What Is Palmitoyl Tripeptide-1?
Palmitoyl Tripeptide-1 is a synthetic peptide that mimics the body's natural mechanism for stimulating collagen production. It acts as a signal peptide, communicating with fibroblasts to increase synthesis of collagen, elastin, and glycosaminoglycans.
Often combined with Palmitoyl Tetrapeptide-7 in the trademarked complex Matrixyl 3000, this peptide has demonstrated significant anti-wrinkle effects in clinical studies. The palmitoyl group enhances skin penetration.
