PDRN vs Squalane: 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 squalane (plant derived squalane, usually from olives or sugarcane) beside PDRN, plainly.
| PDRN | Squalane | |
|---|---|---|
| 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 light oil that closely resembles one skin makes itself. It is the oil for people who think they hate oils. |
| 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. | Skin looks soft and lit from within rather than shiny. It is a finishing step, not a fixer. |
| How it feels | Watery, light, settles in about a minute. It is the kind of serum that suits a roller. | Thin, dry to the touch within a minute, no smell. It sits over anything. |
| When to use it | Night, on clean dry skin, most nights. | Night as the last step, or morning under sunscreen for dry skin. |
What squalane is
A light oil that closely resembles one skin makes itself. It is the oil for people who think they hate oils.
What squalane does for the look of skin
Skin looks soft and lit from within rather than shiny. It is a finishing step, not a fixer.
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
The classic order: PDRN serum first, a few drops of squalane after. The oil keeps the water based serum from evaporating off dry skin. Never the other way round; oil first blocks the serum.
Which to pick
Squalane is not really an alternative to PDRN, it is the layer over it. If you can only have one and your skin is dry and flaky, squalane. If your skin is comfortable but looks flat, PDRN.
Questions people ask
Can I put squalane through the roller?
No. Oils do not roll well and they stop the serum doing its job. Roll the serum, then press oil on with fingertips.
Squalane or a moisturiser over PDRN?
Either. Squalane for a lighter finish, a cream for drier skin or winter.
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.
