How can I correct permanent discoloration/redness post-dermabrasion?

I had a mole in the center of my nose that I got removed many years ago but it unfortunately left a divot that made me self conscious as it was worse looking than the mole. In Feb 2022 I saw a dermatologist who did Dermabrasion procedure on me. I still have a divot but now it’s actually darker and the surrounding area is pink/red. I got 3 micro needling treatments which helped a little. The redness is really upsetting. What else can I do to correct this? Lasers?
