I would like to inquire if Botox would be effective for my angular square jaw.

Hello. Lately, I am concerned because my jawline seems unusually angular and prominent whenever I look in the mirror or take a profile photo. It feels hard to the touch, but I suspect it is due to the overdevelopment of the masticatory muscles I use when chewing food, rather than a bone issue.

As shown in the photo I uploaded, the line leading to the tip of my chin is quite angular when viewed from the side. I am writing this post because I am wondering if it is possible to achieve a slimmer face with just Botox treatment for a case like mine.

I have never had jaw Botox before, so I am a little worried about potential side effects, such as hollowing out my cheeks or my salivary glands becoming more prominent after the procedure. It would be a great help when I visit for a consultation if you could let me know how many units are typically needed to be effective for this type of square jaw, and what the treatment schedule should be.
