I have pimples that never go away unless i am on the yaz. what else am i use ?

Acne on oral bcp's: If by "go away" you mean when you are actually taking the "active" pills of "Yaz", and not just when you take the "inactive " pills (placebos), it is expected that a low dose oral contraceptive pill if taken punctually ( the same hour each evening) will improve your complexion. There is no need to take another kind of bcp, but you can take only the active pills for 2-3 months, without a break.
