For makeup, I recommend you go to a counter as well. I swear by Bobbi Brown makeup, her makeup is amazing and light years ahead of MAC. MAC also tends to be heavier, which may not help with your acne problem. ETA: also, it may be better if you just use concealer and a powder, which is what I do. You won't have to use the concealer all over, and the powder just gives you a finished look and helps blend.
