Polypeptide is a compound composed of α -amino acids linked by peptide bonds. It is also the intermediate product of protein hydrolysis. Generally, a compound formed by dehydration and condensation of three or more amino acid molecules can be called polypeptide. Generally speaking, peptides are composed of more than 10 amino acids and have the nutritional structure of protein. In recent years, scientists have found in experiments that protein is not completely absorbed in the form of amino acids after hydrolysis, but is often absorbed in the form of peptides. The moisturizing factor of polypeptide stock solution can add antioxidant components to fight free radicals and effectively resist aging. Nowadays, many peptide skin care products on the market have strong anti-aging and anti-wrinkle effects. For example, we are familiar with tripeptide-1, conotoxin, octapeptide, hexapeptide, etc., and the wrinkle removal effect is very good. However, you should choose the polypeptide components that suit you according to your skin type. For example, if the skin itself is sensitive, octapeptide or hexapeptide is not recommended. It is recommended to use skin care products containing conotoxin, such as Nereis polypeptide peony water. Compared with other polypeptide components, spiropeptide is milder, can achieve the effect of wrinkle removal in time, has no irritation to the skin, and has a really good wrinkle removal effect.
