Key actives
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. It is the entry this serum is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fifth on this serum's list, alongside Sodium DNA.
Retinalactive
Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque. The panel names it twentieth on this serum's list, beside Sodium DNA.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named twenty-second on this serum's list, alongside Sodium DNA.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it twenty-sixth on this serum's list, beside Sodium DNA.
How to use
- Use it after toner or essence and before moisturizer, AM and/or PM. Dispense two to three drops into the palm and press over the face and neck, letting it absorb fully before layering.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Sodium DNA and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Sodium DNA and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Sodium DNA?
Niacinamide, Retinal and Dipotassium Glycyrrhizate. The order they are printed in on this serum's panel is the order on the box, so you can see where Sodium DNA sits relative to them. Further down the same panel: Adenosine, Tripeptide-1 and Acetyl Hexapeptide-8.

How it works
The Rose PDRN Firming Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Sodium DNA, named thirty-fifth on its own ingredient list. The same list carries Niacinamide, Retinal and Dipotassium Glycyrrhizate, so the active is not the only thing on it worth naming. How much of the Sodium DNA stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum Haruharu sells in Korea, Sodium DNA and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Sodium DNA on the list.
- Retinal is on this list, so keep this serum to the evening and build the nights up slowly rather than starting nightly.

Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
