Palmitoyl Pentapeptide-4 (Original Matrixyl) for Collagen & Wrinkle Reduction — Skin & Hair

First-generation Matrixyl peptide that stimulates collagen production and reduces wrinkle depth.

Overview

Palmitoyl Pentapeptide-4, known commercially as the original Matrixyl, is a signal peptide that mimics the amino acid sequence found in collagen breakdown products. When skin recognizes this sequence, it triggers collagen synthesis to replace what appears to be damaged collagen. Clinical studies demonstrate significant wrinkle reduction and improved skin firmness with consistent use. This peptide penetrates well into skin due to its palmitoyl fatty acid attachment. It's one of the most well-researched cosmetic peptides with extensive clinical validation.
