Post Inflammatory Hyperpigmentation From Lasers -- Skin Lightening, Light Peels, microsecond YAG
I suggest seeing an expert in lasers and pigmentation, a cosmetic dermatologist who treats a lot of dark skinned patients who have these issues naturally. You will need a combiantion approach and different laser hair removal device like Aerolase or the like. Best, Dr. Emer.
Do chemical peel with vi peel to whole face-safe and effective on any color of skin.You could then use bleaching cream if necessary for residual color .You could also be treated by Sciton Halo or Picosure photorejuevenation for melasma
