PDRN stands for Polydeoxyribonucleotide.
It is a DNA-derived ingredient originally used in medical and aesthetic treatments
to support skin healing and regeneration.
In skincare, PDRN is used to help repair damaged skin
and improve overall skin condition.
2. Where Does PDRN Come From?
Most cosmetic-grade PDRN is extracted from salmon DNA
