I Had a Botox Done on my Jaw Line, but Now when I Am Laughing my Upper Lip Looks Alot Smaller?

    From reading your additional post, you seem to have already figured out what has happened.  I would wait this out until any further treatments are performed.

Botox used for jaw line usually refers to wide jaws when Botox is used to make the muscles on the side smaller - to narrow the appearance of the jaw.  If this is what was done then it's extremely unlikely that muscles that affect the mouth have been affected.  Can you provide more details?

Hi Roby.  Without the before and after pictures, it's difficult to say whether what you are seeing is related or perceptible to a third party.  Injections of Botox in the lower face can cause changes in the smile if the product migrates to muscles that were not intended for injection are affected.  Best way to address your concern is to return to your injector and check out the before photos.  Good luck.

It is difficult to answer your question without more details, however, injection of botox around the chin and lips can cause a change in your smile. Often times this is temporary for a few weeks until the muscles adapt to the change.

Botox last for approximately four months, and the region should return to normal at this time. 

It is very difficult to asnwer your question without first knowing the amount injected into your masseters and injection technique. You should consider posting photo's of before and after treatment for better assessment.
