Laser liposuction is effective in removing fat and was deemed as such by the FDA in 2007, states WebMD. The maximum fat removal typically allowed is 5 liters. There is debate by experts on whether the skin-tightening result is better with laser liposuction than with traditional liposuction.
Laser liposuction is similar to regular liposuction, except that is uses a low-energy laser to melt the fat before it is suctioned out of the body, explains WebMD. This may result in skin-tightening, as it boosts collagen renewal. Many plastic surgeons believe in this effect, although others believe it is not much different than regular liposuction.
As of 2015, the only scientific study that compared regular liposuction with laser liposuction found no substantial differences in results, according to the American Society of Plastic Surgeons.
Some possible complications and risks specific to laser liposuction include laser burns and bruising, warns WebMD. All types of liposuction carry other risks such as scarring, irritation, loose skin and poor results. Major complications include blood loss, blood clots, punctured organs and death.
Patients interested in liposuction should consult with a board-certified plastic surgeon to find out what kind of liposuction is the most appropriate and effective procedure for them, advises The American Society of Plastic Surgeons.
