How it works
The Niacinamide 10 Serum is a 40ml 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. The same list carries Tranexamic Acid, Asiaticoside and Madecassic Acid, so the active is not the only thing on it worth naming. 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 JUMISO sells in Korea, Niacinamide and all.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is the entry this serum is named after, and the list carries it.
Tranexamic Acidactive
Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired. It is named fourteenth on this serum's list, alongside Niacinamide.
Asiaticosideactive
Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised. It is named twenty-eighth on this serum's list, alongside Niacinamide.
Madecassic Acidactive
Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula. It is named thirtieth on this serum's list, alongside Niacinamide.
Asiatic Acidactive
Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers. It is named thirty-first on this serum's list, alongside Niacinamide.
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.
What else is on the list besides Niacinamide?
Tranexamic Acid, Asiaticoside and Madecassic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Asiatic Acid, Zinc PCA and Allantoin.

How to use
- Apply it on damp skin straight after toner, which is when a light fluid travels the furthest.
- Two pumps cover a face, pressed in with flat palms so nothing is dragged across the cheeks.
- Follow with a cream once the surface has turned tacky, which usually takes under a minute.
- Avoid layering three treatment serums at once, because a crowded treatment slot is where pilling and stinging start.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.

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.
