Matrixyl Synthe'6

Also known as: Palmitoyl Tripeptide-38, Matrixyl Synthe6, Matrixyl Synthe'6 Peptide

All skin types

What It Is

A second-generation matrikine peptide from Sederma — Palmitoyl Tripeptide-38 — that works alongside Matrixyl 3000 by targeting a broader range of structural skin proteins than its predecessor.

What It Does

Matrixyl Synthe'6 stimulates synthesis of six structural skin components: Collagen I, III, and IV, Fibronectin, Laminin-5 (now laminin-332), and Hyaluronic Acid. By expanding beyond what Matrixyl 3000 targets alone, it provides more comprehensive extracellular matrix support and deeper anti-aging coverage.

Best For

Fine linesDeep wrinklesLoss of firmnessExtracellular matrix supportMulti-target anti-aging

Benefits

  • Stimulates 6 structural proteins vs. Matrixyl 3000's narrower collagen/elastin focus
  • Addresses deeper wrinkles alongside fine lines
  • Supports Laminin-5 and Fibronectin — key components of the dermo-epidermal junction
  • Zero irritation risk — appropriate for all skin types including sensitive
  • Synergistic with Matrixyl 3000 in combined formulas (Matrixyl 10%)

When to Be Careful

  • Same gradual timeline as Matrixyl 3000 — 8–12 weeks for visible results
  • Expensive as an isolated ingredient — most accessibly found in multi-peptide formulas

Why This Gets Hype

Matrixyl Synthe'6 represents a genuine evolution from Matrixyl 3000. Sederma data shows statistically significant reductions in wrinkle volume. When combined with Matrixyl 3000 in a 10% total concentration formula, you're getting the broadest possible peptide-driven collagen support currently available at an accessible price.

What People Often Misunderstand

People assume Matrixyl Synthe'6 replaces Matrixyl 3000. They are designed to be used together — their protein targets overlap partially but their combined effect is more comprehensive than either alone.

Best Routine Slot

AM or PM — no restrictions. Pairs naturally with SPF in the morning.

Good Match For

People focusing on anti-aging who want comprehensive structural support without retinol or acids.

Proceed Carefully If…

No known concerns.

Signs You May Be Overdoing It

FAQs About Matrixyl Synthe'6

What is Matrixyl Synthe'6?
A matrikine peptide (Palmitoyl Tripeptide-38) that stimulates 6 structural skin proteins including collagen types I, III, IV, fibronectin, laminin-5, and hyaluronic acid — broader coverage than Matrixyl 3000 alone.
What is the difference between Matrixyl 3000 and Matrixyl Synthe'6?
Matrixyl 3000 (Pal-Tripeptide-1 + Pal-Tetrapeptide-7) focuses on collagen and elastin. Matrixyl Synthe'6 (Pal-Tripeptide-38) adds fibronectin, laminin-5, and hyaluronic acid support. Combined, they address the full structural matrix.
Can I use Matrixyl Synthe'6 and Matrixyl 3000 together?
Yes — they are specifically designed to work together. The Ordinary Matrixyl 10% + HA contains both at a combined 10% concentration, which is one of the highest peptide concentrations available at this price point.
