Argireline vs SNAP-25 Fragment
A side-by-side research comparison of Argireline and SNAP-25 Fragment across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Argireline | SNAP-25 Fragment |
|---|---|---|
| Full name | Argireline (Acetyl Hexapeptide-3) | SNAP-25 Inhibitory Fragment Peptide |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Competes with SNAP-25 for position in SNARE complex, partially inhibiting vesicle docking and neurotransmitter release, reducing muscle contraction intensity. | 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 | 889 Da | ~650 Da |
| Half-life | 8-12 hours (topical) | N/A (topical depot) |
| Bioavailability | Moderate (topical) | Topical penetration ~6-9% |
| Typical dose | 5-10% solution | 3-8% in formulation |
| Frequency | 2x daily | 2x daily |
| Route | Topical | Topical serum |
