I have really oily skin and live in humidity hell (Florida), so when I want to feel "fresh", I use this Mint Julep mask. It's really cheap which = bonus, and it actually works. I don't suffer from acne, but everytime I've had a problem or two, the mask also takes care of it. I'm usually a product snob when it comes to my face, but I swear by this stuff.

The only downside is that it's green so you look like an alien for about an hour but it usually leaves my face feeling smooth, so it's worth it.

You can find it at any Walmart or supermarket, or you can go here.
