Acetyl Tetrapeptide-40
What is Acetyl Tetrapeptide-40?
Acetyl Tetrapeptide-40 is a synthetically produced short-chain peptide made from four amino acids, featuring an acetyl group at one end for stability. It falls under skin conditioning agents in cosmetic formulations, typically appearing in leave-on products like creams, serums, and lotions aimed at maintaining skin comfort. This ingredient functions through biomimetic action, interacting with skin receptors similar to natural peptides to support homeostasis and reduce reactivity from environmental or formulation stressors. Official databases such as the EU CosIng classify it as a miscellaneous skin conditioning agent without usage limits or warnings. Assessments from safety panels highlight its mild nature, aligning with low concern ratings from hazard evaluations. Its inclusion helps enhance product gentleness, particularly in multi-active blends.
