PDRN, short for Polydeoxyribonucleotide, is a regenerative ingredient derived from DNA fragments, most commonly sourced from salmon, and widely used in advanced Korean skincare. It works by supporting skin repair and regeneration at a cellular level, helping to improve elasticity, reduce fine lines, and accelerate healing. PDRN is especially loved for its ability to restore damaged or stressed skin, making it popular in post-treatment care and anti-aging routines. With consistent use, skin appears firmer, smoother, and more revitalized with a healthy glow.

PDRN is generally well-tolerated, but those with fish allergies should be cautious, and as with any active ingredient, mild irritation can occur in very sensitive skin.
