How it works
The 8 Hyaluronic Acid Catechin Cool Slim Mask is a 1ea sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Methyl Diisopropyl Propionamide, named seventeenth on its own ingredient list. The same list carries Caffeine, Coptis Japonica Root Extract and Theobroma Cacao (Cocoa) Extract, so the active is not the only thing on it worth naming. How much of the Methyl Diisopropyl Propionamide stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. Anua sells this Methyl Diisopropyl Propionamide sheet mask in Korea, and this is that version.

Key actives
Methyl Diisopropyl Propionamideactive
A synthetic cooling agent that gives the cool feeling of menthol without the mint smell. It is used where a formula wants the sensation but not the scent. On this sheet mask's own ingredient list it is named seventeenth.
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 twenty-first on this sheet mask's list, alongside Methyl Diisopropyl Propionamide.
Coptis Japonica Root Extractplant extract
Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin. The panel names it sixteenth on this sheet mask's list, beside Methyl Diisopropyl Propionamide.
Theobroma Cacao (Cocoa) Extractplant extract
Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint. The panel names it twenty-fifth on this sheet mask's list, beside Methyl Diisopropyl Propionamide.
Trehalosehumectant
Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight. The panel names it fifth on this sheet mask's list, beside Methyl Diisopropyl Propionamide.

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 Methyl Diisopropyl Propionamide and not three changes at once.
What else is on the list besides Methyl Diisopropyl Propionamide?
Caffeine, Coptis Japonica Root Extract and Theobroma Cacao (Cocoa) Extract. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Methyl Diisopropyl Propionamide sits relative to them. Further down the same panel: Trehalose, Inositol and Honey Extract.

How to use
- Use the 8 Hyaluronic Acid Catechin Cool Slim Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test on the inner arm before applying to the face, as with any new skincare formula.
- Introduce a new active gradually into an existing routine rather than adding several new products at once.

It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.
