Dermabrasion After Fractional Laser for Acne Scars?

Can Dermabrasion help improve my acne scars more after a Fractional laser treatment? I had cystic acne before, so I was under Roaccutane afterwhich, TCA peels were done since Dermabrasion and the like were contradictory. After a number of years, skin needling was done, which softened the little tiny elevated scars and made the depressed scars less deep. Now I just had my third Fractional laser resurfacing done. So far, the scars look like they almost blend with my skin but with borders. My question is, would a Dermabrasion help to smoothen or blend these shallow scars after Fractional laser resurfacing?
