What is PDRN?
PDRN stands for polydeoxyribonucleotide, a chain of DNA fragments most commonly sourced from salmon, because it is highly compatible with human skin. In professional settings it has long been used to support wound healing and tissue repair. In skincare, that same regenerative reputation is harnessed to help tired, ageing or stressed skin look healthier, plumper and more resilient.
What does PDRN do for skin?
PDRN is prized for three things: supporting the skin's natural repair and renewal, boosting deep hydration for a plumper look, and helping improve elasticity and firmness over time. People reach for it when they want a recovery and anti-ageing boost without harsh actives, because it tends to be gentle and hydrating rather than irritating.

Who should use PDRN?
PDRN suits anyone wanting a recovery and firmness boost: dull, tired or stressed skin, early signs of ageing, or skin recovering from actives. Because it is gentle and hydrating, it also works for sensitive skin that cannot tolerate strong retinoids. It layers easily into almost any routine.

Frequently asked questions
Is PDRN really made from salmon?
Yes, PDRN is typically derived from salmon DNA, which is highly compatible with human skin. It is purified for cosmetic use and prized for its regenerative, skin-repairing reputation.
Is PDRN safe for sensitive skin?
Generally yes. PDRN is known for being gentle and hydrating rather than irritating, which makes it a popular alternative for those who find retinoids too harsh. Patch test any new product first.
Can I use PDRN with other actives?
Yes. PDRN layers well and can even support skin recovering from stronger actives. Apply thinner, watery products first, then richer ones, and use SPF in the morning.
How long until PDRN shows results?
Hydration and a plumper look can appear within days, while firmness and elasticity build over several weeks of consistent use.
