my preference is to treat this type of scar with a fractionated CO2 laser system. I think this allows a certain depth of injury which helps improve these scars. Because you have ethnic skin ( pigment) we have to be more careful with your skin and often decrease our settings ( less aggressive). This means you will likely require more treatments to accomplish the same goal. Very deep acne scars are best treated with simple excision and closure( trading an acne scar for a better controlled scar).
