I have gotten chin Botox more than three times.
With enough consultation, there were no recommendations for other procedures, and they administered the Botox according to my needs.
I have a peanut-shaped face, so I specifically asked them to make sure I would never get hollow cheeks, and they did that well all along. But recently the wait got so long that I got the injection a bit hurriedly, thinking of course they would do it well, and I ended up with a little bit of hollowing in my cheeks.
