What Is PDRN? The Salmon-DNA Skincare Ingredient, Explained

PDRN stands for polydeoxyribonucleotide — a chain of DNA fragments, most commonly derived from salmon DNA, used in aesthetic medicine and skincare. In cosmetics, PDRN is prized for helping skin look more resilient, elastic, and hydrated, which is why it has become the signature ingredient of the “regenerative aesthetics” movement coming out of Korea.

What does PDRN mean?

Poly-deoxy-ribo-nucleotide: “poly” (many) + “deoxyribonucleotide” (the building blocks of DNA). In practice, PDRN is purified DNA fragments cut to a size skin care formulas can use. The salmon connection isn't marketing whimsy — salmon DNA is structurally similar enough to human DNA to be well tolerated, and it's the most common commercial source. That's why you'll see “salmon DNA” and “PDRN” used almost interchangeably on labels.

Why is PDRN suddenly everywhere?

Three reasons. First, PDRN built its reputation in professional settings — in Korea, injectable PDRN treatments (often called “salmon DNA injections”) became a staple of aesthetic clinics, and ingredients with clinic credibility tend to migrate into home skincare. Second, K-beauty brands translated it into accessible formats — serums, creams, and masks — and several went viral. Third, the results people describe fit what social media rewards: skin that looks plumper, bouncier, and “glass-glow” hydrated.

What is PDRN used for in skincare?

In topical skincare, PDRN is used to support the look of:

• Elasticity and bounce — skin that appears springier and more resilient
• Hydration and glow — a dewy, watered look, especially in hydrogel formats
• Smoothness — a softer-looking texture over time with consistent use

It's worth being honest about the difference between formats: injectable PDRN used in clinics and topical PDRN in a mask or serum are different things. A topical product supports how your skin looks and feels; it is not a procedure, and any brand implying otherwise is overpromising.

Do PDRN masks actually work?

A well-made PDRN mask can visibly hydrate, calm the look of tired skin, and leave skin looking plumper and more luminous — particularly in a hydrogel format, which holds the serum against your skin for 15–30 minutes instead of evaporating out of a fabric sheet. What a mask cannot honestly promise: permanent structural change. Think of PDRN masking as a ritual with a visible payoff, compounding with consistency — not a one-time transformation.

How to choose a PDRN product

• Format matters. Hydrogel masks keep actives in contact with skin longer than fabric sheets.
• Look at the supporting cast. PDRN pairs well with peptides, NAD+, and calming ingredients like arnica.
• Check what's left out. If you have sensitive skin — or you're between aesthetic appointments — look for formulas without exfoliating acids, retinoids, or added fragrance.
• Hygiene format. Single-use sealed masks avoid the contamination issues of jars and multi-use products.

PDRN at LYSIS

Every LYSIS mask — face, under-eye, and V-line chin & jawline — is built on salmon-DNA PDRN paired with NAD+ in a true hydrogel, with arnica in every formula and none of the ingredients aftercare rules warn about: no acids, no retinoids. It's PDRN the way we'd want it used on our own clients: gentle by design, sealed for hygiene, honest about what a mask can do.

PDRN FAQ

Is PDRN vegan? No — it's typically derived from salmon DNA.

Is PDRN safe for sensitive skin? PDRN itself is generally well tolerated; what matters is the full formula. Choose fragrance-free, acid-free products and patch test.

PDRN vs. collagen — which is better? They do different jobs; see our full comparison of PDRN, collagen, and NAD+ on the Journal.

How often should I use a PDRN mask? Once a week is a sustainable ritual; gentle formulas can be used more often before events.
