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. It works by promoting the cohesion of skin cells and reinforcing the skin’s structural matrix, 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.
