Hyaluronic Acid vs Palmitoyl Tetrapeptide-7
A side-by-side research comparison of Hyaluronic Acid and Palmitoyl Tetrapeptide-7 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Hyaluronic Acid | Palmitoyl Tetrapeptide-7 |
|---|---|---|
| Full name | Hyaluronic Acid (Sodium Hyaluronate) | Palmitoyl Tetrapeptide-7 (Pal-GQPR) |
| 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). | Inhibits IL-6 release from keratinocytes and reduces inflammation-mediated MMP activation, preserving existing collagen while complementing Pal-GHK collagen building. |
| Molecular weight | Varies widely (kDa to MDa) | 693 Da |
| Half-life | Hours to days (tissue turnover) | 8-12 hours (topical) |
| Bioavailability | Topical (surface), oral (systemic), or injectable (local) | Good (topical) |
| Typical dose | Topical serum, ~120-240 mg/day oral, or injectable (provider) | 2-4% in formulation |
| Frequency | 1-2x daily (topical/oral) | 1-2x daily |
| Route | Topical, oral, or injection | Topical |
