Microneedling With Salmon DNA (PDRN): What to Know

PDRN is a mixture of DNA fragments, and some skincare products source it from salmon. Research on topical PDRN is early. Putting any product on freshly needled skin adds risk: the FDA has not cleared any microneedling device for use with another product.

What PDRN is

PDRN, or polydeoxyribonucleotide, is described in research as a mixture of DNA fragments. Salmon is the source most often named for it, and researchers are now testing plant-based versions as an alternative (1). The phrase "salmon DNA" on a label is often used for a salmon-derived ingredient. This page covers it only as a cosmetic ingredient applied to the skin.

One seller's page for a product with a PDRN complex describes it as a cosmetic for skincare use, and says it is not intended to diagnose, treat or prevent any disease (6).

Why the combination raises a question

Microneedling opens tiny channels in the skin. Whatever is applied right afterward meets skin that is more open than usual. The FDA has not reviewed that combination for any product (3).

What studies exist

  • A 2026 study of one topical PDRN preparation combined lab work on skin cells, delivery tests in lab and skin models, tests on skin samples exposed to ultraviolet light, and a 28-day randomized, double-blind split-face comparison of a 0.1% PDRN eye cream with 0.1% retinol. The authors report support for it as a topical approach for sun-damaged skin (2).
  • A 2025 study tested a plant-derived PDRN in the lab and in small human tests. In 10 people, a 2-week topical use reduced water loss through skin that had been irritated, and a separate test reported better periorbital skin elasticity after 4 weeks (1).

These are early studies of single preparations. They do not show that a particular product works, and none tested PDRN applied together with microneedling.

What is not known

  • Whether PDRN applied with microneedling does anything extra.
  • Whether a given product is sterile and suitable for punctured skin.
  • Whether salmon-derived and plant-derived PDRN behave the same way.
  • How long any effect would last.

Before you use any product with needles

The FDA says it has not cleared any microneedling device for use with another product (3). A 2025 case report describes a necrotic ulcer on the chin after a woman used an oil with an at-home device (5). See how to read a label on the serum page, and ask your professional before applying anything to skin that has just been treated.

Common questions

Is PDRN the same as salmon DNA?

Not exactly. PDRN stands for polydeoxyribonucleotide, a mixture of DNA fragments. Salmon is one source; a 2025 study proposes a plant-based alternative to salmon-derived PDRN (1). Product names often blur the terms, so check the ingredient list and ask where it comes from.

Can I put it on right after microneedling?

Ask your professional first. The FDA says it has not cleared any microneedling device for use with another product, so it has not reviewed the safety or effectiveness of combining them (3). A 2021 review cautions about products not intended to be applied with microneedles (4).

Does PDRN work?

The research is early. The two studies we cite tested single preparations, mostly in the lab and in small human tests. They are not proof that any product on the market works, and they say nothing about using it with needles.
