...last long and cover a lot.
i have OILY skin, adult acne, and i want to use powder foudation. i need to know what is good for acne that i can go buy at the store. like tonight.

I have the same overy oily and acne prone skin and I finally found my perfect foundation. Its not minerals though. Its Chanel Double Perfection. it lasts all day and doesnt affect the acne. its expensive, about 50 bucks a compact but it last a long time. i love it

I use bare minerals
You should try it.
Some peoples skin reacts different to it though so thats why when I went to the make up counter they made me a make-over using their products and I loved it!
However, bareminerals isn't always close so you have to order it and see how you like it.

Good Luck

OMG NOT BARE MINERALS! use the mabeline dream matte mousse! it works really well and it has spf and it moisturizes your skin and its oil free. it wont clog pores either. do you want powdery wich can fall off and look gross or smooth?
