Palmitoyl Pentapeptide-4
What is Palmitoyl Pentapeptide-4?
Palmitoyl Pentapeptide-4 is a lab-synthesized lipopeptide featuring palmitic acid linked to the pentapeptide sequence lysine-threonine-threonine-lysine-serine, known as KTTKS. Primarily featured in anti-aging skincare like serums, creams, and lotions, it serves as a skin conditioning agent. Its lipid moiety enhances skin penetration, allowing it to reach the dermis where it functions similarly to natural matrikines—fragments from collagen breakdown. This signals fibroblasts to boost synthesis of collagen I, III, IV, laminin-5, fibronectin, and glycosaminoglycans, aiding skin structure maintenance. By supporting the extracellular matrix, it contributes to skin suppleness and resilience. Commonly incorporated at trace levels, it blends seamlessly into emulsions and gels without impacting product stability or sensory qualities.
