Should I get Bare Minerals????

hi ok im 14 and in 8th grade and I love makeup. I wear foundation to school (liquid) but at the end of the day my face looks gross and like some pleaces on my face are darker then others from the foundation. I use pressed powder and even blotting sheets and primers but nothing seems to help my OILY skin. Anyway... I have tried so many foundations and have had the same problem. So i was wonder if Bare minerals is good for oily skin? I know a couple girls who use it and they like it.
