PDRN vs Retinol: 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 retinol (a vitamin A derivative) beside PDRN, plainly.
| PDRN | Retinol | |
|---|---|---|
| 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 best known of the vitamin A family in over the counter skincare. It is the ingredient people think of first for the look of ageing skin, and the one with the most opinions attached to it. |
| 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. | Used for the look of smoother, more even skin over months rather than weeks. Early on it commonly makes skin look flaky and feel dry or tight, which is why so many people start it and stop. |
| How it feels | Watery, light, settles in about a minute. It is the kind of serum that suits a roller. | Usually a cream or an oil rather than a water. It can sting on damp skin and it does not like being layered with much else at first. |
| When to use it | Night, on clean dry skin, most nights. | Night only, and rarely every night to begin with. It needs sunscreen the next morning without exception. |
What retinol is
The best known of the vitamin A family in over the counter skincare. It is the ingredient people think of first for the look of ageing skin, and the one with the most opinions attached to it.
What retinol does for the look of skin
Used for the look of smoother, more even skin over months rather than weeks. Early on it commonly makes skin look flaky and feel dry or tight, which is why so many people start it and stop.
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
Not on the same night while you are getting used to retinol. Alternate: retinol two or three nights, the PDRN serum on the others. Once your skin has settled into retinol, a PDRN serum on the nights between is the easy way to keep skin looking hydrated through the dry patch.
Which to pick
Retinol suits people who want the long game and can tolerate the adjustment. PDRN suits people who want skin to look plumper and softer without a rough first month, and anyone whose skin already feels dry or reactive.
Questions people ask
Is PDRN a gentler alternative to retinol?
It is gentler in the sense that it does not usually make skin look flaky or feel tight. It is not the same ingredient and it is not doing the same thing. Think of it as the hydration side of the same routine.
Can I roll a PDRN serum on the night after retinol?
Yes, and it is a sensible pattern. Keep the roll light and skip it on any night your skin looks pink or feels sore.
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.
