Acetyl Tetrapeptide-11 is a synthetic peptide composed of four amino acids (tetrapeptide) with an acetyl group attached, enhancing its stability, bioavailability, and skin penetration. It is commonly used in cosmetic formulations for skin remodeling and anti-aging applications.
This peptide works by stimulating extracellular matrix (ECM) components, such as collagen and glycosaminoglycans, which are crucial for skin structure, firmness, and elasticity. It also promotes skin regeneration and repair, helping to reduce the appearance of wrinkles and sagging, particularly in areas like the face, neck, and décolleté.
