PDRN (polydeoxyribonucleotide) is a skincare ingredient made from DNA fragments, usually sourced from salmon, that became one of Korea's biggest beauty trends for bouncy, revitalised-looking, glass-like skin. In cosmetics, it is found in toners, serums, essences, masks and even scalp gels.
What is PDRN?
PDRN stands for polydeoxyribonucleotide, a mix of DNA fragments. Korean clinics first popularised it in professional treatments, nicknamed "salmon DNA" facials. Skincare brands then brought PDRN into at-home formulas, often alongside peptides and hydrators.
What does PDRN do in skincare?
In cosmetic products, PDRN is used to help skin look and feel:
- more hydrated and plump
- smoother and bouncier
- more radiant and revitalised
Results depend on the whole formula and consistent use. Cosmetic PDRN products are not medical treatments.
PDRN vs. peptides vs. exosomes
| Ingredient | What it is | Best for |
|---|---|---|
| PDRN | DNA fragments | Bounce, hydration, glow |
| Peptides | Short amino-acid chains | Firmer, smoother-looking skin |
| Exosomes | Cell-derived vesicles | Renewed-looking skin |

How to use PDRN in your routine
- Cleanse.
- Apply a PDRN toner or toner-serum, such as the Cosmecell PDRN & Copper Peptide Toner Serum.
- Follow with a targeted serum; for the jaw and neck try the PDRN Jawline Contour Serum.
- Moisturize, then use SPF in the morning.
Who is PDRN skincare for?
PDRN suits most skin types, especially dry, dull or mature-looking skin. If you avoid fish-derived ingredients, check the ingredient list, as most PDRN is salmon-derived.
