Matrixyl 3000
Palmitoyl Tripeptide-1 · Palmitoyl Tetrapeptide-7Active
Trade-named blend of two signaling peptides. Promoted for fine lines and firmness.
What it does
Matrixyl 3000 is the marketing name for a paired blend of palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7 — two signaling peptides developed by Sederma. The combination is marketed for fine lines and skin firmness, with manufacturer studies supporting modest effects over 8–12 weeks. Independent dermatologic evidence is weaker than the marketing suggests, but the side-effect profile is benign and the overall picture is 'mild positive contributor to a routine.'
