Acetyl Tetrapeptide-15 is a synthetic bioactive peptide used in cosmetic and dermatological formulations, mainly for soothing sensitive skin and reducing irritation. It is a short chain peptide made of four amino acids with an acetyl group attached to improve stability and skin penetration.
This peptide works by reducing the skin’s sensitivity to external stimuli by modulating neurotransmitter pathways that trigger irritation or discomfort. Because of this action, it is commonly used in anti-redness and calming skincare products.
