If you have been on skincare TikTok lately, you have seen "salmon DNA" everywhere. It sounds intense, but it is one of the most loved hydrating ingredients in Korean skincare.
What is PDRN?
PDRN stands for polydeoxyribonucleotide — a fragment derived from salmon DNA, chosen because it is remarkably similar to human DNA and very well tolerated by skin. In cosmetics it is prized as a deeply hydrating, soothing ingredient that helps skin look plump, bouncy, and refreshed.
What people love it for
- A dewy, "just-left-the-facial" glow — it floods skin with moisture.
- Plump, bouncy-looking skin — great for dullness and tired skin.
- Comfort — gentle enough to be a favorite for post-treatment care.
(These are cosmetic, appearance-level benefits — PDRN skincare hydrates and improves how skin looks and feels.)
How to use it
- Daily booster: pat 2–3 drops onto damp skin after cleansing. (Curenex Daily Skinbooster)
- Ampoule: a weekly deep-hydration treatment. (Salmon Skin Rejuvenation)
- For stressed skin: PDRN + EGF complex. (SD Control)
