Key actives
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. On this sheet mask's own ingredient list it is named fifteenth.
Acetyl Glucosamineactive
Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide. The panel names it twenty-sixth on this sheet mask's list, beside Allantoin.
Succinic Acidactive
Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here. The panel names it thirtieth on this sheet mask's list, beside Allantoin.
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. It is named thirty-fifth on this sheet mask's list, alongside Allantoin.
Saccharomyces Ferment Filtrateferment
Saccharomyces Ferment Filtrate is a brewers yeast ferment filtered clear. It supplies amino acids, B vitamins and sugars, and it is one of the ferments the Korean essence category was built on. It is named seventh on this sheet mask's list, alongside Allantoin.
How to use
- After toner, once or twice a week. Unfold over the face, leave on for 15 to 20 minutes, then remove and pat in any remaining essence.
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 Allantoin and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Allantoin 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 Allantoin?
Acetyl Glucosamine, Succinic Acid and Caffeine. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Saccharomyces Ferment Filtrate, Ceramide NP and Sodium Heparin.

How it works
The Nosca9 Trouble Serum Mask Sheet is a sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Allantoin, named fifteenth on its own ingredient list. The same list carries Acetyl Glucosamine, Succinic Acid and Caffeine, so the active is not the only thing on it worth naming. How much of the Allantoin 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 Fation sells in Korea, Allantoin and all.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Allantoin on the list.
- Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Allantoin rather than to three changes at once.

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.
