PDRN (Salmon DNA)
Scientific name: Polydeoxyribonucleotide · Repair, anti-inflammatory, collagen support, brightening
PDRN, short for polydeoxyribonucleotide, is a repair-focused active usually derived from salmon DNA. It became one of the biggest K-beauty trends for its reputation around skin recovery, elasticity, and a plumped, revived look. Korean serums and masks build entire ranges around it.
Polydeoxyribonucleotide (PDRN) is a purified collection of DNA fragments, primarily extracted from chum salmon or trout sperm cells, used in medicine since the 1990s for wound healing and tissue repair. In K-Beauty it activates the A2A adenosine receptor to reduce inflammation, upregulates VEGF and collagen synthesis, inhibits MMP-2/9 and MITF (pigmentation), and feeds the DNA salvage pathway. Injectable PDRN (Rejuran Healer) has the strongest evidence for structural remodeling; topical PDRN delivers hydration, barrier repair and anti-inflammatory benefits, with stronger results when combined with delivery-enhancing technology like the VT Reedle Shot spicule system.

{"Avoid VT Reedle Shot (spicule delivery) during active dermatitis flares or when the skin barrier is compromised","Salmon-derived PDRN is not vegan; ginseng or yeast-derived vegan PDRN has a smaller evidence base","Topical PDRN cannot replicate injectable Rejuran clinic results"}

Frequently asked questions
› What is PDRN and what does it do?
PDRN is polydeoxyribonucleotide, a fragment of DNA usually sourced from salmon. In skincare it is used for its reputation around skin repair, hydration, and a plumper, more elastic-looking finish over time.
› Is PDRN the same as the salmon DNA in facials?
They share the same active idea. Clinics use injectable forms; topical K-beauty PDRN serums use it on the skin surface, so the effect is gentler and more about hydration and a revived look.
› Who should use PDRN?
It suits people wanting a plumped, revived, more elastic look, especially tired or early-aging skin. Because it is salmon-derived, it is not vegan and anyone with a fish allergy should avoid it.
› How do I use a PDRN serum?
Apply after toner, before moisturiser, morning or night. It layers well with hydrating and barrier ingredients, and you can pair it with peptides for a firming-focused routine.
