PDRN Skincare May Support Skin, But Hype Needs Perspective
PDRN is an ingredient made from purified, very small DNA pieces.
It is often made using salmon or trout DNA.
Skincare companies put it in products such as serums, creams and masks.
It may help skin hold moisture and support its natural repair process.
This could make skin look smoother, calmer and more hydrated.
Doctors say creams and serums do not work as deeply as professional injections.
The research on topical PDRN is still growing, so results may be modest and gradual.
It can be useful in a gentle routine, but it cannot replace sunscreen, moisturiser or treatment from a dermatologist.
PDRN, or polydeoxyribonucleotide, consists of purified DNA fragments commonly derived from salmon or trout.
Medical-grade PDRN has been investigated for tissue repair, wound healing, regeneration and inflammation management.
Topical products may support hydration, the skin barrier, recovery and smoother-looking texture, but evidence remains developing.
Dermatologists say topical PDRN is not equivalent to injectable treatment and should not be viewed as a miracle skin rebuilder.
PDRN may suit dry, sensitive, mature or stressed skin, but it does not treat acne or replace sunscreen, moisturiser or medical care.
