Elastin Peptides vs Leuphasyl
A side-by-side research comparison of Elastin Peptides and Leuphasyl across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Elastin Peptides | Leuphasyl |
|---|---|---|
| Full name | Hydrolyzed Elastin Peptides | Leuphasyl (Pentapeptide-18) |
| 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. | Binds enkephalin receptors on neuronal membranes, reducing calcium influx and neurotransmitter release at the presynaptic level. Works upstream of argireline. |
| Molecular weight | 1,000-3,000 Da | 599.7 Da |
| Half-life | 4-6 hours | 6-10 hours (topical) |
| Bioavailability | Moderate (topical/oral) | Moderate (topical) |
| Typical dose | 1-5% topical or 2-5g oral | 3-5% solution |
| Frequency | Daily | 2x daily |
| Route | Topical or Oral | Topical |
