Acetyl tetrapeptide-3 is widely used in the cosmetic and skincare industry for its anti-aging properties. It is incorporated into formulations such as serums, creams, and lotions to help reduce the appearance of fine lines and wrinkles by promoting skin elasticity and firmness. The peptide works by stimulating the production of collagen and elastin, essential proteins that maintain the skin's structure and resilience. Additionally, it aids in improving skin hydration and texture, giving a more youthful and radiant appearance. Its ability to support skin repair and regeneration makes it a popular ingredient in products targeting mature or damaged skin.
