My dad had pimples untill he got married, i am 16 and i too am sufering from acne? i want to ask u when will these acnes stop in my case?

No predicting: I was able to stop taking medication for my acne when i was 50. If as you seem to report you are on Clindamycin monotherapy for acne, you're making a mistake and should add topical benzoyl peroxide or a retinoic acid derivative. If it's not sufficient (and i see you already have scarring), consider isotretinoin. It's not for the faint-hearted but it might be the best thing for you.
