Botox's Gone Wrong (On my Chin and Jaw)? (photo)

You should notice your lip depressor function and your smile symmetry return very soon.  As you noted, muscles that were not the intended target were treated with Botox, but it should wear off this month since you are already 3 months from treatment.  

the number of units used to correct the jawline and the chin (60 units) is on the high side in my opinion. the greater the number of units used the longer it will take for the Botox to wear off. its not permanent. just be patient
