How PDRN (Salmon DNA) works ์ฐ์ด DNA
PDRN (polydeoxyribonucleotide, often from salmon) is a DNA-fragment mixture. In injectable/clinical use it is studied for tissue repair signaling, but as a topical cosmetic its large molecules have limited penetration, so its on-skin role is mainly as a hydrating, film-forming conditioner that supports a plump, bouncy look. Topical evidence is emerging and distinct from injectable data.

What is PDRN or salmon DNA in skincare?
PDRN (polydeoxyribonucleotide), sometimes called salmon DNA, is an ingredient trending in Korean skincare and aesthetic treatments, marketed for a smoother, more revitalized look. In cosmetics its effects are described in appearance terms; stronger claims belong to clinical procedures, not over-the-counter products.
How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
