Elastin Peptides vs Palmitoyl Tetrapeptide-7
A side-by-side research comparison of Elastin Peptides and Palmitoyl Tetrapeptide-7 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Elastin Peptides | Palmitoyl Tetrapeptide-7 |
|---|---|---|
| Full name | Hydrolyzed Elastin Peptides | Palmitoyl Tetrapeptide-7 (Pal-GQPR) |
| 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. | Inhibits IL-6 release from keratinocytes and reduces inflammation-mediated MMP activation, preserving existing collagen while complementing Pal-GHK collagen building. |
| Molecular weight | 1,000-3,000 Da | 693 Da |
| Half-life | 4-6 hours | 8-12 hours (topical) |
| Bioavailability | Moderate (topical/oral) | Good (topical) |
| Typical dose | 1-5% topical or 2-5g oral | 2-4% in formulation |
| Frequency | Daily | 1-2x daily |
| Route | Topical or Oral | Topical |
