How to treat acne

I no longer need to know how to treat acne now. Instead, i want to know how to get rid of acne marks. After applying Nixoderm onto my acne each night, they've somehow stopped appearing. So, Nixoderm really does work. But now, there are so many acne marks on both sides of my face. Kinda depressing looking at them each morning. I do not like the idea of covering them up with make-up. So, if you have a method on how to get rid of acne marks successfully, let me know. I want to give it a try. Thanks, horrrrr.
