Hyaluronic Acid vs Matrixyl
A side-by-side research comparison of Hyaluronic Acid and Matrixyl across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Hyaluronic Acid | Matrixyl |
|---|---|---|
| Full name | Hyaluronic Acid (Sodium Hyaluronate) | Matrixyl (Palmitoyl Pentapeptide-4 / Pal-KTTKS) |
| Category | Skin & Anti-Aging | Skin & Anti-Aging |
| Status | OTC / cosmetic / injectable | Research compound |
| Mechanism | Hyaluronic acid binds up to ~1000 times its weight in water, hydrating and plumping the dermal matrix. It supports fibroblast function, tissue repair, and joint lubrication, and its effects depend on molecular weight (low vs high). | Signals through TGF-B pathway to stimulate fibroblast production of collagen I, III, IV, fibronectin, and hyaluronic acid. Palmitoyl chain enhances penetration. |
| Molecular weight | Varies widely (kDa to MDa) | 802.1 Da |
| Half-life | Hours to days (tissue turnover) | 6-12 hours (topical depot) |
| Bioavailability | Topical (surface), oral (systemic), or injectable (local) | Moderate (topical) |
| Typical dose | Topical serum, ~120-240 mg/day oral, or injectable (provider) | 2-8% in serum/cream |
| Frequency | 1-2x daily (topical/oral) | 1-2x daily |
| Route | Topical, oral, or injection | Topical |
