See a dermatologist: if you have postinflammatory hyperpigmentation, and you have darker skin pigment, this may be more noticeable. So you need to go very carefully and being able to reverse this. Time is on your hand, however you may need other interventions or lotions that may require a prescription. You need to speak with a dermatologist first. Do not try to self treat this, or it may darken further.
