Palmitoyl Tetrapeptide-20 is a synthetic peptide consisting of four amino acids (tetrapeptide) linked to a palmitoyl (fatty acid) group, which enhances lipophilicity, stability, and skin penetration. The palmitoyl group allows this peptide to effectively penetrate the skin barrier, making it highly suitable for topical cosmetic formulations.
This peptide is primarily used for skin brightening, anti-aging, and antioxidant applications. Palmitoyl Tetrapeptide-20 helps inhibit the overproduction of melanin, promoting a more even skin tone and reducing hyperpigmentation. It also supports collagen synthesis and skin repair, which can improve skin texture, firmness, and overall radiance.
