Hi You seem to be having both pigmentation as well as depressed scars. You need a good home care regime for your skin like salicylic acid face wash twice a day, frequent application of sunscreen as well as topical retinoids and skin lightening creams. In addition to prevent further break outs you need to be evaluated snd started on oral retinol tablets as well. When further break outs have stopped elect for chemical peels for the skin marks and fractional laser resurfacing for the scars. Please contact a dermatologist who offers FDA approved laser technology in your city
