Elastin Peptides vs Matrixyl
A side-by-side research comparison of Elastin Peptides and Matrixyl across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Elastin Peptides | Matrixyl |
|---|---|---|
| Full name | Hydrolyzed Elastin Peptides | Matrixyl (Palmitoyl Pentapeptide-4 / Pal-KTTKS) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Elastin-derived peptides bind the elastin receptor complex (S-Gal) on fibroblasts, triggering tropoelastin production and elastic fiber assembly. | Signals through TGF-B pathway to stimulate fibroblast production of collagen I, III, IV, fibronectin, and hyaluronic acid. Palmitoyl chain enhances penetration. |
| Molecular weight | 1,000-3,000 Da | 802.1 Da |
| Half-life | 4-6 hours | 6-12 hours (topical depot) |
| Bioavailability | Moderate (topical/oral) | Moderate (topical) |
| Typical dose | 1-5% topical or 2-5g oral | 2-8% in serum/cream |
| Frequency | Daily | 1-2x daily |
| Route | Topical or Oral | Topical |
