Dark spots and MIXTO laser
MIXTO laser is effective to help break up pigment within the skin but it is important for patients with significant pigment issues to be on a strong program of anti-pigment products before, during and after treatment. You should expect your pigment issues to be improved but likely not eliminated. We recently reported (publication in process) on successful MIXTO treatment of a patient with an inherited condition called ichthyosis with similar pigmentation issues to yours.
Mixto fractional laser is safer than traditional Co2 laser for people with darker skin complexion. What you have is moderate to severe post inflammatory hyper-pigmentation (PIH). The good news is that it will eventually go away. I have performed thousands of Mixto Co2 laser treatments for the past 7 years and never seen this reaction not go away.
I routinely prep my patients with sensitive skin before laser treatment with Bleaching cream and Retin A.
Your dermatologist should be able to give you Retin A, Bleaching cream and maybe even light Glycolic peels and Kojic acid to remove the discoloration.
I would suggest refraining from Co2 laser. Look into TCA peels as an alternative option.
