Matrixyl (Palmitoyl Pentapeptide)

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Matrixyl (Palmitoyl Pentapeptide) — a trademarked signal-peptide ingredient built around palmitoyl pentapeptide-4, designed to encourage the skin's collagen-supporting activity. It is one of the most recognized anti-aging peptides and is often paired with other peptides in firming formulas. The palmitoyl portion is a fatty acid added to help the peptide penetrate the skin.

Key points

  • Matrixyl is a brand name for peptide actives, most commonly palmitoyl pentapeptide-4 and related palmitoyl peptide blends.
  • It functions as a signal peptide, aiming to prompt skin to support collagen and matrix proteins.
  • The attached palmitoyl (fatty-acid) group improves the peptide's ability to pass into the skin.
  • It is studied for improving the appearance of fine lines and skin firmness with consistent use.
