Abstract

An electromagnetic energy system adapted to reduce scar formation associated with a skin wound includes a memory, an electromagnetic energy source, an optical energy conduit, a handpiece, and a controller. The memory includes predetermined beam parameter information. The electromagnetic energy source is adapted to generate an electromagnetic energy beam having at least one beam parameter corresponding to the predetermined beam parameter information. The electromagnetic energy beam having the at least one beam parameter is adapted to reduce scar formation associated with a skin wound. The optical energy conduit has a proximal and a distal end, and is coupled to the electromagnetic energy source at the proximal end. The handpiece is coupled to the distal end of the optical energy conduit. The controller is adapted to activate the electromagnetic energy source to deliver to a treatment area near the skin wound. The electromagnetic energy beam has the at least one beam parameter corresponding to the predetermined beam parameter information.
