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

[0001] 【Technical field】 [0002] The invention belongs to the technical field of cosmetics, and in particular relates to a skin care product containing Chinese golden silk extract. [0003] 【Background technique】 [0004] Heart of beauty in everyone. Anti-aging skin care products have always been given considerable attention. According to the free radical theory of human aging, excess free radicals can cause damage to the body, oxidize unsaturated fatty acids into superoxide, and form lipofuscin. Excessive oxygen free radicals can also damage cell membranes and other important components, denature proteins and enzymes. This will cause the human skin to show inelasticity, dullness, age spots, dry skin, desquamation, and wrinkles. [0005] 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, the so-called lichen constituents that are quite different from those of many other ...
