One's susceptibility to keloids and other types of aggressive scarring is largely determined by the genes. Ethnic patients--i.e., darker complexion is believed to be at increased risk. Fortunately, liposuction incisions are fairly small that they generally shrink and fade into imperceptible scars. The same is true for the injection sites (buttocks). Make sure that you consult with a board-certifified plastic surgeon who performs liposuction and BBL on a regular basis bec. he can identify potential risks and control if not minimize them. Possible modalities to promote favorable scarring or at least aid in quicker recovery include scar massage, scar creams, cortisone injection, silicone sheets, lasers, etc. Make sure that you share your specific concerns and all your medical history, including any history of aggressive scars, to your surgeon. Good luck and best wishes.
