PDRN vs Niacinamide: 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 niacinamide (vitamin B3) beside PDRN, plainly.
| PDRN | Niacinamide | |
|---|---|---|
| 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. | A form of vitamin B3 that has been in skincare for decades. It is water soluble, sits happily in light serums and moisturisers, and is one of the few actives almost every skin type gets on with. |
| 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. | People reach for it for the look of a more even surface: skin that appears less blotchy, with pores that look a little tighter and a finish that reads smoother under makeup. |
| How it feels | Watery, light, settles in about a minute. It is the kind of serum that suits a roller. | Watery to lightly milky. It settles fast and leaves nothing behind, which is why it turns up in so many daytime products. |
| When to use it | Night, on clean dry skin, most nights. | Morning or night, most days. It is one of the easiest actives to use every day without the skin noticing. |
What niacinamide is
A form of vitamin B3 that has been in skincare for decades. It is water soluble, sits happily in light serums and moisturisers, and is one of the few actives almost every skin type gets on with.
What niacinamide does for the look of skin
People reach for it for the look of a more even surface: skin that appears less blotchy, with pores that look a little tighter and a finish that reads smoother under makeup.
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
They layer without fuss. Niacinamide is usually the thinner of the two, so it goes on first, then the PDRN serum, then a moisturiser if you use one. Many rollers hold a PDRN serum that already has niacinamide in it, which settles the question.
Which to pick
Niacinamide is the pick for skin that looks uneven or blotchy in tone. PDRN is the pick for skin that looks flat, dry and less full than it did. Plenty of people want both, and there is no reason not to.
Questions people ask
Can I use niacinamide and PDRN together?
Yes. They do different jobs for the look of skin and neither interferes with the other. Thinnest first, then give each a minute.
Does niacinamide make skin look plumper?
Not really. It is about evenness and finish. Plumped-looking skin is the hydration side, which is where PDRN and hyaluronic acid sit.
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.
