'Laser lipo' and SmartLipo™, like all thermal liposuction methods, use tremendous heat to burn the fat before removal. SmartLipo™ generates this heat by using laser energy. VASER liposuction is similar to Smartlipo, but it works by ultrasound, and does not damage the tissue to the degree that SmartLipo™ does. The unfortunate by-product of all of this heat is burning and coagulation of the blood vessels and supporting tissues that keep the skin and remaining fat healthy and supple. An inflammatory process follows the death of these fat cells, which leads to dermal adhesion and scarring. In rare cases, these burns can be so severe, as to actually burn through the outer skin leaving horrific scars. Ultimately, this heat-induced trauma can result in the contour irregularities, often associated with a "bad" liposuction outcome, with wavy, uneven skin that appears damaged and unnatural.
