Fat cells ruptured via cavitation inch loss treatment will never grow back, so results gained are as permanent as with those from surgical liposuction. If you carry on with your new healthy lifestyle (portion controlled meals and regular exercise). After a period of 4-8 months, the body will naturally breakdown and remove the ruptured and unused fat cells.However, if an individual continues to overeat/under exercise the remaining fat cell can still increase in size as is also the case with surgical liposuction.
