Educational reference only

This page helps you understand what to track for Matrixyl. It is not medical advice, a prescription, or a recommendation to use this peptide. Discuss dose, route, timing, storage, and safety with a qualified healthcare professional.

Overview

Matrixyl is a palmitoylated pentapeptide derived from a procollagen-I fragment, designed to send a 'wound-healing' signal to fibroblasts and trigger collagen synthesis. The fatty-acid (palmitoyl) tail enables skin penetration. The Matrixyl 3000 variant pairs Pal-KTTKS with Pal-GHK for compounded matrikine signalling.

Also known as: Palmitoyl Pentapeptide-4, Pal-KTTKS, Matrixyl 3000 (with Pal-GHK).

Mechanism and timing snapshot

Mimics a fragment of procollagen-I that fibroblasts interpret as 'damage signal,' triggering collagen, elastin, and glycosaminoglycan synthesis. Palmitoyl tail enables penetration through the lipid-rich stratum corneum.

Safety notes

Common and rare side effects listed in the catalog

  • Extremely well-tolerated topically
  • Mild irritation (formulation-dependent)
  • Allergic reaction (rare)

Contraindications and warnings

No contraindications or warnings listed in the catalog.

Other considerations

  • Consistent multi-month use is required — collagen synthesis is slow.
  • Pairs well with retinoids and vitamin C in established skincare routines.
  • Marketed under many brand names; concentration and formulation matter more than brand.
