Why discoloration after cosmelan peel and cosmelan 2 application? (Photo)

i had the cosmelan peel done 5 days ago. apparently i am peeling very fine but some part of my face is lighter than the rest. its like i am having white patches. i reacted to the hydra k factor of which an aqueous cream was substituted. i have reduced application of the cosmelan 2 to only places that are still peeling. i use my moisturizing sunscreen (spf50). what could be the cause of that? what do i do?
