A:

Quick Answer

Laser liposuction melts excess fat in localized areas of the body by applying heat of varying wavelengths from fiber-optic lasers, explains Healthline. This minimally invasive procedure also promotes skin tightening by triggering collagen production.

During laser liposuction, the doctor makes tiny incisions and delivers low-energy waves by inserting a thin laser fiber through the incisions, states the American Society of Plastic Surgeons. He targets specific areas with stubborn fats. Once the fat melts, the doctor uses a small cannula to suction its liquefied form.

In comparison, traditional liposuction involves administering anesthesia and a saline solution to the targeted areas, creating a small incision, and inserting a tiny tube through the cut and into the fat layers below the skin, notes the American Society of Plastic Surgeons. The doctor moves the tube that is connected to a vacuum and slowly sucks out fats from the body.

Unlike traditional liposuction which causes loose skin, laser liposuction removes fat while making the skin tighter, reports Healthline. Studies suggest that laser liposuction is generally safe and effective, and it leads to fast recovery. Most participants in clinical studies did not suffer serious complications, but some experienced mild pain and bruising. Doctors recommend using both traditional liposuction and laser liposuction to create a contoured physique with firm skin. For optimal results, people should maintain a regular exercise regimen and a healthy diet.
