Scars may occur for many different reasons. These include infections, surgery, injuries, or inflammation of tissue. A scar is the body's natural way of healing and replacing lost or damaged skin. Scars may appear anywhere on the body. The makeup of a scar may vary. The scar may be flat, lumpy, sunken, colored, painful, or itchy. Scars may be treated with a variety of different lasers. This depends on the underlying cause of the scar. Lasers may be used to smooth a scar, remove the abnormal color of a scar, or flatten a scar. Most laser therapy for scars is done along with other treatments such as steroid injections, special dressings, and bandages. Multiple treatments may be needed.
