This is tough and I feel your pain. I had Cystic acne all thought high school and college and I look back at pictures and think omg the make up looks caked on! And it was because at that time there really was no suce thing as Mineral Make Up and that is really going to be the key here. First you want to avoid powders opt for a liquid mineral foundation...my favorite is Mineral Secrets Liquid Mineral Powder Based and it can be found at www.MineralSecrets.com. The Liquid Foundation Powder delivers all the benefits of mineral makeup powders in an easy-to-use hypoallergenic liquid powder. It is the best product I have ever used and I have been an Esthetician and Make up Artist for almost 4 years. If you feel you need a little extra coverage Mineral Secrets also offers a Camoufleur Concealer (ivory is the best color) that is better than any concealer I have ever tried! It is made with plyable molecules that wont rub off, its molds to your skin and is water and crease resistant. Trust me you want to look into this. Also your not paying for the "Bare Minerals or Bare Essentials" name you are getting an equally superior product without the retail mark up!
