I am not a doctor. However, my experience as a father of two girls (now grown) has given me some insight. Keeping your face clean of natural oils by washing frequently with an antibacterial soap helps as does drinking 6-8 glasses of water each day.  If this doesn't give you the results you hope for I would recommend a visit with a dermatologist.  They have a number of treatments that would be beneficial although not necessarily inexpensive. Hope this helps!
