You have undergone so many types of cosmetic procedures including chemical peels
and lasers that further such sessions may even damage you skin including burns and post burn hyperpigmentation
, as you desire to get better resul may compell the treating doctor to use higher energy delivery settings in such session which may be counterproductive.
I suggest to you that a certain degree of realistic approach is better in you case as your skin coloration is already fixed. Better use natural products like cucumber piece and termeric paste at night and a camoflouge shade during day time along with sunglasses.
