Scar Revision Surgery

 I have a scar on my cheek, which was caused by severe acne. It is quite large, and some say that it is cute as it is on my cheek. But I don't like that and want it to be removed immediately. My friend is a doctor and she told that a scar revision surgery ( http://www.solomonfacialplasti...ery/scar-revisions.php ) could easily remove the scars. I have a dark complexion. Can I undergo a laser treatment if I have dark skin? Does it cause my acne to worsen?
