Key actives
Ascorbic Acidantioxidant
Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. It is the entry this sheet mask is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named third on this sheet mask's list, alongside Ascorbic Acid.
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. It is named tenth on this sheet mask's list, alongside Ascorbic Acid.
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 thirteenth on this sheet mask's list, beside Ascorbic Acid.
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-sixth on this sheet mask's list, alongside Ascorbic Acid.
How to use
- Unfold onto a cleansed face, leave on for fifteen to twenty minutes, then remove and pat any remaining essence into the skin.
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 Ascorbic Acid and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Ascorbic Acid 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 Ascorbic Acid?
Niacinamide, Allantoin 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 Ascorbic Acid sits relative to them. Further down the same panel: Asiaticoside, Asiatic Acid and Madecassic Acid.

How it works
The RED BLEMISH Cool Vita C Clear Mask is a sheet mask, used after toner, in place of your serum step, in the evening. The antioxidant it is built around is Ascorbic Acid, named twenty-first on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid 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 Dr.G sells in Korea, Ascorbic Acid and all.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Ascorbic Acid on the list.
- Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Ascorbic Acid 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.
