Matrixyl (Palmitoyl Pentapeptide-4)
Cosmetic / ResearchPalmitoylated matrikine / collagen signaling peptide
Matrixyl (Palmitoyl Pentapeptide-4) is a lipopeptide that has been studied in dermatology research for its effects on collagen I, III, and IV synthesis, fibronectin, and hyaluronic acid production. Published research has investigated its role in extracellular matrix remodeling and skin structure maintenance. RaysunPeptide supplies Matrixyl for qualified research and laboratory applications.
Mechanism of Action
The KTTKS peptide fragment is associated with extracellular-matrix signaling, while palmitoylation improves lipid affinity and supports incorporation into topical formulations.
