Matrixyl vs SNAP-25 Fragment
A side-by-side research comparison of Matrixyl and SNAP-25 Fragment across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Matrixyl | SNAP-25 Fragment |
|---|---|---|
| Full name | Matrixyl (Palmitoyl Pentapeptide-4 / Pal-KTTKS) | SNAP-25 Inhibitory Fragment Peptide |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Signals through TGF-B pathway to stimulate fibroblast production of collagen I, III, IV, fibronectin, and hyaluronic acid. Palmitoyl chain enhances penetration. | Directly competes with the SNAP-25 binding domain in SNARE complex formation, providing highly specific inhibition of vesicle fusion at facial neuromuscular junctions. |
| Molecular weight | 802.1 Da | ~650 Da |
| Half-life | 6-12 hours (topical depot) | N/A (topical depot) |
| Bioavailability | Moderate (topical) | Topical penetration ~6-9% |
| Typical dose | 2-8% in serum/cream | 3-8% in formulation |
| Frequency | 1-2x daily | 2x daily |
| Route | Topical | Topical serum |
