Hello,To answer your question honestly, the smart lipo of the chin should never be repeated. This type of procedure is done once and is done. Fat cells which are removed with the smartlipo are gone forever and they never come back. Smartlipo also helps with the skin tightening of the chin. If it is done correctly then you will not need to get the treatment again. Hope I have answered your question. Good luck.
Yes, you can have SmartLipo in the same area more than once. However, when you had previous surgeries, you don't have virgin fat anymore ( fibrosis instead)
