PolydeoxyribonucleotideModerate evidence3 citations

The "salmon DNA" trending in K-beauty and Korean clinics. Strong wound-healing pedigree translated into anti-aging. Speeds repair after lasers/microneedling, smooths fine lines, and brightens. Often layered with vitamin C and niacinamide. Worth knowing: salmon- or trout-derived PDRN has much stronger clinical evidence than plant ("phyto") PDRN, and the dose matters more than the marketing — favor products that list a real PDRN concentration (roughly 1,000+ ppm) over big headline numbers on plant-derived versions.
