I recommend this face mask!

My personal favorite mask pack recommendation, purchased with my own money, is Mediheal's Capsule 100 Bio Second Derm! This product works by absorbing sebum into the sheet if you leave it on for about 40 minutes, but I just use it until it dries out, haha. Usually about an hour? If you wet it with water after use, you can even see the oily sebum popping out! That's part of the fun, haha. Applying the included ampoule after use makes it even more moisturizing and great! There is plenty of product, so you can use it multiple times! It costs 5,000 won, so it's a product I stock up on whenever Olive Young has a sale, haha.
