Eyelid Droop After Jaw Botox, when is the Right Time to Do Botox Agaiin?

It would be exceedingly difficult to inject Botox in the masseter muscle and have it diffuse to the eyelid (levator aponeurosis).  I would have your lid ptosis (eyelid droop) evaluated by a qualified physician before trying to determine your next Botox treatment.  

I have never heard of having eyelid droop after Botox injections to the masseter muscles. Follow up with your provider for more education and assessment of what's happening.

           Upper or Lower Eyelid?  The jaw is pretty remote from the upper and lower eyelids.  However, if you were injected for masseteric hypertrophy and were injected high, this might affect the lower eyelid.  Waiting is the safest response, but depending on what you want and where the doctor injects, this may not be unreasonable.

Injection of botox into jawline does not cause an eyelid droop. You should go back to your doctor or an internist to find out the cause of eyelid droop and only after have your next botox treatment.

Botox injected along the jawline or into the masseter muscles should not cause an eyelid droop.  You should return to your doctor for assessment of the eyelid droop.
