- Palmitoyl Pentapeptide-4 (Matrixyl)
- TGF-β pathway activation → collagen synthesis
- 4–8%
- Lyophilized at −20°C; reconstituted at 2–8°C for ≤28 days
- 30–40% wrinkle depth reduction at 90 days
- Photoaging, fine lines, loss of dermal density
- Acetyl Hexapeptide-8 (Argireline)
- SNARE complex inhibition → reduced muscle contraction
- 8–10%
- Lyophilized at −20°C; reconstituted at 2–8°C for ≤21 days
- 17–30% expression line depth reduction at 30 days
- Dynamic wrinkles (crow's feet, forehead lines)
- Copper Tripeptide-1 (GHK-Cu)
- Copper ion delivery → lysyl oxidase activation → collagen crosslinking
- 1–3%
- Lyophilized at −20°C; reconstituted at 2–8°C for ≤14 days (copper catalyzes oxidation)
- 20–35% elasticity improvement at 60 days
- Photodamage, loss of firmness, wound healing research
- Palmitoyl Tripeptide-38 (Matrixyl synthe'6)
- Matrikine signaling → increased synthesis of collagen I, III, IV, fibronectin
- 2–4%
- 25–31% wrinkle volume reduction at 56 days
- Deep wrinkles, loss of dermal architecture
