Acetyl Tetrapeptide-2  is a synthetic peptide composed of four amino acids with an acetyl group, designed for skin repair, anti-aging, and rejuvenation. It is widely used in cosmetic formulations to improve the structural integrity and appearance of the skin.
This peptide works by stimulating the skin’s extracellular matrix, promoting collagen and elastin production, and enhancing the skin’s natural repair mechanisms. It helps improve skin firmness, elasticity, and resilience, while reducing the appearance of fine lines, wrinkles, and sagging.
 
Applications: Used in anti-aging, skin-repair, and firming cosmetic products such as serums, creams, lotions, and eye treatments. Helps reduce fine lines and wrinkles, improve skin elasticity and firmness, and support overall skin regeneration and hydration.
