What Is PDRN in Skincare? The Korean Beauty Trend Explained

PDRN, short for polydeoxyribonucleotide, has become a prominent term in Korean beauty marketing. Many cosmetic formulas use salmon-derived PDRN alongside familiar hydrating and soothing ingredients.

What Topical PDRN Products Are

In skincare, PDRN appears in toners, ampoules, serums, masks, and creams. The finished product may also contain glycerin, hyaluronic acid, niacinamide, peptides, or barrier-supporting emollients that contribute to how the skin feels and looks.

What to Expect

A well-formulated product may support hydration and a smoother, more luminous appearance. However, topical cosmetics should not be assumed to provide the same effects as injectable or professional procedures.

How to Add It to a Routine

Apply a PDRN serum or ampoule after toner and before moisturizer. Start once daily or a few times per week, depending on the rest of your routine. Use sunscreen every morning when your goal includes a more even-looking complexion.

People with fish allergies or highly reactive skin should review product information carefully and seek professional advice when appropriate. Patch test before regular use.
