The biggest difference was that my skin, overall, was far less oily than it normally is when I wake up. I normally wake up with very, very oily skin. It's obvious the moisture this mask puts in packs a punch. The big thing for me, which I did not expect to happen, is that a really painful, raised pimple flattened overnight. I don't know if that is just a coincidence, but I was pretty happy nonetheless.

My only real gripe with this mask is that the mask material is a little too thick for my liking. I prefer thinner mask material and the thicker material in this mask is probably the thickest of any mask I've ever worn. If you don't care about that kind of thing and your skin responds well to snail stuff, you'll probably love it. This mask is packaged in a square shape, and it's super teeny. The picture I've attached has an American quarter coin for comparison's sake.

I like this mask a lot, they're super moisturizing, and I love CosRx, but the price point will probably keep me from using it weekly. Overall it's a really wonderful mask, if you don't mind a thicker mask, and you respond well to snail products, you'll probably love it!
