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. 

Liposonix is a
non-invasive procedure that is designed to remove stubborn fat that does not
respond to diet and exercise. You may feel slight tightening in the area that
is being treated. My suggestion is to consult with your doctor to make sure you
are a good candidate for Liposonix.

Liposonix uses focused ultrasound, just like Ulthera or Ultherapy.  The sound waves can be focused at very deep tissues with pinpoint precision.  There is no question that the technology works, and works well, but their are some limitations.  Pain management can be a real problem, and without proper anesthesia, the complete treatment cannot be completed.  One can dampen the energy, and increase the number of passes, but this will increase the cost and take much longer.  It should also be noted that diet and exercise are very important, because without it, the patient will not see as much improvement, and certainly will not retain the loss.  We have removed up to 3 inches with one treatment!
