Can I have laser lipo (Smart Lipo) done under the chin twice?

Yes. The Smartlipo procedure can be repeated one year later. You typically get the full results of the procedure in 12 months.

Liposuction can be performed in any area twice, however after one treatment the amount of skin retraction that you can expect will diminish significantly. I would temper your expectations for skin tightening quite a bit following the first attempt at liposuction.

Dear smicklin,
it is hard to tell for sure without an examination. Generally speaking, it is possible to get liposuction twice. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.
