How it works
The Madeca derma mask III Brightening Formula is a 25ml sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Allantoin, Caffeine and Adenosine, 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. Centellian24 sells this Niacinamide sheet mask in Korea, and this is that version.
Key benefits
- Niacinamide, the active this sheet mask is built around
- Allantoin, Caffeine, Adenosine and Asiaticoside on the same list, actives
- Madecassic Acid and Asiatic Acid further down the same list
- Bisabolol and Saccharomyces Cerevisiae Extract further down the same list
- Niacinamide named sixth on the manufacturer list printed on this page
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 sixth.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it thirteenth on this sheet mask's list, beside Niacinamide.
Caffeineactive
Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin. The panel names it fourteenth on this sheet mask's list, beside 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 twentieth 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 twenty-third 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?
Allantoin, Caffeine and Adenosine. 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 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 rinsing, and keep sunscreen in the morning.
Worth knowing
- New to this formula: patch-test on the inner arm and wait a day before applying it to the face.
- Discontinue use if redness, itching, or irritation develops and rinse the area with water.

What professionals say
What professionals say
What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.

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.
