Will this procedure really help me scale down my thighs?

Laser assisted liposuction with Smart lipo provides added benefits to regular liposuction. Smart lipo and VASER ultrasound assisted liposuction melt fat and also produce some skin shrinkage. These techniques minimize contour irregularities associated with regular liposuction.

You can certainly try exercising and dieting however your thighs are probably affected by stored fat deposits that won't respond well to this. In addition, you may also be affected by loose skin. As a result, you may want to ask first if you have a lot of loose skin. If yes, then no form of liposuction will adequately address this. The fat may be eliminated, but you'll be left with more loose skin that will continue to make your thighs "jiggly". Loose skin can be removed with a thigh lift, which will also address unwanted fat. 

SmartLipo can decrease the thigh girth by reducing the amount of fat that envelopes the thigh muscles. "Jiggly" thighs can be a result of loose muscle tone or excessive fat overlaying toned muscles. before a patient decides to go thru the procedure it is important to understand and to clarify with your doctor what your main concern is. if its "jiggle" due to loss of muscle tone then its better to tone up the muscles with exercises and then seek another opinion for a possible SmartLipo. if the "Jiggle' is due to excessive fat that can be improved and then further skin tightening can be acheived with regular exercises

Using a laser liposuction device is a great option if you have moderate to good skin tone and want to reduce volume in certain areas.  I would stress that your weight should be relatively stable and that you maintain your balance of diet and exercise to maintain that.  To better answer whether Slim Lipo or Smart Lipo is an option for you, it would be helpful to have a picture to see.  Both procedures have a very high satisfaction rate.  Good luck.

Smarlipo and Lipo work by removing fat cells.  There is some tightening of the skin due to fibrosis of the underlying tissue and contraction of the collagen.  Smartlipo is great for targeted areas such as the thighs, hips, abdomen, chest (for men), arms, chin, etc.  

Any kind of liposuction removes fat to make an area thinner.
But it will not make you less "jiggly." In fact, with less "stuffing" in the skin, the perception of looseness sometimes increases.
Patients need to understand this. It makes people thinner, but not younger.
The claim that certain methods of liposuction tightens skin is as old as the procedure itself. And like miracle fountain of youth drugs, NOT ONE has ever been shown to achieve this. Ultrasonic liposuction and superficial liposuction have long been claimed to increase skin tightening. But this has never been proved. And at best, they might only make up for some of the increased laxity that results from the removal of fat of the procedure, but they would never increase the tightness relative to where someone started out before surgery.
SmartLipo is the latest fad liposuction procedure, claiming the ability to tighten - but without any proof. The buzz at the recent American Society for Aesthetic Plastic Surgery meeting was that SmartLipo was a gimmick, and the procedure is held in disrepute as a marketing device by many respected plastic surgeons.
So, if you want to be thinner, get lipo. But don't expect the jiggle to get better; you should even be prepared for it being worse.
