Palmitoyl Tetrapeptide-1
What is Palmitoyl Tetrapeptide-1?
Palmitoyl Tetrapeptide-1 is a lab-synthesized signal peptide made from four amino acids—glycine, glutamine, proline, and arginine—chemically bound to palmitic acid to enhance skin penetration. It falls under cosmetic conditioning agents and appears in serums, creams, and eye treatments aimed at mature skin. Functionally, it mimics natural matrikines, fragments from the skin's extracellular matrix that communicate with fibroblasts. This prompts increased production of collagen types I, III, and IV, along with fibronectin, laminin-5, and hyaluronic acid, contributing to improved dermal structure and resilience. Valued for its targeted bioactivity, it integrates seamlessly into formulations at minimal levels without altering texture or stability.
