Bletilla striata is an ancient traditional Chinese medicine for astringent hemostasis, beauty and beauty, known as "whitening fairy". Bletilla striata, which is rich in Bletilla striata gum, can directly participate in the repair and metabolism of damaged tissues or cells, and can significantly promote the formation of keratinocytes. Rubbed externally, it can beautify the spots and make the skin smooth and without traces. Adding Bletilla striata gum to anti-aging and nourishing skin cosmetics can supplement skin nutrition, eliminate excess free radicals in the body, and delay skin aging. "Medicinal Properties" says that it "treats sores on the face and makes the muscles slippery". "Compendium of Materia Medica" Yunqi "wash the face black, remove freckles". Bletilla striata also has the functions of moisturizing and anti-wrinkling, improving skin nutrition, treating chapped hands and feet, and delaying skin aging. Therefore, Bletilla striata is an ideal natural botanical additive for cosmetics, which can moisturize the skin and make it smooth as jade.

Cordyceps flower contains a variety of rich nutrients, which can nourish blood, nourish skin, moisturize skin and skin care, and have a good cosmetic effect. The polysaccharides in Cordyceps flowers can eliminate free radicals, improve the activity of antioxidant enzymes and inhibit the activity of lipid peroxidation, and play a role in protecting biofilms and delaying aging; the proteins and amino acids contained in them can promote cell metabolism and have Conducive to cell regeneration. Cordyceps can also improve the cold tolerance of the human body, reduce fatigue, and delay skin aging.

Lavender is known as the "King of Herbs", which is beneficial to wound healing, and has the functions of removing scars, controlling oil, regenerating, anti-inflammatory, and repairing damaged skin. Lavender is suitable for any skin, can promote cell regeneration, keep skin elastic and delay skin aging.

In addition, it also has the functions of auxiliary solubilization, emulsification and stabilization, and can also increase the solubility of the drug and the stability of the system while forming a film.

Hydroxypropyl methylcellulose has certain film-forming properties, stability and thickening properties. When used as an additive, it can effectively improve the fluidity of the system, enhance adhesion and bond strength, improve the film-forming effect of other materials, and improve skin feel. In addition, it can also be used as a dispersant to improve the dispersibility of the drug, which is beneficial to the exertion of the drug effect and has no irritation to the skin and mucous membranes.

Glycerin absorbs quickly, and is a good hydrating product for peeling skin in seasons, skin with acne scars, and sensitive skin. The high-purity glycerin is mixed with water and used, and the moisturizing effect is very good. After use, the skin is moist, soft and comfortable to touch. Glycerin is a dynamic moisturizing agent that forms a thin film on the skin, which can isolate the air and prevent the evaporation of water, and can also absorb the moisture in the air. The mild nature of glycerin provides gentle hydration, leaving skin soft and supple. Good safety to the skin, not easy to cause allergies.

The polyvinyl alcohol and methyl cellulose of the present invention have good film-forming properties; sodium alginate and sodium carboxymethyl cellulose can increase the stability of the system; niacinamide, milk and glycerin play a moisturizing effect together; Trehalose, honey and Cordyceps flower complement each other to delay skin aging; Cordyceps flower, Lavender, and milk have antioxidant and anti-inflammatory effects; Honey, milk, and niacinamide complement each other to make skin white and delicate.

The present invention adopts natural medicine extract as raw material, adds safe and non-irritating film-forming agent and thickening agent to complement each other, and has the functions of delaying aging, anti-oxidation, repairing damaged cells and the like. The prepared hand mask can not only whiten and moisturise, but also can exfoliate and lighten fine lines, anti-oxidation, anti-inflammatory and anti-aging. Compared with the prior art, the present invention has the characteristics of quick onset, less side effects, uniform and delicate products, fragrant smell, and effective ingredients can penetrate deeply into the skin of the hands, so as to achieve the effects of nourishing, whitening and repairing, so that the skin of the hands is tender and white. Ruddy and shiny.
