One fundamental rule that helped me through puberty and that works for me ever since is to NEVER touch my face during the day unless I have washed my hands first. The amount of dirt and crap you pick up from tables, door handles and other objects is unbelievable. Always carry some clean tissue so that if you have an itch or something you can rub the clean tissue over it instead. This is for the face only of course. You would do good to wash your face with oxyten during every couple of hours with hot water. It works better overall than using only twice a day
