What Is PDRN? Korean Skincare Ingredients and Evidence (2026 Guide)
Last updated: September 2026 | Written by the COLORCITY editorial team
PDRN appears in a growing range of Korean toners, serums, creams and eye products. The ingredient source and complete formula vary between products.
But what is PDRN? Why is it called “salmon DNA”? Does it actually work, or is it just another K-beauty marketing wave?
This guide explains what PDRN is, what the evidence can tell us, and how to compare eight product formats at COLORCITY.
What is PDRN?
PDRN means polydeoxyribonucleotide, a DNA-derived ingredient. Some products use salmon-derived material, while others use plant-derived material. Purito, for example, identifies the PDRN in its Oat toner as oat-derived. Check the specific formula rather than assuming every PDRN product contains salmon DNA.
What does the research show?
Research covers different preparations and delivery methods. A 2026 randomized, double-blind, split-face study compared a specific 0.1% PDRN-850K eye cream with 0.1% retinol over 28 days and reported improvements in measured eye-area parameters. Its results concern the tested preparation; they do not establish the same benefits for every PDRN cosmetic.
Injection studies and laboratory findings also cannot establish a guaranteed result from applying a retail serum. Evaluate evidence for the finished product, its concentration and its method of use. This guide does not promise a percentage improvement, wound healing or a fixed time to results.
How to compare PDRN products
- Product format: choose a toner, serum or moisturiser that fits your existing routine.
- Complete ingredient list: consider moisturising ingredients, fragrance, exfoliants and retinoids alongside the PDRN.
- Source: check the manufacturer's information if animal-derived ingredients matter to you.
- Skin tolerance: introduce a new product gradually and follow its directions. Irritated skin or skin recovering from a procedure needs individual advice.
How to use PDRN in your routine
Follow the directions for the finished product. A typical sequence is cleansing, an optional toner, serum, moisturiser and daytime sunscreen. You do not need a PDRN product at every step.
There is no universal five-minute wait that makes every PDRN combination suitable. When using exfoliants or retinoids, consider the whole routine and your skin's tolerance rather than adding multiple new products together.

Common questions about PDRN
Is it the same as hyaluronic acid?
No. They are different ingredients and may appear together in a formula. Check the full product composition rather than attributing every effect to PDRN.
Does every PDRN product contain salmon DNA?
No. Sources vary. Purito's Oat toner uses oat-derived PDRN; Anua identifies its Capsule 100 Serum PDRN as salmon-derived. Check the exact product if ingredient origin matters to you.
Can I use PDRN with retinol?
Compatibility depends on the complete products and your skin's tolerance. Follow their directions and introduce one new product at a time.
Can I use it during pregnancy or breastfeeding?
Ask your clinician to review the exact formula. PDRN on the label does not establish pregnancy or breastfeeding safety. Read the AAD pregnancy skincare guidance.
How long until I see results?
There is no shared timeline for these different formulas. Assess the evidence for the particular finished product and avoid treating hydration or texture changes as proof of tissue repair.
What if my skin is sensitive or recovering from a procedure?
Check all ingredients and follow your clinician's aftercare advice. Do not use this product comparison as a treatment plan for eczema, rosacea, burns or recently treated skin.
Can I use a facial product on my body?
Follow the product's labelled application areas and directions.
Choosing a product
Compare format, ingredients and directions first. Research into a specific PDRN preparation can inform a discussion, but it does not guarantee the performance of a different retail formula.
