Hi Kellie. Thanks for writing. Our expectation for our jaw shaping patients is that they should visit every 4-6 months, 2-3 times per year. We do have patients that exhibit a nice reduction after the first treatment, but true muscle atrophy (shrinking) occurs slowly over a period of time (1 year). To get the most out of this treatment, remain consistent in your visits. Good luck.
The photos at the link below show excellent progress for this procedure.
