Facial Asymmetry and Paralysis After Botox

Sorry to hear that you're not happy with your results. I suggest you see your injector for a follow up. By this time, the results should have diminished.

Dear ABCox
BOTOX is best from the eyes up. It can be used in the lower face but only with the utmost care. It is all too easy to get unwanted facial muscle paralysis.
The face is one of the most important organs for emotional perception. There is evidence that the motor tone of the muscles of facial expression feedback into the emotion centers of the brain and influence how we feel.
It appears that imbalanced BOTOX treatments can create an adverse emotional state. I have seen individuals with "BOTOX Drift" with what appeared to be a minor smile weakness. Yet they were so emotionally disabled that they could not work until the effect disappeared.
The longevity of the effect will vary with the actual amount of BOTOX that was used. However, as others have noted, it can take 3 to 6 months for these effects to resolve to the point where you are no longer self-conscious of your appearance.

I read your question, and review.
I'm sorry you had dissatisfaction with your last BOTOX treatment.
Frankly, I do not see any significant "paralysis" or assymetry after your treatment. There may be less show of your upper gums when you smile, but your smile is not crooked or unattractive. If you post a full face frontal picture, I'll be happy to give you my thoughts.
I have not seen the effects of BOTOX have any permanency, so your big smile will return shortly.
Best regards.
