PDRN
Best for: tired, dull, ageing or recovering skin that needs regenerative support and a radiance reset.
PDRN (polydeoxyribonucleotide) is one of K-beauty's most-talked-about regenerative actives. Derived from purified salmon DNA fragments (or plant-derived alternatives), it supports skin tissue regeneration, helps reduce inflammation and increases collagen — used clinically in Korea for years before going mainstream in skincare.
