Matrixyl 3000
Palmitoyl tripeptide-1 + tetrapeptide-7, palmitoyl pentapeptide-4, Argireline, Matrixyl · Cosmetic peptide (topical)
What it is
The flagship anti-wrinkle peptide complex in commercial skincare — Matrixyl 3000 is palmitoyl tripeptide-1 plus palmitoyl tetrapeptide-7 (the original Matrixyl is palmitoyl pentapeptide-4), designed to signal collagen production through the skin. Often formulated alongside Argireline, a separate cosmetic peptide.
What human evidence shows
Manufacturer-funded studies and small published trials show measurable wrinkle-depth improvements over 8-12 weeks — better evidence than most cosmetic ingredients, weaker than any drug standard. The palmitoyl tail is legitimate penetration chemistry.
Risks
Topical and low-stakes: occasional irritation or sensitivity, and premium pricing on modest effects. Products made outside cosmetic manufacturing standards carry contamination and concentration uncertainty that finished retail products do not.
Legal status
US: cosmetic ingredient — not subject to FDA drug preapproval, but cosmetics and their manufacturers remain regulated under federal cosmetics law.
