I wear sometimes foundation, powder, blush, eyeshadow, eyeliner and mascara. The problem is, 2 hours after I apply my make up I look greasy, stuff is smudged and it sometimes looks like im not even wearing powder or anything. I don't use the cheap stuff either. How can I fix this and what are the best kinds of make up to buy>

I have the same problem as you.. it's not the makeup that is the problem, it is your skin! Go to your dermatologist so they can recommend something to cut back on the oil that your skin produces.. it's usually a gel that you put on each night before bed and wash off in the morning.
