Palmitoyl Pentapeptide-4  is a synthetic peptide composed of five amino acids linked to a palmitoyl (fatty acid) group, which enhances skin penetration, stability, and lipophilicity. It is widely used in cosmetic and anti-aging formulations for its ability to stimulate collagen and extracellular matrix production, thereby improving skin firmness, elasticity, and overall texture.
This peptide also helps reduce fine lines, wrinkles, and signs of skin sagging, making it ideal for facial, eye, and neck treatments. The palmitoyl modification allows it to penetrate deeper into the skin, increasing the effectiveness compared to unmodified pentapeptides.
