- The peptide category includes many compounds with different mechanisms. Signal peptides like Matrixyl stimulate collagen production. Neurotransmitter-affecting peptides like Snap-8 and Syn-Ake relax facial muscles to reduce expression lines. Carrier peptides deliver minerals to skin cells.
- GHK-Cu functions as both a signal peptide (triggering collagen synthesis) and a carrier peptide (delivering copper). This dual function may explain its superior performance compared to single-function peptides.
- Clinical comparison showing GHK-Cu outperforming Matrixyl 3000 by 31.6% for wrinkle volume reduction suggests copper peptides represent the most effective single peptide option for wrinkle treatment.
- However, multi-peptide combinations may offer broader benefits than any single peptide alone.
