Wash your face everyday! Mainly before going to bed
I wouldn't suggest washing it in the morning, because when you sleep the skin cells on your face are regenerating and making new ones, so you don't want to wash them all off!
Also, plenty of sleep is good. Like I said, while your sleeping your body regenerates new skin cells.
Try face washes, like a cleanser, and a scrub (but only use the scrub like twice a week)
If nothing works then try seeing a dermatologist
