How it works
The Madeca Derma Mask III Intensive Formula is a 10pads 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 Madecassic Acid, Adenosine and Asiaticoside, 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. This is the Original Korean Formula, the sheet mask Centellian24 sells in Korea, Niacinamide and all.
Key benefits
- Niacinamide, the active this sheet mask is built around
- Madecassic Acid, Adenosine, Asiaticoside and Asiatic Acid on the same list, actives
- Allantoin and Caffeine further down the same list
- rh-Oligopeptide-1 and Artemisia Absinthium Extract further down the same list
- Niacinamide named third on the manufacturer list printed on this page
- Sourced for the Korean market, not a US-shelf reformulation of this sheet mask
Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this sheet mask's own ingredient list it is named third.
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 ninth on this sheet mask's list, alongside Niacinamide.
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 eighteenth 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 nineteenth on this sheet mask's list, beside 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. The panel names it twentieth 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.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Niacinamide and all. We match this sheet mask 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?
Madecassic Acid, Adenosine and Asiaticoside. 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: Asiatic Acid, Allantoin and Caffeine.

How to use
- Use it in the evening after toner, in place of your serum step.
- Line the sheet up at the eyes first, then press it flat from the middle outwards.
- Leave it fifteen to twenty minutes and take it off while it is still damp.
- Two or three times a week. Press in what is left rather than putting a heavy cream over the top.
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.
