Any techniques that can damage underlying fatty tissue, can have the undesirable side effect facial wasting. I have seen one patient after Thermage procedure who reported loss of facial fat. I have not personally seen any patients after Smart lipo who reported the same, however, it is theoretically possible.
However, it is also important to remember that during facelift procedure the surgeon usually uses electrocautery to stop the bleeding. Electrocautery can also destroy small amounts of fatty tissue around the blood vessels that are cauterized.
With better understanding of facial anatomy and with better understanding of value of maintaining facial fullness, we start looking at new technology with slightly more skepticism.
I believe, there is still a role for laser lipolysis, like Smart lipo, in improving the shape and contour of the neck, I'm not confident that I see a great benefit for Smart lipo in improving the shape of the face.
