Hyaluronic Acid vs Palmitoyl Tripeptide-1
A side-by-side research comparison of Hyaluronic Acid and Palmitoyl Tripeptide-1 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Hyaluronic Acid | Palmitoyl Tripeptide-1 |
|---|---|---|
| Full name | Hyaluronic Acid (Sodium Hyaluronate) | Palmitoyl Tripeptide-1 (Pal-GHK) |
| 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). | Functions as matrikine signal, mimicking collagen fragments that trigger fibroblasts to produce new collagen. Palmitoyl enables deeper skin penetration. |
| Molecular weight | Varies widely (kDa to MDa) | 578.8 Da |
| Half-life | Hours to days (tissue turnover) | 8-12 hours (topical) |
| Bioavailability | Topical (surface), oral (systemic), or injectable (local) | Good (topical with lipid modification) |
| Typical dose | Topical serum, ~120-240 mg/day oral, or injectable (provider) | 2-5% in formulation |
| Frequency | 1-2x daily (topical/oral) | 1-2x daily |
| Route | Topical, oral, or injection | Topical |
