Co2 Treatment to Remove Fibromas

i have had co2 laser operarions done to my torso before and these always eventually leave a small white scar. i have had quite a lot of fibromas removed from my face, i am worried that the redness is not going to fade like the other areas have. they have all healed well but are still red.

how long should it take for these areas where the fibroma has been removed to fade from red? This is not resurfacing there has been a deeper treatment done.
