- Signal Peptides (Matrixyl)
- Upregulate COL1A1/COL3A1 gene transcription via integrin receptor binding
- 8–12 weeks
- 117% increase in procollagen I synthesis (biopsy-confirmed)
- Addresses collagen loss. The structural deficit underlying wrinkle formation
- Neuromuscular Blockers (Argireline)
- Compete with SNAP-25 to reduce acetylcholine release at neuromuscular junction
- 2–4 weeks
- 27% reduction in dynamic wrinkle depth (profilometry)
- Prevents mechanical stress that re-damages newly synthesised collagen
- Copper Peptides (GHK-Cu)
- Deliver copper to activate lysyl oxidase (collagen cross-linking) and SOD (antioxidant defence)
- 6–10 weeks
- 18% increase in dermal density; 56% reduction in MMP-1 activity
- Ensures deposited collagen is correctly cross-linked and protected from enzymatic degradation
- Antioxidant Peptides (Carnosine)
- Scavenge reactive carbonyl species to prevent collagen glycation
- 4–8 weeks
- 34% reduction in advanced glycation end-products (AGEs)
- Protects both endogenous and newly synthesised collagen from oxidative cross-linking
