I had slight darkness around the mouth so I used a glycolic acid face wash(5%)for more than a week.I also experienced peeling around the mouth twice but after that the area has become darker than before.I consulted a dermatologist who has suggested me ONABET SD LOTION for the affected area but when I googled about the lotion I found out that it is used for inflammation(which I have none).Can you tell me whether I should use this or not.
