Talk to Dermatologist on Acne And Scars Problem

I have been suffering from acne and scars for a long time. I went to a doctor but it didn't improve so I left those medicines after one and half year treatment. Then I searched on internet I came to know that I would have to take proper treatment. Then I started to take medicine again in September according to doc prescription. My course is about to complete but my acne and scars problem is not improving. I am going to married within 2 to 3 month therefore I am so much worried. I want clear skin.
