I have a lot of deep rolling acne scars on my cheeks and would like to consider subcision. I know that it will take multiple treatments and often needs to be combined with a laser. How will you know if your scars are responding to the treatment after a sessions? Once the swelling is gone a few days after, after a treatment, will that be the final results or will there be improvement months later? When during treatment do you see scars raised/filled in?
