sh-Polypeptide-7 is a synthetic part of human growth hormone (hGH) also called Somatotropin. It repeats 20 amino acid sequences from 191 of hGH and mimics its action, stimulating the growth, reproduction, and regeneration of skin cells.
sh-Polypeptide-7 synthesized with recombinant technology where into the genes of bacteria e.g. E. coli incorporated a part of human DNA. E. Coli produces the polypeptide like its proteins. Resulting peptides get the prefix "rh-" recombinant human or "sh-" in the designation of cosmetic ingredients, which means synthetic human.
In skin care applications, sh-polypeptide-7 helps to reduce the appearance of fine lines and wrinkles, promoting cell vitality and exposing a youthful, healthy, and refreshed appearance. In hair care preparations, it promotes hair growth and development, strengthening and stimulating follicles.
