PDRN (Sodium DNA)
sodium dna
In short
Sodium DNA is a marine‑derived polynucleotide used for deep hydration and improved skin suppleness. It helps bind moisture and can support a plumper, more elastic look.

What it is
DNA fragments, classically salmon-derived, studied for skin recovery. Most published human evidence comes from in-clinic injections, not creams; the first small topical studies appeared in late 2025 and are directional rather than conclusive. Whether enough reaches living skin layers from a serum is the open question.
Where it sits
Serums sit after toner and before moisturiser. Thinnest to thickest, water before oil.
