Palmitoyl Tripeptide-38
What is Palmitoyl Tripeptide-38?
Palmitoyl Tripeptide-38 is a lab-made lipopeptide, featuring a palmitic acid chain attached to a specific tripeptide sequence. Developed for cosmetic use, it belongs to the category of signal peptides in anti-aging formulations. In products like serums and creams, it functions by acting as a matrikine mimic—small signaling molecules naturally produced during skin repair processes. This peptide interacts with fibroblasts, the cells responsible for extracellular matrix production, encouraging synthesis of key structural proteins such as collagens I, III, and IV, along with fibronectin and laminin-5. Typically incorporated at low concentrations, it aims to bolster the skin's supportive framework over time with consistent application.
