Laser removal of scar tissue is typically performed by plastic surgeons, as the American Society of Plastic Surgeons explains. Laser treatment shows a 70 percent success rate when used to remove either keloids or hypertrophic scarring.
Modern non-ablative lasers are better able to work on deeper tissues and therefore provide more consistent results. These pulsed-dye lasers are most effective when used to treat scars that are less than one month old and when used on fair-skinned people. When used on darker skin, these lasers are more likely to reduce the redness of the skin without reducing the size of the keloid, as Patient points out. Laser treatments may need to be repeated on a five-to-six week schedule, according to the ASPS.
