Can I create a smooth jawline without worrying about side effects from square jaw Botox?

I decided to get Botox after much consideration, as I felt that the masticatory muscles I use when chewing food were unusually developed. I heard that even a slight slimming of the face shape can drastically change one's appearance, so I am looking to try the power of Botox; however, perhaps because it is my first time, I have quite a few concerns.

My biggest concern is one of the side effects of Botox: sunken cheeks or unnatural facial expressions. Although the directors at Maypure are highly skilled and will inject the correct amount of genuine product in the appropriate locations, muscle movements vary from person to person. Therefore, I would like to be aware of and prepared for any potential side effects that might occur.

Aside from avoiding hard foods after the procedure, are there any other special precautions I should take to prevent Botox side effects? I want to achieve a slimmer face line as my muscles naturally shrink, and hearing actual reviews would put my mind at ease. I simply want to become beautiful safely and satisfactorily, so I look forward to hearing your valuable experiences!
