Is Oligopeptide-27 natural?

Dominant route is chemical peptide synthesis from fermentation- or hydrolysate-derived amino acids. Recombinant or enzymatic production, where used, also yields only amino-acid mass, so the value is unchanged.

A 40-amino-acid peptide added to skin-care products as a skin-conditioning ingredient. It is assembled in a laboratory by joining amino acids, the building blocks of proteins, which are produced by fermentation or from hydrolysed plant and animal protein.

CosIng definition: Oligopeptide-27 is a synthetic peptide containing 40 amino acids consisting of alanine, arginine, asparagine, aspartic acid, glutamic acid, glutamine, glycine, isoleucine, lysine, methionine, proline, serine, threonine, tyrosine, and valine; Alanine, synthetic 40-unit peptide with arginine, asparagine, aspartic acid, glutamic acid, glutamine, glycine, isoleucine, lysine, methionine, proline, serine, threonine, tyrosine, and valine
