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.
