For those recommended for Botox who are concerned about a square jaw, is the effect certain?

My jaw muscles are a bit developed, so I am considering getting Botox. I am writing this post to find out how effective it is.

I've seen that Botox is often recommended for square jaws, so I want to know if it actually refines the facial lines!!

I'm also curious how long the jaw-slimming effect of Botox lasts.

I'm hesitant about the change being too obvious, so I'd like to know if the change is natural.

I’d love to get some tips for those of you who have received Botox for a square jaw by letting me know about the extent of the changes or your satisfaction level.

I'm worried about my square jaw and I really want to resolve this problem.
