White spots on my body after a chemical liquid burned my hand. Did a chemical peel on my face. Can I do the rest of my body?

I have some white spots started to appear after i got burned with a strong chemical liquid on my hand. a dermatologist said its vitiligo, i tried the corticosteroids & special diets but the spots reappeared if not in the same place, in different places, then i decided to use monobenzone and chemical peeling, and the results on my face were perfect, but now i have different colours in my body coz i am dark skin & my face is lighter. i don't know if i can peel the whole body the same way Regards
