Good that you haven't done any procedures or used creams without proper advise. But it is very difficult to diagnose the type of pigmentation you have based on a photo. It could be post inflammatory hyperpigmentation or melasma or because of certain drugs etc. Only a close examination and one on one session with a dermatologist will help you. You will need prescription medicines that cause lightening of the patches... but these can be only given in person by a dermatologist. So go to one. You should benefit.
