Would acne scar go away on its own or should I do something about it?

I am currently using acne products by doctor related to acne breakout. I have been using it for months and it really does work and I have less breakout now. The products that I am using are Differin (adapalence) cream, minocycline, and clindamycin phosphate. My face does improve and has less breakout, however, acne scar from the past become more visible. What should I do? Would it go away or should I go to the doctor again because I don't want the scar in my face forever. Help please.
