Key actives
Niacinamide
Niacinamide sits at the very top on this ingredient list, and in Korean formulations it is reached for to work on the look of uneven tone and visibly enlarged pores with continued use.
Rosa Damascena Flower Water
Rosa Damascena Flower Water is named on this product's own ingredient list, sitting at the very top on it as one of the formula's declared ingredients.
1
1 is named on this product's own ingredient list, sitting in the front half on it as one of the formula's declared ingredients.
2-Hexanediol
2-Hexanediol is named on this product's own ingredient list, sitting in the front half on it as one of the formula's declared ingredients.
Acrylates/C10-30 Alkyl Acrylate Crosspolymer
Acrylates/C10-30 Alkyl Acrylate Crosspolymer is named on this product's own ingredient list, sitting mid-list on it as one of the formula's declared ingredients.
How to use
- Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
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 Niacinamide and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Niacinamide 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.

How it works
The Niacinamide 20% Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named second on its own ingredient list. It is the active this list is built around. How much of the Niacinamide 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 DERMA FACTORY sells in Korea, Niacinamide and all.
Worth knowing
- Patch test on the inner arm before applying to the face, as with any new skincare formula.
- Introduce a new active gradually into an existing routine rather than adding several new products at once.

Pretty much every step of a Korean skin care routine is going to have some component of hydration.
