Palmitoyl Pentapeptide-3 (Matrixyl)
What is Palmitoyl Pentapeptide-3 (Matrixyl)?
Palmitoyl Pentapeptide-3 is a lipopeptide formed by attaching palmitic acid to a five-amino-acid chain (lysine-threonine-threonine-lysine-serine). This modification enhances skin penetration compared to free peptides. Primarily used in anti-aging serums, creams, and moisturizers, it acts as a skin conditioning agent. In formulations, it mimics natural matrikines—fragments of extracellular matrix proteins—that signal fibroblasts to produce collagen types I, III, and IV, along with glycosaminoglycans and fibronectin. This mechanism aims to reinforce the skin's supportive structure, promoting softness and flexibility without harsh exfoliation.
