Hi. I Treated Warts On My Face With Raw Garlic.

Hi. I treated warts on my face with raw garlic. I put crushed garlic under a band aid for almost 2 hours. And it burnt my skin. it is already 3 weeks since I put garlic. now, my skin wwas fully recovered and healed with no scar. but I left a hyperpigmentation. what will I need to do to completely remove the hyperpigmented burn mark? Is there any chance that I can fully recover my skin from its original color? thank you and Godbless.
