Tretinoin-acid For Acne scars after laser-resurfacing?

I am finally done with my Isotretinoin course, although it left a lot of acne scars. I got a laster treatment, that reduced the scars by 15%, however there are still some left (rolling scars) mainly. My dermatologist provided me Tretinoin-acid (0.025) for this. Will this help me get rid of my last rolling scars? Also, will it in any case worsen my scarring? Because after fighting so hard against the scars, they are finally about to disappear, and I really don't want to mess it up.
