It was my first chin Botox, and they said I had a lot of chin muscle, so they recommended double the dose.
If you lie down and wait, the doctor comes in, injects the Botox, and that's it. And then the next day it popped out like I had a candy in my mouth. They say it could be due to an insufficient dose or a lot of chin muscle, but recommending double the dose and then having this happen....
