Leuphasyl vs Silk Peptides
A side-by-side research comparison of Leuphasyl and Silk Peptides across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Leuphasyl | Silk Peptides |
|---|---|---|
| Full name | Leuphasyl (Pentapeptide-18) | Hydrolyzed Silk Fibroin Peptides |
| 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. | Form hydrogen-bonded films on skin for moisture retention. Absorbed peptides provide substrates for keratin/collagen synthesis. Exhibit antioxidant and tyrosinase-inhibiting activity. |
| Molecular weight | 599.7 Da | 500-2,000 Da |
| Half-life | 6-10 hours (topical) | 3-5 hours |
| Bioavailability | Moderate (topical) | Moderate (topical/oral) |
| Typical dose | 3-5% solution | 1-5% topical or 2-5g oral |
| Frequency | 2x daily | Daily |
| Route | Topical | Topical or Oral |
