Caprooyl Tetrapeptide-3 is a synthetic signal peptide composed of four amino acids attached to a caprooyl (hexanoyl) group that enhances its stability and skin penetration. It is widely used in cosmetic formulations for its skin-repairing, anti-aging, and dermal restructuring properties.
This peptide helps stimulate the production of important components of the extracellular matrix (ECM) such as collagen, laminin, and fibronectin, which support the skin’s structural integrity. By strengthening the dermal-epidermal junction and promoting skin regeneration, Caprooyl Tetrapeptide-3 helps improve skin firmness, elasticity, and smoothness while reducing the visible signs of aging.
