Hi. Greetings. Most of the black or brown spots - or the crusts fall off withing a week and the black or brown marks fade away with time, faster with skin lightening creams for few weeks - under prescription by a qualified dermatologist near you. For the scars you'll need procedural treatment and they usually don't go away on their own. Warm regards, Dr Govind Suresh Mittal, Bengaluru.
