What Is PDRN in Skincare?
PDRN, Explained
A modern skin-conditioning ingredient for smoother, refreshed-looking skin.
PDRN has become one of the most talked-about ingredients in modern skincare. Learn what PDRN is, what current research suggests, and how it fits into a simple daily skincare ritual.
What Is PDRN?
PDRN stands for polydeoxyribonucleotide. It is a purified mixture of DNA fragments studied in dermatology, tissue care, and aesthetic science.
PDRN is often associated with purified DNA from salmon or trout sources, although its exact source and composition may vary between formulas.
In topical skincare, PDRN is best understood as a skin-conditioning ingredient designed to support the appearance and feel of the skin.
The Evidence Behind PDRN
Promising Research, With Important Context
A 2026 systematic review examined 7 randomized clinical trials involving 183 participants. Among these studies, 4 investigated polynucleotide treatments and 3 investigated PDRN-based treatments. Read the 2026 systematic review
The studies covered:
- 4 studies on aesthetic skin rejuvenation
- 1 study on postoperative scar care
- 2 studies on wound-healing applications
Study sizes ranged from 10 to 42 participants, with follow-up periods ranging from 2 weeks to 6 months.
The review reported promising findings, but also noted that the studies used different formulas, treatment methods, and evaluation standards. Larger studies are still needed.
An earlier systematic review examined more than 90 publications and included 34 laboratory, animal, and clinical studies related to PDRN and tissue repair. Read the 2020 systematic review
These findings describe PN/PDRN clinical research and should not be presented as clinical proof of this specific serum.
How Does PDRN Work?
Research has explored PDRN in relation to adenosine A2A receptor signaling and nucleotide salvage pathways. Read the dermatology mechanism review
For topical skincare, the final experience depends on the complete formula, concentration, stability, skin compatibility, and delivery system.
PDRN should not be described as repairing DNA, regenerating cells, or treating skin disease.
What Can PDRN Support?
Smoother-Looking Skin
PDRN can be part of a consistent skincare routine designed to support a smoother, more refined-looking complexion.
Hydrated Skin
Combined with moisturizing ingredients, PDRN can support soft, comfortable, hydrated-looking skin.
Refreshed Radiance
A well-formulated serum can help tired-looking skin appear fresher, brighter, and more even.
Simple Steps
01. Cleanse
Use 1–2 pumps of cleanser with lukewarm water for 20–30 seconds, then gently pat your skin dry.
02. Apply
Apply 2–3 drops of PDRN serum to your face and neck, gently pressing it in for 30–60 seconds, once or twice daily.
03. Moisturize
Finish with 1–2 pumps of moisturizer to help maintain a comfortable, hydrated-looking finish.
PDRN Serum vs. Injectable Treatments
Topical PDRN skincare and injectable PDRN treatments are not the same.
A serum is designed for an at-home skincare routine. Injectable treatments are professional procedures that require qualified clinical care.
Our serum is designed to support the appearance and feel of the skin. It is not intended to diagnose, treat, cure, or prevent any disease.
