For your skin
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.

Low-MW DNA fragments (50-1500 kDa) isolated from salmon trout sperm that activate adenosine A2A receptors on fibroblasts, driving VEGF release, collagen synthesis, and accelerated wound repair while supplying salvage-pathway nucleotides.
Why we tier this anecdotal
4 cited papers across 2 countries. Most of what's cited here is mechanism-level or in-vitro work. We track this as Anecdotal until controlled clinical trials accumulate.
