I had severe acne for 4 years, in the early 90's.
I've since been focusing on all-around skin care, and I'm proud to say that my scars aren't very noticeable anymore!
I wash my face morning and night with a gentle cleanser (you might want to use one with salicylic acid in it to prevent further breakouts if you're worried). I always moisturize.
And very importantly, EXFOLIATE, EXFOLIATE, EXFOLIATE!
I use mud masks 2-3 times a week (different ones) - it doesn't matter if you're male or female. Masks deep-clean the skin, help keep it healthy, and exfoliate the dead skin. The only way to get to the good skin underneath is to get rid of the dead skin.
(I also use a home dermabrasion system).
And of course, drink a lot of water.
