PDRN toners are the cheapest way into the salmon-DNA trend, and the busiest shelf: a single search of one ingredient database on 2 November 2026 returned more than two dozen of them. This page reads what 18 of them declare, sets that against what a toner as a format can deliver, and counts what has been tested. It does not rank the toners and it does not recommend one.
For what PDRN is and the injection evidence, see the PDRN explainer. Why a DNA fragment and a cosmetic peptide behave so differently on skin is set out in how PDRN differs from a peptide in size and evidence, and the PDRN serum label census reads the format where the DNA is most concentrated. For toners of any kind, our peptide toner page counts the evidence for the format itself.
What 18 toners declare
Every list here comes from INCIDecoder on 2 November 2026. That database copies the ingredient list a brand publishes; it is not a lab analysis, and a list copied before a reformulation can be out of date, so treat each row as what was on record that morning. Toner pads and serums were left out, and a toner the database held twice was counted once.

What the table shows that the bottles do not:
- Two "PDRN" toners declare no DNA. Neither the CNP nor the innisfree list contains Sodium DNA, Hydrolyzed DNA or a polynucleotide under any name. On those two, "PDRN" is a word on the front of the pack.
- The DNA ingredient usually sits in the back half. Across the 16 lists that declare one, the median position is 20th; it is in the first ten on only three toners and in the second half of the list on eleven.
- Where an amount is stated, it is tiny. Purito's 5 parts per million is 0.0005 percent: a 200 mL bottle at that strength would hold about one milligram of DNA. Round Lab's 100 parts per million is 0.01 percent, twenty times more and still a hundredth of one percent.
- Half the time the DNA comes after a preservative-level ingredient. Disodium EDTA, a chelator normally used at about 0.1 percent or less, appears on 10 of the 16 DNA-declaring lists, and on five of those (KAINE, both Medicube toners, Round Lab, VT) the DNA ingredient is listed after it. On Dermasil's list it follows phenoxyethanol, a preservative capped at 1 percent in the EU.
- Nine of the 16 are also peptide toners. Anua, Axis-Y, COSRX, Genabelle, KAINE, both Medicube toners, numbuzin and Somethinc list at least one peptide; numbuzin's 125-ingredient list carries several dozen peptide entries. Anything a reader notices after using one of these cannot be put down to the DNA alone.
Reading order as a clue, not a measurement. American cosmetic labels have to rank ingredients by weight only down to the 1 percent mark; below it the brand may list them in whatever order it likes (21 CFR 701.3). So a DNA ingredient that trails disodium EDTA is somewhere under 1 percent, and the list stops there — it cannot tell 0.9 percent from 0.0005 percent. Only the two brands that print a figure close that gap.
What a toner can deliver
A toner is mostly water. It is applied in a thin layer, usually by hand or on a pad, and much of it evaporates. Our peptide toner page found the format's clearest randomized test is a 2019 split-face study of a 6 percent guava-extract toner on oiliness, not on any active's delivery, and that no published study measures how much of any ingredient remains on skin after a toner is applied. That gap applies to DNA exactly as to peptides.
Then there is the molecule itself. Trial preparations of PDRN are long chains, roughly 50,000 to 1,500,000 daltons, while passive passage through healthy skin is generally put at around 500 daltons or less (Bos and Meinardi, 2000) — a gap of a hundred-fold at the very least. A watery film that dries within minutes and is not covered does nothing to narrow it, which is why the covered, wet format of a sheet or hydrogel mask is at least the more plausible topical case on paper; the PDRN mask page weighs that case and where it falls short.
What has been tested
Searching PubMed on 2 November 2026 for any of PDRN, polydeoxyribonucleotide, polynucleotide or sodium DNA alongside the word toner turned up a single paper: six aesthetic practitioners' 2025 consensus on what patients put on their skin around injections (Aesthetic Surgery Journal Open Forum, PMID 41230112). It records expert opinion; it is not a trial and tests no toner.
The closest human evidence for any topical PDRN is a 2026 split-face study of a 0.1 percent PDRN eye cream against 0.1 percent retinol in 31 Chinese women over 28 days (Ye et al., PLoS One, PMID 42430369), whose authors include researchers at two Shanghai biotechnology companies. It used a cream at a stated 0.1 percent, a concentration 10 times Round Lab's toner and 200 times Purito's, and a specific medium-length preparation. Its results do not transfer to a toner.
What can fairly be said
- A PDRN toner is a toner first: water, glycols, glycerin and soothing extracts, with DNA usually in the back half of the list and, where stated, at 0.0005 to 0.01 percent.
- Two products sold under the name declare no DNA at all.
- No trial has tested the format, and no study has measured what stays on the skin after it.
- What is not established is any effect of the DNA in a toner, in either direction.
A reader weighing a toner against a clinic treatment is comparing two different things that share a word; the injection evidence is on our PDRN page and the choice of procedure belongs with the clinician offering it.
