If you are receiving laser treatment to remove fat, multiple sessions will be needed to ensure you reach your ideal results, often around 8 sessions once a month will be enough. With cryolipolysis treatments, the fat will be eliminated permanently, but it cannot stop new fat cells from developing and takes up to 4 to 6 months to see the full effects of the results. Ultrasound fat removal is the same as cryolipolysis in that the fat cells that have been removed do not grow back, but may take 1 to 3 sessions every two weeks to see the desired result. Fat-dissolving injections will typically take 3 to 4 sessions every 2 weeks before you start to notice results, and many patients will receive 6 to 8 sessions total, however, results from the injections can last up to 2 to 4 years.
