About 7 months ago I had several IPL treatments done on my face, chest and hands. Great results. Went back fore several more. Then I asked the laser tech to zap the freckles on my back and lower legs. 1 Hour after I left his office I was on fire, blistered and had these HUGE dark squares all over my back, 60 of them, the same on the lower legs. It was winter so no one could see. I now sit with all these white uneven squares. He said a chemical peel will help to even out the skin color. Help.
