I'm curious about the recommended number of Botox injections for a square jaw.

I have very little fat on my face overall, but my lower jaw is developed, making my jaw look even more square. Because of this, I constantly worry about angles when taking photos and try to look blurry whenever I look in the mirror. However, it seems like this square jaw isn't shrinking over time but rather getting bigger. I must be using my masseter muscles too much. I’ve heard that square jaw Botox is very common these days, so I am writing to inquire because I would like to improve my protruding jaw with it. Generally, how often and at what intervals is it recommended to get protruding jaw Botox? Since I work, it is difficult for me to get procedures that require a lot of time for the treatment or downtime. Also, I am preparing to move, so I have too many other things to worry about. If post-Botox care is complicated and difficult, I would like to postpone it until after the move. Will post-procedure care for square jaw Botox be difficult? I am also curious to know how many sessions people who manage their square jaws with Botox like me purchase in a package. Please share your honest and candid thoughts.
