Matrixyl: Research Profile, Dosages & Supplier Prices
Matrixyl is a cosmetic / tissue research compound with a molecular weight of 802.1 g/mol and a research half-life of topical/local research use; palmitoyl tail improves skin retention. Matrixyl (palmitoyl pentapeptide-4) is a lipopeptide built from the KTTKS sequence - a matrikine fragment of collagen type I - conjugated to a palmitic acid tail that improves skin penetration and retention. Matrikines are natural collagen breakdown fragments that signal fibroblasts to begin repair; Matrixyl packages that signal in a delivery-optimized form.

What is Matrixyl?
It is among the most clinically studied cosmetic peptides: double-blind trials report increased collagen and fibronectin synthesis and measurable wrinkle reduction with topical use. In research it serves as the reference matrikine peptide for studying fibroblast activation, extracellular matrix synthesis, and lipid-conjugation delivery strategies. The popular 'Matrixyl 3000' formulation pairs it with palmitoyl tetrapeptide-7.
Mechanism of Action (Research Context)
Matrikine signaling: the KTTKS motif (from collagen I alpha chains) activates fibroblasts, upregulating collagen I/III, fibronectin and elastin synthesis. The palmitoyl tail enhances stratum corneum penetration and peptide stability.
