Lately I've been using "Wonder finish" from maybelline as a foundation/concealer, and though it says it won't clog pores, my skin has been getting steadily worse in the parts I use it the heaviest on -my nose and forehead- but I was wondering if it was better to use a powder concealer, and why it would be doing this to me (Poor face of mine. It was almost completely clear.), it says it's oil free, and my skin needs that. Very oily and sweaty. Almost paint-like in the consistency of the oil.

I don't know if it's possible, but if any of you can, would you tell me exactly why it's doing this, or if it's just the heat, if you've used it and what reaction you had, and/or a better concealer or foundation for my skin?

Lots of love and thanks.
