I had more dark pigmentation after my glycolic peel in the perioral area. Please do help me. (photos)

I had pigmentation on my upper lip and below the lower lip. My doctor did glycolic peel and my skin was inflamed and i was prescribed with mometasone furoate. Later the dead skin got peeled off but left with dark patches alk around the mouth giving an appearance like a moustache. Then i was prescribed with kojivit. I have been using this since a week but there was no change. Its really sucking me cant go out like this. Feeling very sad n awkward. Please give me any suggestion
