Fat-dissolving and skin-tightening procedures for body contouring that are less invasive can seem oh-so-appealing when weighed against other options, such as liposuction. Some of the latest innovations include mesotherapy (lipodissolve), which involves the injection of various cocktails into the skin to dissolve fat, Thermage (also known as Thermacool or Thermalift), which uses radiofrequency to tighten facial skin for a "nonsurgical" face-lift, and LipoSonix, which uses high-intensity ultrasound to target and destroy fat cells.
