Matrixyl
Palmitoyl Pentapeptide-4 (Pal-KTTKS)
Matrixyl is a trademarked cosmetic peptide developed by Sederma, consisting of the pentapeptide sequence KTTKS (Lysine-Threonine-Threonine-Lysine-Serine) linked to a palmitoyl fatty acid chain. The peptide is derived from the pro-collagen I C-terminal propeptide and functions as a matrikine—a messenger peptide that signals fibroblasts to increase production of collagen, elastin, and other extracellular matrix components. Research has demonstrated that Matrixyl can stimulate collagen synthesis by up to 350% and fibronectin production by up to 200% in cell culture studies. The palmitoyl modification enhances skin penetration and cellular uptake, making it one of the most effective topical anti-aging peptides available. Clinical studies have shown visible reduction in wrinkle depth and improved skin texture with regular use.
