Does the Skin Tighten Up with Liposonix?

Liposonix uses focused ultrasound for noninvasive fat reduction. Because it generates heat in the tissue, there is presumably some effect on collagen with tightening. Keep in mind that the treatment is focused at a depth of about 3/4 of an inch, and its specifically intended to have no effect on the skin for safety reasons. Having said that, I do believe that we are seeing some tightening with Liposonix, but if the skin is obviously loose then you may not be a good candidate. This is also true BTW for laser liposuction such as Smart Lipo; although there is some skin tightening, it is not very significant.

Tightening of the skin may be a secondary benefit of the Liposonix treatment and this adds promising innovations in the management of patients who wish to have non-surgical fat removal without liposuction. 

While it is not the main reason to use this device, our patients have noticed a modest amount of skin tightening in the areas that were treated with Liposonix.  There is no quantitative way to measure the degree of tightening, but based on our experience and patient feedback there is contracture from the heat generated by the device under the skin.
