This might sound gross to some people, but if you use a non-comedogenic creamy-type anti-perspirant on your face before your makeup, it solves the problem entirely! I learned this trick when I used to work in a very hot environment but I still needed to look nice. My co-workers taught me. I just use the Secret twist-up kind. It won't clog your pores either (I'm very cautious about that). I'll add that I have extremely sensitive skin and this never caused a problem for me.
That said, yes, I do wear a normal amount of makeup every day at Disney (chapstick, concealer/ foundation, eyeshadow, blush, eyeliner and mascara.)
I hate looking like crap in pictures and with the anti-perspirant trick, I've never had a problem keeping it on!
