About Sh-Polypeptide-121

Sh-Polypeptide-121 is a single-chain recombinant human peptide obtained by fermenting Escherichia coli.[1] The number 121 at the end of the name is only an identification number distinguishing different peptides; it does not indicate the amount used in a formulation or rank efficacy. In cosmetics, it is used to form a thin film on the surface of the skin, hair, or nails after application and to leave the skin's surface feeling soft and smooth.[2]
