Thanks for your question. This is a question that we get asked often by our patients. As far as Botox treatments, muscle hyperactivity would likely require treatment 3 times a year. Botox effects can last anywhere from 4-6 months and with recurrent treatments, this will lead to mild atrophy of the muscle, and some prolongation of Botox's effects. Botox effects are never permanent, however, if you elected to stop, your muscle would hypertrophy back to its original size. These are advanced techniques so be sure to get an experienced cosmetic dermatologist consultation for recommendations and treatment options. Results are expected to start in 2-10 days and peak within 14 days after injection. In some patients, it may take up to 30 days to reach full results. On average, results will last for 4-6 months.
