Before comparing PDRN serums, there is something you need to know that almost no review mentions: “PDRN” on the front of a bottle does not guarantee PDRN is inside it.
Real polydeoxyribonucleotide is DNA extracted from salmon or trout milt. That is what the research is on. But the word has become a marketing term, and some products now use plant- or yeast-derived ferment filtrates under the same banner. They are not the same ingredient, they do not have the same evidence, and the front label will not tell you which you are holding.
The INCI list will. Here is what these four actually contain.
The Comparison
| Price | Size | PDRN source | Concentration disclosed | Fragrance | |
|---|---|---|---|---|---|
| Medicube PDRN Pink Peptide Serum | $26 | 30ml | Sodium DNA + Milt Extract (salmon) | Yes — 10,000 ppm (1%) | Yes |
| COSRX 5 PDRN Collagen Intense Vitalizing Serum | varies | — | Sodium DNA (salmon) | No | No |
| Anua PDRN Hyaluronic Acid Capsule 100 Serum | $30 | 30ml | Sodium DNA (salmon) | No | — |
| Mixsoon PDRN Collagen Cream | $25 | 50ml | Rice ferment filtrate (plant) | No | — |
Three of the four use salmon-derived Sodium DNA. One does not.
Medicube PDRN Pink Peptide Serum — the Most Loaded, and the Most Compromised
This is the one driving most of the search interest, and it has the most going on. It lists Sodium DNA and Milt Extract — milt being the actual salmon source material — and it is the only product here that discloses a concentration: 10,000 ppm, which is 1% salmon PDRN. That transparency deserves credit. Nobody else on this list offers it.
It also contains five peptides, which is unusual: Copper Tripeptide-1 (GHK-Cu), Acetyl Hexapeptide-8 (Argireline), Palmitoyl Pentapeptide-4, and Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 (together, Matrixyl 3000). That is essentially every well-known cosmetic peptide in one bottle.
Which brings us to the problem.
The second ingredient on the list is Disodium EDTA — a chelating agent. Chelators bind metal ions. Copper Tripeptide-1 is a peptide whose entire function depends on holding onto a copper ion. Chelating agents at meaningful levels can strip copper directly from the tripeptide. Having EDTA that high in the list, in a product whose selling point includes a copper peptide, is a formulation choice worth questioning. We explain the chemistry in GHK-Cu explained.
It also contains Fragrance, plus Isopropyl Myristate and Sorbitan Oleate, both of which carry pore-clogging risk for acne-prone skin. Its user rating on Skinsort sits at 2.86 out of 5 across 29 reviews — notably lower than the marketing volume around it would suggest.
One more thing: Medicube sells several PDRN products, and they do not all use the same source. At least one listing markets a vegan “Rose PDRN” version. Check the INCI on the specific bottle you are buying, not the brand.
Verdict: the most interesting formula and the only disclosed concentration, undermined by an EDTA placement that fights one of its own headline ingredients. Good if you want the PDRN and are not buying it for the copper peptide.
Medicube also makes a PDRN eye serum in the same line, using the same salmon DNA base in a formula aimed at the under-eye.
COSRX 5 PDRN Collagen Intense Vitalizing Serum — the Sensible One
Thirty-eight ingredients, built around Sodium DNA, niacinamide, five forms of hyaluronic acid, hydrolyzed collagen and adenosine.
No fragrance. No pore-clogging ingredients flagged. No copper peptide, so no chelation conflict to worry about. It does not disclose PDRN concentration, which is a real gap.
This is the least exciting formula here and probably the most sensible one. It does one job — hydration and barrier support with PDRN — without stacking six actives that may interfere with each other. For anyone with reactive or acne-prone skin, this is the pick.
Verdict: the safe default. Best choice if you are trying PDRN for the first time.
Anua PDRN Hyaluronic Acid Capsule 100 Serum — the Hydration Play
$30 for 30ml, the most expensive per millilitre on this list. Sodium DNA alongside multiple forms of hyaluronic acid — hydrolyzed HA, sodium hyaluronate, potassium hyaluronate and crosspolymer versions — plus collagen, niacinamide and a set of botanical extracts including turmeric, neem and coptis root. Delivered via microcapsule technology.
Anua’s own testing claims an 8.93% improvement in hydration after a single use. Treat brand-run testing as directional rather than proof, but the formula is clearly built around moisture rather than repair.
Verdict: buy it for hydration and plumping. If you want PDRN for barrier recovery specifically, this is the most targeted of the four — you are just paying a premium for it.
Mixsoon PDRN Collagen Cream — Not Actually PDRN
$25 for 50ml, which is the best value per millilitre here. It also contains Copper Tripeptide-1, low-molecular collagen and niacinamide, and it is a cream rather than a serum, which suits drier skin.
But the PDRN is “plant-based PDRN derived from rice” — listed as Saccharomyces/Rice Ferment Filtrate. That is a yeast-fermented rice ingredient. It is not polydeoxyribonucleotide from salmon or trout, and the human and animal research on PDRN does not transfer to it.
Rice ferment filtrates are not bad ingredients. They are hydrating, they contain amino acids and they have their own modest literature. The objection is to the naming. If you are buying this because you read about PDRN’s effects on collagen and wound healing, you are not buying the thing you read about.
Verdict: a decent, good-value niacinamide-and-collagen cream. Vegan, which the others are not. Just do not buy it as a PDRN product.
How to Read a PDRN Label Yourself
- Find the INCI list. Ignore the front of the box entirely.
- Look for Sodium DNA or Milt Extract. These are real, salmon- or trout-derived PDRN.
- Treat Ferment Filtrate as a different ingredient. Rice, yeast or other plant ferments marketed as “PDRN” or “PDRN-like” are not polydeoxyribonucleotide.
- Check where it sits. High in the list means meaningful; buried after the preservatives means trace.
- Prize disclosed concentrations. A brand stating “10,000 ppm” is telling you something. A brand saying “with PDRN” is not.
What to Realistically Expect
All four of these are topical products, and topical PDRN has a genuine penetration problem — PDRN fragments run from 50,000 daltons upward, far above the rough 500-dalton threshold for passive absorption. The strong clinical results for PDRN come from injections, not serums.
So: expect barrier comfort, better hydration, calmer redness, and a plumper look over a few weeks. Do not expect a serum to reproduce a clinic skin-booster result. We go into why in What is PDRN?
If your goal is structural — firmness, fine lines, density — the better-evidenced topical is GHK-Cu, and we compared the two directly in PDRN vs. copper peptides.
Frequently Asked Questions
Which one should I start with?
COSRX. Fragrance-free, no ingredient conflicts, salmon-derived PDRN, and it does not depend on six actives cooperating.
Is Medicube worth the hype?
The PDRN content is real and disclosed, which is more than its competitors offer. The five-peptide stack is less convincing than it sounds given the EDTA placement, and the fragrance rules it out for sensitive skin.
Is there a vegan PDRN serum?
Not a true one — PDRN is by definition animal-derived. Mixsoon’s rice ferment and Medicube’s “Rose PDRN” listing are vegan alternatives to PDRN, not vegan PDRN.
Can I use a PDRN serum with retinol or acids?
Yes. PDRN is non-acidic and non-stripping, and it is often recommended alongside strong actives to buffer irritation. Apply the PDRN after the active has absorbed.
Why does nobody list the percentage?
Because they are not required to, and because PDRN is expensive. A brand that discloses is usually a brand with something to disclose.
