Palmitoyl Tetrapeptide-7
What is Palmitoyl Tetrapeptide-7?
Palmitoyl Tetrapeptide-7 is a lab-created lipopeptide formed by linking a short chain of four amino acids—glycine, glutamine, proline, and arginine—to palmitic acid, a fatty acid that enhances skin penetration. Primarily featured in anti-aging and calming skincare formulations like serums and creams, it acts as a signaling molecule. In products, it interacts with skin cells, particularly fibroblasts and keratinocytes, to modulate inflammatory responses by influencing cytokines like interleukin-6. This mechanism helps maintain skin barrier integrity and promotes a balanced cellular environment, contributing to overall skin conditioning without harsh actives. Its lipidated structure allows delivery into deeper skin layers, distinguishing it from water-soluble peptides.
