Acetyl Tetrapeptide-11 is a synthetic cosmetic peptide used primarily as a skin-conditioning and anti-aging active. It is designed to support epidermal structure and skin firmness by influencing proteins involved in cell adhesion and epidermal cohesion. 1. Basic introduction Structurally, it consists of four amino-acid residues—proline, proline, tyrosine, and leucine—with an acetyl group attached at the N-terminus. Regulatory databases identify it as 1-acetyl-L-prolyl-L-prolyl-L-tyrosyl-L-leucine. 2. Origin Acetyl Tetrapeptide-11 is synthetically produced rather than extracted directly from plants or animals. COSMILE Europe classifies its origin as synthetic, while Korean and Japanese cosmetic ingredient databases describe it as the reaction product obtained by acetylating…
