How Many Units Of Botox For Face Slimming?

By February 27, 2023 No Comments
Botox injections—while typically used to help treat and reduce wrinkles—can also help slim the face when injected into the masseter muscle on either side of the face. It is particularly effective for people who have overactive jaw muscles or a prominent masseter muscle that makes the face look wide. When patients come in interested in the procedure, they often ask, “How many units of Botox for face slimming?’

How Much Masseter Botox Do I Need?

On average, 15 to 20 units is the average masseter Botox units that can effectively slim the face. However, people with especially big or strong masseters may require more, potentially up to 30 units per side. Additionally, Botox can help reduce teeth grinding and symptoms of TMJ. In this case, more Botox is necessary since areas outside of the masseter, or other areas of the muscle are also treated.

How Often Will I Need Masseter Botox Injections?

On average, Botox injections need to be refreshed every three months. However, based on your specific concerns and how quickly the body breaks down Botox’s effects, it may require sooner injections. Most people can expect to undergo masseter Botox injections three to four times a year.


Ultimately, your injector can help determine the number of Botox units necessary for face slimming. If it is your first time getting masseter Botox, your injector may want to evaluate your results after two or so weeks. If the results are not quite there yet, they can administer more units of Botox.To learn more and schedule a consultation, call us at 425-775-3561.
