I wanted to ask your professional opinions on the CICU CO2 Deep Fractional Laser for acne scarring?

I have deep acne scars; mostly rolling and box car ones.. I actually got a dermabrasion about 9 years ago but there were still deep scars..now I'm older and it looks more obvious. My derma suggested that we do a CICU CO2 deep fractional laser to improve it. I wanted to ask if there will be any improvement to my skin at all, considering I had a dermabrasion already.. will it look better if I get the laser? What are the chances of the CICU CO2 Deep fractional laser do any improvement?
