Clear and brilliant laser burnt my face

I had very few pigmentation spots when I decided to try the clear and brilliant laser as I was advised it is the only laser for women of color that is safe, the results were great after three sessions and then on forth season I believe the technician went full throttle and ended up burning my skin and subsequently I now have hyperpigmentation- I bought all the recommended products they sold which are skin ceuticals and that has not helped - I have always worn sun block and avoided the sun - from having a few spots I now have two huge dark patches on either side of my face which are awful, I had a full course of the VI peel with a great doctor but that did not help either - I am so disappointed!
