Ultrasound liquefies the fat within the cell and the heat creates a vapor that expands the cell like a balloon, which then bursts, and is permanently destroyed without damage to surrounding tissue and normal cells. It was discovered by scientists working on the reduction and destruction of tumors. The liquefied fat is released into the body where it is more easily absorbed by the body’s lymphatic system for immediate elimination, with proper hydration and detoxification.
RF alone, used for fat reduction, heats/and kills the fat cell, but then the body must break it down to eliminate, thus, taking longer to see actual results.
The same is true with Cryolipolysis, also known as "fat freezing" which is a procedure that involves the cooling of body fat to break down fat cells, resulting in a reduction of body fat without damage to other tissues, however, people who have used this method report severe pain during the first few minutes of the “freezing” process, as well as significantly longer period of pain in the “thawing” process. There have also been complaints of bruising in the treated areas, as well as numbness, indicative of affecting the nerves temporarily or, possibly, permanently. The elimination of dead fat cells can take 3-6 months to see results, if any, and in some cases, is significantly more expensive than surgical liposuction.
Radiofrequency or RF devices work by producing an alternating flow, which creates an electric field over the skin. The electric field shifts polarity millions of times per second, that causes a change in orientation of charged particles. This method is used in conjunction with our Ultrasonic Cavitation to encourage the production of Collagen and Elastin to assist the skin in becoming firm again. As with liposuction, the pockets of fat are reduced immediately, and it is necessary to support the skin as it recovers over the treated, reduced areas.
Focused thermal ultrasound techniques work by raising the tissue temperature above 56 °C, resulting in coagulative necrosis of adipocytes, with sparing of vessels and nerves. Passive heating of the skin may also induce collagen remodeling. There is no risk of surface burning, as with RF.
From a government research article, found at:
“Significant research and developments are being pursued in the area of non-invasive aesthetic applications. Focused ultrasound in these applications is directed within the first 2 – 20 mm of the skin and subcutaneous tissue (dermis – subcutaneous fat). Very small lesions of ~1 mm3 up to several 10s of cm3 can be produced. The approach may provide a safer alternative to liposuction for cosmetic applications (Moreno-Morega et al. 2007). Superficial tissue is exposed to HIFU leading either to a contraction of collagen based tissue (dermis) or to destruction of adipose tissue (Gliklich et al. 2007; White et al. 2007). A clinical system has been approved for fat debulking in the European Union and Canada (Fatemi, 2009). Depending on the device, as well as the cosmetic application, both thermal as well as non-thermal mechanisms within an ultrasound field are employed for these procedures. One of these devices is currently approved for clinical use in the USA (Alam et al. 2010), and others are in use worldwide. Long term utilization of this technology, as well as regulatory approval, is still evolving.”
