I recommend Mediheal mask packs.

I also found out about this mask pack by chance.

I really like it, so I recommend it! You are supposed to leave this on for about 30-40 minutes, but I leave it on for about an hour until it dries. Once it's dry, I take it off and soak it in water, and I can see the oil coming out of my pores.

You can see everything! I think that makes it fun, too! And I found it really great to apply a generous amount of the ampoule to my face after using everything up! It's a product I always stock up on whenever Olive Young is on sale!
