Used in skincare formulations for its anti-aging properties, Acetyl Tetrapeptide-11 helps reduce the appearance of fine lines and wrinkles by supporting skin elasticity and stimulating collagen production. It works by promoting the cohesion of skin cells and reinforcing the skin’s structural matrix, including collagen types I, III, IV, and laminin V, leading to a smoother, firmer complexion. Commonly found in facial serums, creams, and eye treatments, it is valued for enhancing skin tone and texture with continued use.
