## How it works

The Vitamin C Expert 40% Mask Concentrate is a 15g sheet mask, used after toner, in place of your serum step, in the evening. The antioxidant it is built around is Ascorbic Acid, named first on its own ingredient list. The same list carries Nicotinamide Mononucleotide, Thymol Trimethoxycinnamate and Resveratrol, 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 IOPE sells in Korea, Ascorbic Acid and all.

## How to use

1. After cleansing, 1 to 2 times a week.
2. Apply as directed, avoiding the eye area.
3. Follow the product's own rinse-off or leave-on timing.

## FAQ

### 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?

Nicotinamide Mononucleotide, Thymol Trimethoxycinnamate and Resveratrol. 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: Glycine Max (Soybean) Polypeptide, Hydrogenated Polyisobutene and Cetyl Ethylhexanoate.
