- Technology used to achieve fat reduction
ReBorn uses medical grade LEDs, while Vanquish uses radiofrequency energy. Both these treatments target heating of the fat cells to at least 42 degrees to induce fat cell destruction, and cover a large area to be treated.
Coolsculpting, on the other hand, cools the skin and fat tissue significantly (by more than 40 degrees) in order to induce injury to fat cells while sparing the skin and adjacent tissues. Some people find Coolsculpting more uncomfortable due to the extreme cold sensation.
- Treatment areas
Vanquish can be used for the abdomen, flanks, back, and thighs. ReBorn and Coolsculpt can also be used for all these areas plus the arms as well.
Vanquish covers a wider area for circumferential fat loss, and the device is placed close to but does not contact the skin. ReBorn applicators are fixed to the skin, and the contact area is slightly smaller compared to Vanquish. Coolsculpt requires pinchable fat that can fit into the handpiece, so it may not be suitable for everyone.
- Weight considerations
Vanquish can be used for most people without any restrictions on BMI. ReBorn is not recommended for those with BMI more than 30, while Coolsculpt is suitable for patients who are close to their ideal body weight.
- Possible side effects
Coolsculpt has a risk of paradoxical rebound enlargement of fat cells, which can happen weeks to months after the treatment. Moreover, once the rebound has occurred, there is little result or benefit from other non-invasive body sculpting procedures. In such cases, liposuction is the main treatment advised. There is also a risk of nerve irritation, numbness, and prolonged pain after Coolsculpt.
This paradoxical rebound has not been reported to occur with Vanquish or ReBorn. However, some people may experience tender lumps as part of the inflammatory process to remove damaged fat cells. These generally resolve after a few weeks.
- Long term results
Vanquish has been shown to have long lasting results. Patients studied up to 4 years after treatment maintained an average of 75% of their original reduction in waist circumference. As ReBorn targets destruction of fat cells in the same way as Vanquish via thermal energy, it can be assumed that ReBorn would have similar long-lasting results.
There was also a study on two patients several years after Coolsculpt was performed only on the left flank (love handle). The two patients still had reduced fat thickness on the left flank as compared to the right, despite changes in their weight over the years. Although the study was only done on two patients, it can be assumed that the effects of Coolsculpt are also long lasting.
