Comparison table
| Attribute | Leuphasyl | Matrixyl |
|---|---|---|
| Full name | Leuphasyl (Pentapeptide-18) | Matrixyl (Palmitoyl Pentapeptide-4 / Pal-KTTKS) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Binds enkephalin receptors on neuronal membranes, reducing calcium influx and neurotransmitter release at the presynaptic level. Works upstream of argireline. | Signals through TGF-B pathway to stimulate fibroblast production of collagen I, III, IV, fibronectin, and hyaluronic acid. Palmitoyl chain enhances penetration. |
| Molecular weight | 599.7 Da | 802.1 Da |
| Half-life | 6-10 hours (topical) | 6-12 hours (topical depot) |
| Bioavailability | Moderate (topical) | Moderate (topical) |
| Typical dose | 3-5% solution | 2-8% in serum/cream |
| Frequency | 2x daily | 1-2x daily |
| Route | Topical | Topical |
