Would I be able to see results in a square jaw Botox treatment, even in my case?

Hello. I am writing this inquiry because I have been very worried about my face shape.

I often get stressed because my jawline looks particularly prominent whenever I look in the mirror. People around me advised me to look into a simple procedure instead of surgery and recommended square jaw Botox.

I am writing to ask for your help as I have a few questions due to a lack of precise information. First, I would like to know who is the most recommended candidate for square jaw Botox. In my case, I am not yet sure if my bone is prominent or if the muscles I use for chewing are simply overdeveloped.

If I were to receive square jaw Botox treatment due to a muscle issue, I would appreciate it if you could explain roughly the process by which the effects appear and what precautions I should take after the procedure.

I know you are busy, but I would appreciate a detailed response. Have a nice day!
