Does PDRN work? What the cream studies show

PDRN is everywhere right now. 🐟 Toner pads, sheet masks, sunscreens, eye creams. So people ask one simple thing: does PDRN work when you put it on your skin as a cream?

PERBETE read the studies on file and checked hundreds of labels to find out.

What is PDRN in skincare?

PDRN is short for polydeoxyribonucleotide. 🧬 It is a mix of small pieces of DNA, cut to different lengths. On an ingredient list it usually shows up as sodium DNA.

The pieces can come from salmon, from plants like peony, or from tiny microbes. The kinds also differ in how big the pieces are.

Salmon, peony and microbe PDRN all say "PDRN" on the front. The studies below only count for the kind they tested.

PDRN on the front of a box doesn't say which kind is inside. The sodium DNA page keeps everything PERBETE has on it in one place.

Does PDRN work in a cream?

One face study on file looks promising, with some big question marks. 🧪 31 women aged 35 to 55 with sensitive skin used an eye cream with 0.1% salmon PDRN on one side of the face.

They put it on twice a day for 28 days. The other side got the same kind of cream with 0.1% retinol instead.

Reference: Ye et al., 2026

After 28 days, the area and number of crow's-feet lines fell about 20 to 23% on the PDRN side. On the retinol side they fell about 6 to 7%.

No skin reactions were reported. 🙌

Reference: Ye et al., 2026

Now the question marks. 🤔 No side got a plain cream with nothing added, so there is no "did nothing" baseline. The maker of the PDRN supplied it.

Only the eye area was tested, only salmon PDRN, only at 0.1%.

Reference: Ye et al., 2026

So it's a good first sign for one kind of PDRN at one amount, from one study. The same paper also used a lab scanner and saw a PDRN signal show up in the upper layers of skin over time.

If fine lines are your main worry, the wrinkles page ranks ingredients by how much study they have.

What about plant PDRN?

There is a small study on PDRN from peony, a flower. 🌸 10 people used a cream with 1% peony PDRN after a lab test had made their skin barrier weak on purpose.

Over 2 weeks, water loss from the skin dropped 21.0% with the PDRN cream and 14.0% with the same cream without it.

Reference: Bak et al., 2025

The study also looked at skin bounce around the eyes after 4 weeks. Ten people is a very small group, and the authors worked for the company that makes this PDRN. 📝

There are also 8 hand-picked cases of a serum with PDRN from microbes, used after skin treatments. That serum had many other active ingredients too, and the report gives no numbers.

Why don't injection results count here?

A cream and a needle take different routes. 💉 Lots of PDRN news is about injections, where the DNA pieces go straight under the skin. A cream has to get in from the top.

So PERBETE leaves injection studies out when it rates PDRN for skincare.

There is one older study on open skin. After skin was taken for a graft, 20 people got their dressing with a PDRN ointment under it, and 20 people got the dressing alone.

New skin covered the PDRN wounds in 12.5 days, and the others in 24.45 days.

Reference: Valdatta et al., 2004

That was a healing wound, so it says little about a toner pad on everyday skin. 🩹

Where does PDRN sit on the label?

Usually near the bottom. 🔍 On October 29, 2026, PERBETE's catalogue had 734 products listing sodium DNA. Only 18 of them had it in the first five spots of the ingredient list.

337 of those products say PDRN right in the product name. Half of them list sodium DNA at spot 24 or later.

Is that bad? Not by itself! Ingredients go from the biggest amount down. Under one US labeling option, the tiny ones at 1% or less may go in any order after that.

Reference: US Food and Drug Administration, 2016

The cream study used 0.1%, which is in that tiny group. So a low spot fits the amount that was tested.

The spot is a hint about the amount, and it can't tell you the percent. 🏷️

A big PDRN on the box and spot 24 on the list can both be true.

What does PERBETE's PDRN page say about safety?

PERBETE rates sodium DNA 🟢 Low concern for skincare. None of the four cancer lists PERBETE checks includes it: IARC, EU CLP, US NTP and California Prop 65.

Allergy data hasn't been checked yet. For pregnancy it's ⚪ Not rated yet, because PERBETE's research hasn't found a study in pregnant women.

The sodium DNA page shows each source and the full details. 👀
