Skincare, simply explained
PDRN is used in Korean skincare for a smoother, more supple appearance. You’ll find it in moisturizing serums, masks and creams designed for fine-line care and skin that feels dry.
Some PDRN creams may help soften the look of fine lines around the eyes.
Some topical PDRN preparations may support skin elasticity: the quality behind a springy, supple feel.
Certain PDRN preparations may help skin hold on to moisture, making them an interesting addition to moisturizing care.
PDRN stands for polydeoxyribonucleotide, a long name for a mixture of DNA fragments. DNA is made of chains of smaller units; PDRN preparations contain shorter sections of those chains. In skincare, these ingredients are processed and purified for use in cosmetic formulas.
The source can be animal or plant material. Fish-derived preparations are familiar, while researchers have also developed plant-derived materials, including one from peony.
Names such as Sodium DNA, Hydrolyzed DNA and Hydrolyzed Sodium DNA identify related cosmetic forms. Hydrolyzed means the material has been broken into smaller pieces. These names do not specify the original source, so the brand’s ingredient information is useful if that matters to your choice.
On the ingredient list: Sodium DNA, Hydrolyzed DNA or Hydrolyzed Sodium DNA
Also known as: Polydeoxyribonucleotide
Choose a cosmetic made for ordinary surface use: a serum, cream or mask. Check its directions and ingredient list.
Apply a serum after cleansing and watery layers, before moisturizer. Follow the specific instructions for masks and creams.
Introduce one product at a time and use it as often as the label recommends.
Keep your basics in place: gentle cleansing, enough moisturizer and daytime sunscreen.
A few thoughtful pairings can help you build a comfortable routine.
A practical partner for a light, hydrating skincare step.
Fits a routine focused on moisture and comfort.
A useful moisturizing finish after a serum.
A 2026 study tested a defined PDRN eye cream over four weeks and reported improvements in fine-line measurements.
Researchers have also studied PDRN prepared from peony, with small human studies of moisture loss and elasticity. Check the brand's sourcing information if you prefer a plant-derived product.
Polydeoxyribonucleotide. In plain language, it is a mixture of DNA fragments used in some skincare formulas.
No. Fish-derived materials are common, but plant-derived preparations have also been studied. Check the manufacturer's source information rather than guessing from the ingredient name.
Not automatically. You need the source of the DNA ingredient and confirmation about the rest of the formula. A plant-derived PDRN claim alone does not verify the whole product.
Early topical human studies concern specific DNA preparations and delivery systems. They do not establish shared results across all Sodium DNA or Hydrolyzed DNA cosmetics, or equivalence to injected PDRN.

Small, short split-face study of a defined PDRN-850K eye cream against retinol. Fragment preparation and delivery matter; this does not establish results for every DNA ingredient or equivalence to an injection.

A specialized plant-derived preparation; small human studies reported moisture-loss and eye-area elasticity changes. Not evidence that all PDRN is plant-derived or shares these results.

Explains hydrolysis and identifies the cosmetic conditioning ingredient. The label alone does not establish biological source, fragment length or equivalence to an injectable preparation.

Practical guidance for testing the complete product, not a guarantee against allergy.
No. Surface application and injection are different routes. A serum should be judged on evidence for that topical product, not the results of a clinic treatment.
Use your product as directed. Many ordinary serums and creams fit daily routines, but a mask or treatment may have a different schedule.
Give your routine several weeks and assess how your skin looks and feels. Early topical studies have followed changes over two to four weeks.
Find your next routine favourite
Start with one product that fits your routine.
Use at your serum step, before moisturizer. Choose this step when you want to keep the cream you already love, and follow the product's directions for how often to apply it.
Explore a serum or ampouleMake it part of your moisturizing step. Choose a cream for a richer finish or an emulsion for a lighter layer.
