Sheer Cover Mineral Makeup Review

I have been acne-ridden for more than half my life (I'm 34). I wanted to try something that didn't clog my pores. The infomercials made the ladies look like movie stars, and they had wonderful coverage. When I first apply the makeup, I look great. After about 30 minutes, my oil totally messes it up. After about an hour, it seems I have nothing left on my face. I am hoping to try a different brand and really want it to work. I believe in the mineral makeup- my face has cleared up almost the way. I just need more and longer coverage for my damaged skin.
