PDRN has moved from professional-treatment conversations into Korean cosmetic serums. A topical serum is not the same as an injectable treatment: judge it as a complete skincare formula, including its humectants, texture and tolerability, rather than assuming one headline ingredient guarantees a dramatic result.

Frequently asked
What is PDRN in Korean skincare?
In topical cosmetics, PDRN is used as a formula ingredient in products marketed for hydration and a smoother, more elastic-looking finish.
Is a PDRN serum equivalent to an injectable treatment?
No. A topical cosmetic and a professional injectable treatment have different delivery, regulation and evidence.
Where does PDRN serum go in a routine?
Apply it after toner and before moisturiser, using sunscreen as the final morning step.
Is every PDRN serum the same?
No. Concentrations, ingredient sources, supporting humectants and overall formulas differ, so compare the full product rather than the label alone.
