Cosmetic & Copper Peptides

Cosmetic and copper peptides are short, often lipid-modified sequences that are widely used in cosmetic science and studied in skin cell research. This range includes the copper complex GHK-Cu, palmitoylated peptides such as PAL-GHK and Matrixyl (palmitoyl pentapeptide-4), and the SNAP-25 mimetic Snap-8.
In the laboratory they are used in fibroblast and keratinocyte assays of collagen and matrix production, and in skin-penetration models. Here they are sold as research reagents only, not as cosmetic products or ingredients for formulation.
