Copper Peptides vs Silk Peptides
A side-by-side research comparison of Copper Peptides and Silk Peptides across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Copper Peptides | Silk Peptides |
|---|---|---|
| Full name | Copper Peptide Complex (AHK-Cu, GHK-Cu variants) | Hydrolyzed Silk Fibroin Peptides |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Copper peptides deliver bioavailable copper to tissues while the peptide provides signaling to stimulate collagen I/III synthesis, attract immune cells for remodeling, and promote glycosaminoglycan production. | 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 | 340-410 Da (varies) | 500-2,000 Da |
| Half-life | 2-4 hours | 3-5 hours |
| Bioavailability | High (topical penetration) | Moderate (topical/oral) |
| Typical dose | 1-3% topical solution | 1-5% topical or 2-5g oral |
| Frequency | 1-2x daily | Daily |
| Route | Topical | Topical or Oral |
