Comparison table
| Attribute | Matrixyl | Palmitoyl Tripeptide-1 |
|---|---|---|
| Full name | Matrixyl (Palmitoyl Pentapeptide-4 / Pal-KTTKS) | Palmitoyl Tripeptide-1 (Pal-GHK) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | Research compound | Research compound |
| Mechanism | Signals through TGF-B pathway to stimulate fibroblast production of collagen I, III, IV, fibronectin, and hyaluronic acid. Palmitoyl chain enhances penetration. | Functions as matrikine signal, mimicking collagen fragments that trigger fibroblasts to produce new collagen. Palmitoyl enables deeper skin penetration. |

| Half-life | 6-12 hours (topical depot) | 8-12 hours (topical) |
| Bioavailability | Moderate (topical) | Good (topical with lipid modification) |
| Typical dose | 2-8% in serum/cream | 2-5% in formulation |
| Frequency | 1-2x daily | 1-2x daily |
| Route | Topical | Topical |
