I can't emphasize enough the importance of not touching your fact at all durring the day, and getting lots of sleep.
Every time I go for 3 or more days with 9+ hours of sleep, my face clears up very nicely. Your body needs time to heal all the pimples.
Not touching your face is just as important. I was in the habit of touching my face all the time and I did not realize it. I would just rub my fingers over my face to see if I had any new pimples or anything. Well, I made a great effort to stop this habit, and whala....I cleared up some more.
I am also on retin-a, and anti-biotics at the moment.
Unfortunatly, I still have a greasy face which pisses me off a lot. I look terrible in pictures, my forehead looks all shinny - I hate it to no end.
