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.
Does Korean skincare work for deeper skin tones?
The skincare does — hydration, barrier support and soothing actives are not tone-specific. The friction points are mineral sunscreens that leave a cast and a colour-cosmetics shade range that has historically been narrow.
