- GHK-Cu (Copper Peptide)
- Activates TGF-β signaling, upregulates Type I and III collagen gene expression
- Mild reduction in surface redness, improved wound healing response
- 8–12 weeks for measurable dermal thickness increase
- Most research-supported anti-aging peptide; effects are cumulative and require consistent long-term application
- Matrixyl 3000 (Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7)
- Stimulates collagen synthesis, inhibits IL-6 inflammatory pathway
- Slight improvement in skin barrier function, reduced TEWL
- 6–10 weeks for visible wrinkle depth reduction
- Clinical trials show 15–20% wrinkle reduction after 8 weeks; two-week effects are minimal
- Argireline (Acetyl Hexapeptide-8)
- SNARE complex inhibitor, reduces muscle contraction depth
- Temporary softening of expression lines in application area
- 4–6 weeks for consistent muscle relaxation effect
- Works faster than collagen peptides but still requires 4+ weeks for noticeable results; often called 'topical Botox' but mechanism is different
- Palmitoyl Tripeptide-38 (Matrixyl Synthe'6)
- Stimulates six major components of dermal matrix and dermal-epidermal junction
- Improved surface texture, mild plumping
- 8–12 weeks for significant firmness improvement
- Newer peptide with promising in vitro data; clinical evidence less robust than GHK-Cu or Matrixyl 3000
