Laser liposuction, also known as laser lipolysis, has the risks of bruising and minor pain. It is most effective when performed in concert with traditional liposuction, which also has the risks of infection, bleeding, blood clotting and adverse reaction to anesthesia, as stated by Healthline.
Laser lipolysis targets fiber-optic lasers at specific points on the body to melt away fat using heat. Traditional liposuction utilizes vacuum suction to remove fat from the body. Laser lipolysis has the added benefit of spurring collagen production, leading to skin that is more taut. A study of clinical results from over 2,000 patients over three years found that the most significant complaints associated with the laser procedure included bruising and low levels of pain, notes Healthline.
Combining laser lipolysis with traditional liposuction results in bodies with less fat and tight skin, which is an improvement over the sagging skin that can accompany traditional liposuction done in isolation. The risks of asymmetry, contour irregularity and fluid buildup beneath the skin that accompany traditional liposuction remain when laser lipolysis is added to the process. In general, though, the research finds that laser lipolysis is a safe outpatient procedure with a quick patient recovery period, according to Healthline.
Skin infections are possible but very rare, and they can be lethal if the infections are severe. Seromas, which are temporary fluid pockets, sometimes develop under the skin, but the fluid accumulation can be drained. The skin can also appear wavy, withered or bumpy because of reduced skin elasticity, uneven fat removal and unusual healing, where contour irregularities may be permanent, reports Mayo Clinic.
Inflammation sometimes occurs if it takes a long time for the swelling to go down. Bad bruising is common in patients who have been taking aspirin or anti-inflammatory medicine, as well as in patients who have bleeding disorders. Numbness and nerve irritation may be experienced temporarily in the area of the procedure, states Medical News Today.
