Hi Vrinda , thanks for posting to us I understand your concern about scars For the reduction of pigmented scars you may do as follows: Use a non comedogenic sunscreen during the day A glycolic face wash like melawash twice a day You may use demelan cream (contains glycolic acid, arbutin and kojic acid ) which will help in reduction of pigmentation and scars But use this under dermatological supervision as it may cause some redness and dryness which can be taken care of with moisturisers and sunscreen in addition to avoidance of sun exposure as much as possible If you dont have active acne lesions, you may undergo procedures like glycolic peels , microdermabrasion, dermaroller , fractional laser . Consult a dermatologist for the type of scars and best suitable treatment option for you Hope this solves your query All the best
