PDRN vs Polynucleotides: Which One Actually Suits Your Skin? (NZ Guide)
Two ingredients, one question: which does what for the look of your skin, and do you need both? Here is polynucleotides (PN, the clinic version) beside PDRN, plainly.
| PDRN | Polynucleotides | |
|---|---|---|
| What it is | PDRN is polydeoxyribonucleotide: DNA cut into short fragments, in skincare almost always from salmon. It arrived in Korean skincare and is now on New Zealand shelves in serums and ampoules. | The same family of DNA fragment ingredients as PDRN, in longer chains. In clinics, polynucleotides are injected; in skincare, PN on a label means a topical version that sits on the surface like any other serum. |
| What it is for | A PDRN serum is used for the look of plumper, more hydrated, smoother skin. The visible part is hydration: a well made PDRN serum sits on a humectant base and skin looks fuller while you use it. | On the skin, a PN serum behaves like a PDRN serum: skin looks more hydrated and plumper while you use it. The injected version is a different thing entirely and not something a serum can imitate. |
| How it feels | Watery, light, settles in about a minute. It is the kind of serum that suits a roller. | Watery serums and ampoules, very like PDRN products. |
| When to use it | Night, on clean dry skin, most nights. | Night, on clean skin, like PDRN. |
What polynucleotides is
The same family of DNA fragment ingredients as PDRN, in longer chains. In clinics, polynucleotides are injected; in skincare, PN on a label means a topical version that sits on the surface like any other serum.
What polynucleotides does for the look of skin
On the skin, a PN serum behaves like a PDRN serum: skin looks more hydrated and plumper while you use it. The injected version is a different thing entirely and not something a serum can imitate.
PDRN, briefly
PDRN is polydeoxyribonucleotide: DNA cut into short fragments, in skincare almost always from salmon. It arrived in Korean skincare and is now on New Zealand shelves in serums and ampoules. A PDRN serum is used for the look of plumper, more hydrated, smoother skin. The visible part is hydration: a well made PDRN serum sits on a humectant base and skin looks fuller while you use it.
Using them together
There is no reason to use both topically. They are near enough the same idea. If you have had an injectable PN treatment, ask the clinic before rolling anything, and follow their timing rather than a product page.
Which to pick
For a serum, PDRN and PN are close enough that the rest of the formula and the price decide it. The word polynucleotide carries a clinic glow that a topical does not earn, so be wary of a serum that leans on it.
Questions people ask
Is a PN serum the same as PN injections?
No. Injections are a clinic procedure. A serum sits on the surface of the skin, whatever the label says.
PDRN or PN in a serum?
Treat them as the same ingredient family. Judge the serum by the rest of its ingredient list and how it feels.
Where Silka fits
Silka is a PDRN serum with a microneedle roller head on the bottle, made and shipped from New Zealand. The roller is the most practical way we know to put PDRN on every night: the head spreads the serum evenly across face and neck, nothing is left behind in your palm, and the whole routine takes about a minute, which is the part that makes a habit last.
