← The FormularySkin & facePDRN
Also known as PolydeoxyribonucleotideThe face card. It never declines.
PDRN is the ingredient every Korean 'glass skin' routine is quietly built on, and it's having a moment for real reasons — but the human data is still young. Treat it as a very promising hydrator-slash-recovery active, not a proven miracle. The glow is real. The forever-claims are running ahead of the science.
A salmon-derived nucleotide ingredient popular in Korean 'glass skin' skincare.
PDRN is a fragment of salmon DNA — yes, really — whose building blocks are close enough to ours that skin recognises them. It's studied for supporting hydration, a calmer-looking surface and that lit-from-within finish. Think of it as skincare that speaks the skin's own language.
Used in serums to support a hydrated, refreshed, more radiant-looking complexion.
Anyone chasing the dewy, 'I slept eight hours' look — especially after a stretch of very much not sleeping eight hours. It plays well with almost everything, which makes it an easy daily driver.
Two to four pumps on clean skin, morning and night, before your heavier creams. It layers cleanly under and over most things. No purge, no sun-sensitivity, no drama.
Hydration and a fresher, more radiant surface within a couple of weeks. It's a 'looks well-rested' active, not a resurfacing one — steady, not dramatic.
Emerging cosmetic evidence with strong early-clinical and anecdotal support out of Korea. The Grade C reflects how new the human research is — not whether people love it. They do.
Evidence grades describe how well an ingredient is studied — A well-supported, C emerging — not a promise of results. Educational, not medical advice. Doses are typical ranges; follow the label on the product.
