Greetings.. You'll need skin lightening creams for a specified duration to reduce the marks , and this could also be dealt with chemical peeling. Also you must use a sunscreen to prevent darkening of the spots or pigmentation. For scars, creams may not work n you may need procedures like microneedling, microneedling rf, fractional lasers, prp or subscision or a combination of these. Send in snaps of your lesions/pigmentation/ marks on follow up chat if you need further assistance. Or see a dermatologist near you and discuss the same with him. Hope this helps. Warm regards.
