Laser Assisted Liposuction of the Arms. Our 39 year-old female patient underwent power-assisted liposuction and Laser-Assisted Liposuction (Laser-Assisted Lipoplasty (LAL) or SmartLipo) procedure to reduce the flabby skin (bat wings) under her arms. Power-assisted liposuction is the removal of the fat, while LAL (laser-assisted liposuction) is an innovative procedure for both removing excess fat and firming loose skin/skin tightening. It is minimally invasive and uses a single laser fiber that is introduced through a small cannula that has been inserted into a small incision. Liposuction requires considerable training and technical skill on the part of the surgeon, as well as an artistic sensibility. Its other name is “liposculpture” for a good reason.
