Masseter Botox caused extreme tightness on one side of face

Question

When I smile, one side of my face feels extremely tight and my cheek has sunken in on this side. Underneath the eye scrunches and wrinkles. The smile line has also disappeared on this side and my smile is still weird. My face was perfect and symmetrical before this I’m gutted.

This result is not expected if only the masseter was injected. Photos would be helpful to be able to see what is going on, but luckily all effects of Botox resolve in 3-4 months, so this should not be permanent.

Hi @Liz599807, I am sorry to hear about this. It is possible that the botox was inadvertently injected into one of the smile muscles. I am not sure how long ago the injection was Botox typically lasts 3-4 months. Best of luck, Dr. Ghazizadeh

What you are describing is not typical from a masseter Botox treatment.  I encourage you to return to your injector to discuss your concerns.  The effects of Botox are temporary and typically last three to four months, so the unwanted effects should gradually improve with time.
