- A natural body contour
- Fast recovery
- Reduced pain/downtime
- Reduced bruising and swelling
Vaser is a better technology to prepare the fat for removal. Laser has its merits, but over a large area, Vaser is king. Laser is good for arms, mid neck under the chin. For abdomen, flanks, braline, Vaser is king. We use both on the same patient, and take advantage of both of their ability to shrink the skin.
All liposuction medthods are divided into 3 stages:
stage 1 - infiltration of tumescent solution to dramatically reduce blood losses, decrease the pain and increase the accuracy of liposuction
Stage 2 - energy application (Ultrasound with VASER / high direct heat with laser)
Stage 3 - evacuation by passing tubes (cannulas) back and forth through the fat on high suction
Standard liposuction consists of stages 1 and 2 and is the way MOST liposuction is still done. VASER uses ultrasound to literally shake fat loose from behind fibrous areas such as backs and male breasts. It is associated with little damage to blood vessels and nerves. But the fat needs to be removed by suction (stage 3). Laser liposuction uses a very hot fiber to literally cook everything it touches. The resulting fatty emulsion left by the hot fiber needs to be then removed by suction just like every other suction.
Frankly, the literature does NOT support the superiority of laser liposuction to ANY of the liposuction method and there are plenty of laser liposuction disasters out there. Only 3% of Plastic surgeons use laser liposuction. VASER liposuction is much safer and is used by a much larger number of surgeons but it takes additional time to perform. As result, the vast majority of Plastic surgeons do not use either method.
Vaser uses ultrasonic energy and laser lipolysis uses laser energy to mel fat. They are two methods that use heat to dissove fat .
Your question touches on a controversial topic. The first thing to know is that liposuction, whether with VASER ultrasound, laser (Smart Lipo, Slim Lipo, etc. etc.) is still liposuction. The addition of lasers increases the odds of complications such as skin burns though it is often misleadingly advertised as safer. It is the surgeon not the technology that makes the most important difference. If by "laser-based fat loss" you mean Zerona, a nonsurgical procedure, there is even more disagreement because many believe that it is the diet supplement that produces the weight loss and that the low-energy lasers have nothing to do with it other than placebo effect. There is a nonsurgical procedure that produces very localized fat reduction with a high degree of precision, called Liposonix.
