What is my best option for reducing my masseter muscles?

If the cause of the hypertrophy is related to the masseter muscle, Botox/Dysport can be used to paralyze the masseter and eventually cause atrophy and slim the jawline. Treatment at the masseter muscle is considered off-label so it is important to see an experienced injector.

Clinical Context

Botox works by relaxing the masseter muscle so it gradually shrinks from reduced use, rather than shrinking the jaw directly. Most people begin noticing a slimmer jawline within a couple of months as the muscle de-bulks. Because the muscle can rebuild once the effect wears off, repeat treatments every few months are usually needed to keep the slimmer contour. Results vary depending on muscle size and dose used.
