Can Skin Discolored by IPL Treatment Be Corrected?

After several chemical peels done on my back, there was an obvious big patch of uneven brown color on my skin. I was advised to go for IPL treatment to get rid of the discoloration. I got my first IPL treatment done one and a half week ago. After my IPL treatment, the skin on my back was left dark red, swollen, and itchy. The itchness and swollen parts were gone after the first week.

During the start of the 2nd week, my skin has turned dark brown in color. Majority of my skin were dry and looked burnt and crusty. They began to peel off. But I realized that the parts which have been peeled off appear light brown in color while the rest werent peeling at all. Now, I'm very worried that the uneven skin color would remain or in fact, get worst as compared to before the IPL treatment. Is this the final result? Can this discoloration be corrected?
