If you do think about trying a mineral foundation, I strongly suggest getting some samples... and a great company to do that with is L.A. Minerals. You can find them online at laminerals.com You can get several different samples to try to find the right shade and they also have three different formulas--a light coverage, a medium coverage, and a heavier coverage which is great for people with breakouts as it is easier to hid acne as well as treat it at the same time.
They have a great online store and extremely reasonable prices. I've been using their foundation, blush and some eyeshadows now for several years and am EXTREMELY happy. My daughter is 16 and has acne breakouts and loves it as well. Even if you have a dry spot during the winter months, it's easy to blend in with a moisturizers to get a tinted coverage for those areas.
Good luck, and let me know if you decide to give them a try!
