If it is raised you could consider Laser Resurfacing but with dark skinned individuals the risk of complications is little more. I would excise your scar and close it possibly in a geometric fashion to break up a noticeable line and then consider resurfacing in less aggressive means. You can consider fractional resurfacing to decrease the complications. This can be done and with the surgeon he will hold your hand through the whole process and do his/ her best to make sure that you are happy.
Laser resurfacing, chemical peels, and dermabrasion all do essentially the same thing, they take off the top layers of the skin removing pigment, wrinkles, scars, tighten pores, and tighten skin. The hair follicles are where the source of skin cells come from and these cells eventually resurface the skin and rejuvenate the skin. When the scars are removed the cells from the hair follicle, deep within, resurfaces the scar with new skin making the scar appear better. Sometimes certain scars need other techniques such as excision and reclosure and other subcision techniques to more fully improve the appearance of the scars.
