Open Question: what should I expect when using differin .3 and solodyn 45 mg?

I went to a dermatologist last Saturday of my acne, it is mainly too small, looks like a scar, but not the red and black lumps. He gave me these two products, and told me that if my face Duff stimulus only for the first time to use it every night. It does not have it every night so I. I think I just started cleaning Duff phase. Spots, where even worse, I got some new problems. How long before the start of this stage, the last I am becoming more clear? At the same time, how long until I really understand all of it? Do not leave a scar? How can I expect one of them or both? Thanks!
