You have two layers of fat beneath your skin: superficial, which is right under the skin, and deep, which is farther down.
During liposuction, the doctor makes a little cut in your skin and sticks a hollow tube called a cannula into the deep fat layer, since there’s less risk of damage to the skin when working on that layer. The cannula breaks up fat cells and then suctions them out with a vacuum; it’s common to lose a lot of fluids during the procedure as well.
There are four main types of liposuction. Tumescent is the most common; it’s considered the safest, since it limits blood and fluid loss. The doctor injects a lot of fluid into the fatty area to make the fat swollen and easy to remove. Although it can take four or five hours, it only requires local anesthetic.
Super-wet liposuction is like tumescent, but it uses less fluid and is usually done with general anesthesia or an IV epidural. It takes around two hours.
Ultrasound-assisted liposuction is done with a cannula that vibrates quickly and uses ultrasound energy to liquefy the fat, which is then sucked out. It’s an accurate procedure, but it takes a long time and carries the risk of burns.
Power liposuction, lastly, uses a motorized cannula that’s faster than manual liposuction.
