Non-surgical cellulite treatments do produce visible results, but those I have seen are temporary. To maintain improvement in cellulite using laser, ultrasound and other non-surgical techniques that have been thoroughly investigated require continued treatments to maintain your result. Long term experience in Europe where most of these treatments were developed have often been disappointing.
Have an open honest discussion with your doctor and ask to see results on patients he/she has treated. Confirm what results you can expect. if you need additional treatments what will be the cost. Ask the doctor how many treatments you will need.
These treatments work by altering blood flow and shifting fluid. Permanent tissue changes resulting in permanent cellulite removal have not yet been documented by histology or microscopic examination, in my opinion.
