Correct. Botox does not build up or accumulate in your system over time. We recommend scheduling treatments approximately every 12-16 weeks, once the effects of the previous treatment have worn off. It is safe to have additional treatments in the same area once the effects have faded.   While it is also safe to have multiple treatments in different areas simultaneously, it is important to adhere to the recommended treatment schedule. We do not advise frequent or excessively early top-up treatments, and we will not perform them if we believe it is too soon for your next treatment. Following the recommended treatment intervals ensures the optimal results and safety of your Botox treatments.
