Once you have had your injections, the effects of Botox can last three to four months – some patients can see a full year of success with Botox. The recommended interval for treatment should coincide with your regulare check ins with your plastic surgeon. You can add more Botox every three to four months if needed. You may find that as your facial muscles begin to train themselves to contract less, the period of time for each treatment may be extended longer after each treatment. Individual results may vary. Please come in and see Dr. Hirschfeld for a free initial consultation and he can help you determine how often you should come in for additional Botox treatments.
