What age does adolescent acne USUALLY go away in males? Both parents are acne free. I'm 21 with mild-moderate acne. Is there a change I can outgrow it?

Yes. YOu should slowly out grow it. IF there is no strong genetic pattern, although there are no known such factors. Good facial skin care, avoiding infections, good hydration, nonhandling of facial skin and some topical benzyl peroxide preps help.
