Cosmetics make me Break Out

I thought I loved the new products I bought. However, my skin looks like a great big pizza. Filled with flaws, spots, and pimples that just can't be covered up. How am I supposed to go to school looking like this?! I am looking into purchasing mineral makeup. From what I've heard, it works pretty well. I also am going to need an awesome makeup primer for my skin. Clearness, here I come!
