If your scarring is truly superficial, than the Fraxel laser, done in a top notch center, may be a good choice for you.  Without seeing you, it's not possible to say for sure.   Find a center and a Dermatologist with a lot of experience, and one that treats african american skin frequently.  Make sure the doctor is on site full time. Don't  use a carbon dioxide laser even if it's fractionated because, even with the newer technology, there isn't  enough safety data yet on african american skin.  Good luck!  Dr. I
