Botox is temporary and lasts four to six months. If you like the results, you may decide to continue with several treatments a year. Years of using botox can mean you'll need less and less maintenance over time. With the right frequency and amount, your muscles become less strong and you may not need as much Botox or need it as often, Farber says.
When the muscles are “trained” not to move, it helps with the aging process and prevents wrinkles. Botox, and several other neuromodulators, have been approved by the FDA for more than 20 years. Botox has been shown to be safe for both short-term and long-term use. Data for the treatment of wrinkles with Botox only date back about 15 years.
However, Botox for wrinkles uses a much lower dose than patients receive for other conditions, such as muscle spasticity. No significant safety concerns have been identified in people receiving higher doses of Botox for those other problems, further supporting their safety. The effects of Botox usually last up to three to four months. Therefore, the recommended treatment is once every three to four months.
However, if the facial muscles begin to train to contract less, the time period of each treatment can be extended by more than three or four months. For this reason, it is essential to work with a surgeon to create a personalized treatment plan.
