Abstract

The invention relates to a skin care product containing a lethariella sinensis extract. The skin care product is prepared from an extract of lichen lethariella sinensis which serves as an active ingredient through selecting a substrate depending on a dosage form of the skin care product and compounding. The lichen extract has an excellent anti-oxidation effect, and is capable of effectively delaying skin aging, enhancing skin activity, reducing wrinkles, improving sebum composition, and increasing soft and moist degrees of skin; meanwhile, the skin care product, which is free from chemical ingredient, is safe, non-toxic, low in skin irritation and stable in nature, and the skin care product can improve skin metabolism when applied on the skin.

Description

【Technical field】 [0001] The invention belongs to the technical field of cosmetics, and particularly relates to a skin care product containing Chinese golden silk extract. 【Background technique】 [0002] Heart of beauty in everyone. In terms of anti-aging skin care products, people have always given considerable attention. According to the theory of human aging free radicals, excess free radicals can cause damage to the body, oxidizing unsaturated fatty acids into superoxide, and forming lipofuscin. Excessive oxygen free radicals can also damage cell membranes and other important components, and denature proteins and enzymes. This will make human skin appear inelastic, dull, age spots and dry skin, scaling, wrinkles and so on. [0003] Lichens are symbionts composed of certain fungi and algae, and are a group of plants that occupy a special position in botany. The metabolites of lichens, so-called lichen components, are completely different from the components of many ot...
