Palmitoyl Tripeptide-37 is a synthetic lipo-peptide with sequence Pal-KFK (Palmitoyl-Lys-Phe-Lys) that leaves thrombospondin-like action. It is an analog of Lipospondin. It is an ester of palmitic acid and Tripeptide-37 (KFK peptide) with an active Thrombospondin domain sequence.
Thrombospondins are proteins that activate TGF (transforming growth factor), increasing ECM (extracellular matrix) component production and playing an essential role in angiogenesis, ECM recovery, and tissue remodeling. Palmitoyl Tripeptide-37 activates latent TGF-β, boosting collagen and elastin synthesis by fibroblasts.
Incorporated in skin care applications, Palmitoyl Tripeptide-37 improves skin elasticity, firmness, and resilience, revealing a smoother, lifted, and youthful appearance. It is a safe, "smart," and effective ingredient for high-end anti-aging products.
