Acetyl Tetrapeptide-5
What is Acetyl Tetrapeptide-5?
Acetyl Tetrapeptide-5 is a synthetic peptide made from four amino acids, with an acetyl group for stability. Developed in laboratories, it serves as a skin conditioning agent in cosmetic formulations, especially eye creams, serums, and moisturizers. It works by drawing moisture to the upper skin layers, enhancing hydration through humectant action, while also interacting with cellular processes to help balance fluid levels and maintain skin barrier function. Commonly featured in products for facial care, it promotes a plumper feel without adding oiliness. Its peptide structure allows it to penetrate superficially, aiding in sustained water binding in the stratum corneum for everyday use.
