I would like to inquire about the cost and recommended number of Botox sessions!

Hello. I received square jaw Botox for the first time a few years ago. My face used to look angular and large, but about three weeks after the procedure, my jaw muscles softened and my facial lines became much slimmer, which boosted my confidence. I was particularly satisfied because the effects were clearly visible in frontal photos.

Now that time has passed, my jaw is starting to become slightly angular again, so I am considering a re-treatment. How often is it generally appropriate to get square jaw Botox? I am curious because I have heard that getting it too frequently can reduce its effectiveness. Are there any tips for maintaining the effects for a long time?

What is the typical reasonable cost for one session (for both sides)? I've noticed significant differences between hospitals, so I would appreciate it if you could let me know the recommended number of sessions, price range, and precautions.

I would appreciate honest reviews from those who have received Botox, including square jaw Botox, and please also recommend some places.
