness of the skin itself; both dandelion extract and chamomile extract have good anti-inflammatory and antibacterial effects, preventing bacterial invasion during deep cleaning to ensure the antibacterial and anti-inflammatory effects on the surface.

[0014] The mass proportion of sodium hyaluronate in the skin repair composition is 0.1-0.5%. Sodium hyaluronate is a kind of glucuronic acid, which belongs to natural polysaccharide substances, has no species specificity, and is distributed in the cytoplasm and intercellular matrix, and can form lubrication and nourishment between cells. Sodium hyaluronate belongs to the skin's own substance, which can form a good supplement to the internal hyaluronic acid, that is, sodium hyaluronate can promote the supply of skin nutrition and the metabolism of waste through the proliferation and differentiation of epidermal cells, and promote the regeneration of skin at the damaged part; sodium hyaluronate has the effect of dilating capillaries and promoting blood circulation in the dermis, improving metabolism, and improving the effect of lubrication and arrogance. Therefore, sodium hyaluronate can promote internal and external metabolism, ensure that the dermis, epidermis and surface membrane form saturation and elasticity from the inside to the outside, and improve the tenderness of the skin. That is, hydroxypropyl tetrahydropyrantriol and ectoin promote the synthesis of hyaluronic acid in the skin, and cooperate with the supplementary nature of the surface layer of sodium hyaluronate to form the richness of internal and external hyaluronic acid and the fullness of cells. Sodium hyaluronate has UV protection and repair effects, and forms a dual protective effect on the surface and inner layer with ferulic acid and ectoine, forming a synergistic effect, achieving multiple protective and repair effects. At the same time, the synergy of hyaluronic acid and ectoine can achieve a balance between the epidermis on the epidermis and the external hyaluronic acid, ensuring the tension and elasticity of the epidermis; sodium hyaluronate and ectoine are both gel materials, which can increase the viscosity of the natural skin repair composition, reduce its fluidity, and help to form a good application effect during use. The sodium ions in sodium hyaluronate can increase the vitality of skin cells, promote cell renewal and repair, accelerate wound healing, reduce inflammatory reactions, and improve skin luster and elasticity.

[0015] The mass proportion of squalane in the skin repair composition is 2-5%. Squalane is a rare animal fat with high chemical stability and excellent feel. It has good affinity to the skin, low polarity and medium spreadability. The squalane has the function of strengthening the repair of the epidermis, showing excellent affinity, and can be integrated with the sebum membrane to form a protective barrier on the skin surface and ensure the balance between the skin and sebum. At the same time, squalane can effectively penetrate into the skin, promote the proliferation of skin basal cells, promote the opening of skin pores, promote blood microcirculation, enhance cell metabolism, and help repair damaged cells. Squalane can effectively promote the good penetration of hydroxypropyl tetrahydropyrantriol, dandelion extract and chamomile extract by promoting the opening of pores, ensuring the absorption and efficacy of active substances in cells; at the same time, squalane and sodium hyaluronate have good compatibility in the surface membrane and can effectively form protective properties.

[0016] The weight proportion of the fruit acid in the skin repair composition is 0.2-0.5%. The fruit acid is extracted from fruits and is an effective ingredient in natural fruits. The fruit acid can effectively reduce the adhesion of the epidermal stratum corneum, promote the shedding of the stratum corneum, and improve the softness and permeability of the skin surface. At the same time, the fruit acid in the small molecule system can have good permeability, promote the expansion of the superficial capillaries of the dermis, and improve the blood circulation of the skin.

[0017] In the skin repair composition, the balance is water. Water can form good absorbency in Ectoin and hyaluronic acid, can gel the entire skin repair composition, and form a stable homogeneous dispersion after use. The low fluidity of the gel can form a surface film on the skin to achieve a surface protection effect. At the same time, various active ingredients form their own effects during contact with the skin, ensuring the premise of active substance penetration, promoting the synthesis of substances such as hyaluronic acid, ensuring the plumpness of the skin inside and outside, and playing a good and both internal and external repair and protection effect.

[0018] The preparation method of the natural skin repair composition comprises the following steps:

[0019] Step 1, adding sodium hyaluronate and ectoine to water and stirring at low temperature to form a homogeneous gel solution, wherein the temperature of the low temperature stirring is 5-10° C. and the stirring speed is 300-500 r / min;

[0020] Step 2, stir hydroxypropyl tetrahydropyrantriol and ferulic acid evenly, then slowly add isosorbide dimethyl ether, and stir thoroughly to obtain a premix; the slow addition speed is 1-3 g / min, and the stirring speed for even stirring is 500-700 r / min;

[0021] Step 3, adding fruit acid and squalane to the homogeneous gel liquid and stirring evenly, then adding dandelion extract and chamomile extract in turn and stirring evenly, finally adding the premix, stirring at low temperature to obtain a natural skin repair composition, the stirring speed for stirring evenly is 200-400r / min, the temperature of the low-temperature stirring is 5-10°C, and the stirring speed is 500-800r / min.

[0022] The preparation method utilizes isosorbide to wet hydroxypropyl tetrahydropyrantriol and ferulic acid and form a homogeneous surface liquid film, which is then added into a homogeneous gel liquid. The insolubility of isosorbide dimethyl ether is utilized to ensure that hydroxypropyl tetrahydropyrantriol and ferulic acid are blocked by isosorbide dimethyl ether when added into the gel liquid, thereby forming a homogeneous dispersion.

[0023] It can be seen from the above description that the present invention has the following advantages:

[0024] 1. The present invention solves the defects of existing skin repair compositions, uses dimethyl isosorbide as a permeate to bring hydroxypropyl tetrahydropyrantriol into the dermis and epidermis, and cooperates with ectoine, sodium hyaluronate and squalane to form a three-dimensional hyaluronic acid repair and protection effect of internal promotion and external coating, thereby achieving excellent skin repair effects.

[0025] 2. The present invention utilizes the permeability of dimethyl isosorbide, the stratum corneum softening effect of dandelion extract and fruit acid, and the pore dilating effect of squalane to promote the multi-layer permeation system of active substances, thereby effectively improving the permeation and absorption effect of active substances.

[0026] 3. The present invention utilizes the protective effect of the biologically active system brought about by the regulating and promoting effect of ferulic acid, utilizes the promoting and protective effect of ectoine, and the application and compatibility of the surface film of sodium hyaluronate and squalane, to form a good multi-dimensional protective effect, reduce the consumption of ferulic acid, and also improve the regulating effect of ferulic acid in the epidermis.
