I was intrigued by the concept of the bubbles, so I decided to give this a try. It foams up a LOT more quickly than I expected- some bubbles started appearing even before I'd finished covering my entire face with the mask. The bubbles don't slide off my face, and I like how cleansing it feels on my skin. I didn't notice too much of a difference with blackheads, but my skin felt cleaner with no irritations. Overall I think it's worth a try, especially considering how fair the price is!
