Is it possible to soften fat before liposuction?

There are anatomic areas that are consistently more fibrous in women: the upper back especially bra rolls, and the fat around the belly button. Fibrous fat cannot be changed to fluffy fat.  Upper back liposuction can be successful if there is significant fat in that area and the surgeon suctions aggressively.  This is not an easy area to suction. 
Numerous plastic surgeons in LA, including my own practice, are offering the BodyTite radio-frequency assisted lipolysis with exceptional surgical results without the excision, scars, or downtime.  Sedentary activities can be resumed in two to three days and full activity with exercise within two to three weeks.

In areas which are more fibrous or scarred down, certain cannulas with specially designed tips are used to soften the fat and release some of the tethering cords and harder tissues to make the liposuction more smooth and easier to perform. This is done during the procedure by the surgeon so there is nothing to do prior to your surgery. Hope this helps!Johnson C. Lee, MD Plastic Surgery@drjohnsonlee
