What Is Acetyl Tetrapeptide-11?
A synthetic peptide created by the acetylation (a chemical reaction that joins a stronger substance with a weaker one) of tetrapeptide-11, which is made up of amino acids leucine, proline and tyrosine. Acetyl tetrapeptide-11 helps skin become healthier by interacting with a signaling protein in skin’s surface that addresses how it looks and feels.
