How it works
The Niacinamide TXA Dark Spot Serum Mask is a 1ea sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Niacinamide, named third on its own ingredient list. The same list carries Tranexamic Acid, Arbutin and Alpha-Arbutin, 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 sheet mask format rather than by the list alone. Anua sells this Niacinamide sheet mask in Korea, and this is that version.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is the entry this sheet mask 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. The panel names it fourth on this sheet mask's list, beside Niacinamide.
Arbutinactive
Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two. It is named eighth on this sheet mask's list, alongside Niacinamide.
Alpha-Arbutinactive
Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH. The panel names it tenth on this sheet mask's list, beside 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. The panel names it forty-first on this sheet mask's list, beside Niacinamide.

Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. 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.
What else is on the list besides Niacinamide?
Tranexamic Acid, Arbutin and Alpha-Arbutin. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Asiaticoside, Madecassic Acid and Asiatic Acid.

How to use
- Use the Niacinamide TXA Dark Spot Serum Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Introduce this sheet mask 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.
