Hi. Greetings. Your history is not very clear. Probably you have had a fixed drug eruption in the past and now have post inflammatory hyperpigmentation. Kindly send your pictures on private follow up chat or see a dermatologist near you. It may not be possible to fully remove such pigmentation but can be reduced to variable extent. Hope this helps. Warm regards..
