Smartlipo is one of several laser liposuction techniques. The arms are a very visible, small area with many vital structures. Liposuction of the arms requires small cannulas, delicate technique and good skin tightening for a good result. Large cannulae and agressive technique in the arms can cause unsightly skin irregularities and may cause injury. The benefit of laser liposuction (I use SlimLipo) like Smartlipo, SlimLipo, Coolipo and others, is that the laser melts and liquefies the fat so that removal is easier with tiny cannulae. The heat from the laser also tightens the skin which is very important in the arm. Laser liposuction is very new and not widely practiced yet. It is crucial that you consult a board certified plastic surgeon with experience in this technique. Many new users are simply not yet experienced enough to treat the arms--there are also many non board certified doctors offering these techniques--avoid them.
