Laser scar removal surgery is one of the most popular uses of laser technology in the medical arena. Laser scar removal aids in scar reduction and in many cases helps in preventing the scar from reoccurring. Scarring is the result of a disrupted wound-healing process. For example, a keloid scar is a scar that has developed an abundance of collagen which ultimately collected as a mass and caused scarring. Laser scar removal works to remove and reduce the appearance of multiple types of scars. Keloid scars, hypertrophic scars, and atrophic scars can all benefit from scar removal surgery. Unfortunately, not every patient will be a candidate for this ground breaking surgery. Certain skin conditions such as psoriasis, dermatitis, and cystic acne can interfere with the procedure. The majority of laser scar removal surgeries are done with the use of a local anesthesia on an outpatient basis. The procedure can take from a few minutes to one hour.
