With Ultrashape, will the fat cells return? How are they expelled? How lasting are the results?

Treated fat cells are permanently destroyed

The body breaks down the destroyed fat cells, just like it breaks down other fat. The waste is then eliminated naturally. Treated fat cells are permanently destroyed, so the results are long lasting. You will still have fat cells in other areas that can increase in size, so it is important to maintain a healthy, active lifestyle.

UltraShape is a nonsurgical fat-melting treatment with no downtime and no pain. It works by sending ultrasound energy (not thermal energy or heat, which is the technique used by many lasers) to targeted fat within the subcutaneous layer, which lies deep in the skin. There, this ultrasound energy vibrates or shakes the fat cells until they fall apart and are liquefied, thereby selectively destroying these fat cells. The disintegrated fat cells then pass through the liver. So your body processes it just like you ate a fatty meal, and it’s excreted naturally as waste.There is no damage to the surrounding skin or tissues. No anesthesia or sedation is necessary. The treatment is completely painless.
Patients experience visible body shaping—with no significant bruising, swelling, or any discomfort. And because the fat cells are eliminated, long-term results can be maintained (provided patients stick to their healthy diet and exercise regimen).
The average treatment regimen is three sessions, spaced two weeks apart, though the number of appointments may vary depending on a patient’s individual needs and goals. (Treatment time can take anywhere from 10 to 50 minutes depending on the size and number of areas treated.)

Ultrashape and other Non invasive Fat Devices

Fat is expelled through the lymphatic system.  The results are 20% after 3 treatments.  This is best for small problem areas.  Best, Dr. Emer.

Questions about Ultrashape

Thank you for your question. Ultrashape uses ultrasound waves to "shake" fat cells until they rupture, releasing their contents.  Your body then metabolizes this fat for energy; it is not expelled from the body.  The fat cells that are destroyed are gone permanently, but remaining fat cells retain their ability to grow into the space the destroyed fat cells used to occupy. This means to maintain results you need to continue with a healthy lifestyle that includes regular exercise and healthy eating habits.  In my practice we have gotten some pretty amazing results with this device!  I hope the same for you should you undergo treatments. Best of luck to you!
