アセチルテトラペプチド-11

Synonyms: Acetyl Tetrapeptide-11, N-Acetyl-L-prolyl-L-prolyl-L-tyrosyl-L-leucine, Ac-Pro-Pro-Tyr-Leu-OH

Acetyl Tetrapeptide-11 is a synthetic peptide composed of four amino acids—proline, proline, tyrosine, and leucine—with an acetyl group attached to the N-terminus. This specific sequence is designed to mimic a fragment of the natural protein matrikine, which plays a role in skin matrix remodeling. The acetylation enhances its stability and bioavailability, making it a valuable ingredient in advanced cosmetic formulations.

In the realm of cosmetic chemistry, Acetyl Tetrapeptide-11 is recognized for its ability to support the skin’s extracellular matrix, particularly by promoting the synthesis of collagen and other structural proteins. It is often incorporated into anti-aging products, serums, and creams aimed at reducing the appearance of fine lines and improving skin firmness. Its mechanism involves signaling fibroblasts to produce more collagen, thereby reinforcing the skin’s supportive structure.
