What are the limitations of BOTOX ® injections?
Unfortunately, BOTOX ® injections are a temporary solution for the treatment of dynamic wrinkles. The effects of the injections last from two to four months. You will need to have injections about three times a year. Early clinical studies indicate, however, that the duration of treatment benefits increases over time, so you may require injections less frequently in the future. Also, the duration of effect varies from patient to patient.
