Need a few pointers to improve my apperance?

Ok, well I will state nothing but the truth. My biggest issue with my apperance right now is my face. I just can't get rid of damn dry skin, and it drives me crazy. I try washing my face all of the time, and I don't try to overdo it either, but dry skin still shows up. Before all of this stuff showed up, my apperance was viewed very highly among most women, but now I don't even like how I look. It makes me look unclean, which is far from the truth since I brush my teeth 3X a day, shower 2 times a day, wash my face twice a day, wash my hair twice a day, and always smell nice. I also want to know if sleeping helps you look better? Lately, I've struggled to get any sleep at all. I'd say..I go to bed around 3-4 AM each night, then wake up around 11-12. I hate living that way, and it isn't going to help me with college around the corner, so I need to change that fast. I was wondering if the way you sleep affects your apperance a lot also? Thanks to those who help.
