Acetyl tetrapeptide-15（Cat No.:I021278）is a synthetic peptide designed to reduce skin sensitivity and discomfort by modulating the skin’s response to external irritants. It works by interacting with the skin’s neurosensory receptors, particularly reducing the activity of the pain-related TRPV1 receptor, thereby calming inflammation and improving skin tolerance. Commonly used in cosmetic and dermatological formulations, this peptide helps soothe sensitive skin, reduce redness, and enhance overall skin comfort. Its gentle, non-irritating profile makes it ideal for products targeting reactive or intolerance-prone skin, including moisturizers, serums, and post-treatment skincare solutions.
