What is Vaser Liposuction?
Liposuction process using the four-dimensional laser (Vaser) is a procedure that delicately removes fat around the muscles. 4-D laser, unlike other old technologies, provides the doctor delicately sculpting the muscles while also rendering the muscle shape sculpting both in motion and stable.
Vaser Liposuction technology also makes jaw muscle shaping possible along with removing fat intricate places that other techniques cannot reach like arms and inner part of hip.
Vasar liposuction procedure steps 
Surgical incision
Surgical incision is done just as small as canule can enter, cannot exceeding a couple of milimeters. From this incision, a saline solution that thickens the to be removed fat tissue is injected. This solution has a few functions including below:
1. Numbs the area
2. Reduces blood loss by pushing away veins and compressing them.
3. Reduces bruising and inflammation risk.
4. Increases healing rate.
5. Facilitates aiming for the fat tissue to be removed
Vaser Liposuction and Muscle Esthetics
The doctor puts another canule that aims for the fat tissue and turns fat into liquid cells so that the fat can be sucked without damaging the nerves, tissues or veins in the liposuction area.
The difference between other techniques and Vaser technology is its capability to aim selectively for fat cells; fat that is located between muscle fibers, and thus differentiating itself from other techniques that aims for visible fat and shape the muscle while both in motion and stable. Since the muscle stays motionless during surgery, it cannot be shaped in motion.
Closing the surgical incision
The cannula gets retracted and surgery ends with success after small surgical incision gets closed.
Risks and complications
There are some risks and complications of esthetic surgeries you need to know that involves using powerful gadgets like laser, vaser and other methods even if they are rare: 
Risk of bleeding during surgery
Risk of bruising or inflammation
Risk of non-fat tissue damage (redness and inflammation).
Risk of infection during or after surgery
Risk of hrombosis during or after surgery 
Risk of burns if the doctor using the device is inexperienced.
But don’t forget that treatment with vaser reduces the risks to minimum.
