Palmitoyl Tripeptide-1
A collagen-boosting cosmetic peptide that mimics the body's wound-healing signal to stimulate collagen and elastin production in the skin.
What is Palmitoyl Tripeptide-1?
Palmitoyl Tripeptide-1 is a lipopeptide consisting of palmitic acid linked to the tripeptide GHK (glycine-histidine-lysine). It is a synthetic fragment of collagen that functions as a matrikine — a messenger that signals fibroblasts to produce new collagen, elastin, and glycosaminoglycans. It is a key ingredient in Matrixyl 3000 (where it is combined with Palmitoyl Tetrapeptide-7) and is one of the most widely used anti-aging peptides in professional skincare.

EmergingHow It Works
Palmitoyl Tripeptide-1 mimics a collagen fragment that your body produces when skin is damaged. When fibroblasts detect this signal, they ramp up production of new collagen, elastin, and hyaluronic acid — essentially tricking your skin into repairing itself from within.
