PDRN / polynucleotide

What is PDRN / polynucleotide?

Polydeoxyribonucleotide, a DNA fragment ingredient — usually salmon-derived — that moved from aesthetic clinics into Korean skincare and became one of the fastest-growing K-beauty ingredient stories. It is animal-derived, and because of its clinical association the wording of claims needs care: cosmetic claims must stay cosmetic, not medical.
