| How it works | A bio-stimulator. Purified polynucleotides (PDRN) prompt your fibroblasts to repair tissue and improve skin quality over time. | A bio-remodeller. Stabilised hyaluronic acid spreads under the skin, drawing in water and stimulating collagen and elastin. |
| Main ingredient | Polynucleotide chains (PDRN), highly purified. | Hyaluronic acid, thermally stabilised, no chemical cross-linker. |
| Best for | Crepey under-eyes, fine lines, thin or repair-needing skin, skin quality. | Overall hydration, mild laxity and loss of bounce across a wider area. |
| Common areas | Under-eyes, full face, also used for the scalp in hair support. | Face, neck, sometimes hands. |
| Typical course | A course, often two to three sessions a few weeks apart, then maintenance. | A two-session protocol, four weeks apart, then maintenance. |
| Downtime | Minimal. Small injection points, occasional short-lived swelling or bruising. | Minimal. Small raised blebs that settle within about a day, occasional bruising. |
| Price at Melatone | £200 single area, course of 3 from £540. | £450 for the two-session protocol. |
| Skin of Colour | Injectable, not light or acid based, so no melanin-related burn or PIH risk. Suitable across Fitzpatrick I to VI. | Same. An injectable bio-remodeller carries no wavelength or peel-depth risk for darker skin. |
