Acetyl Dipeptide-13 DIPHENYLGLYCINE  is a synthetic peptide commonly used in cosmetic formulations for its anti-aging and skin-protective properties. It is composed of a dipeptide (two amino acids) modified with an acetyl group and a diphenylglycine moiety, which improves its stability and skin penetration.
This peptide works by stimulating the skin’s natural regenerative processes, promoting collagen and elastin production, and supporting the skin’s extracellular matrix. It also has anti-inflammatory and skin-soothing effects, helping to reduce visible signs of aging such as fine lines, wrinkles, and sagging. Additionally, it may protect skin against environmental stressors and oxidative damage.
 
Applications: Used in anti-aging and skin-repair cosmetic products such as serums, creams, lotions, and eye treatments. It helps reduce fine lines and wrinkles, improves skin elasticity and firmness, and protects the skin from environmental stressors.
