How often should I schedule square jaw Botox treatments near Hongdae?

Lately, I’ve been stressed because the angular part of my jaw seems particularly prominent whenever I look in the mirror. Perhaps because I like chewing tough foods, my jaw muscles feel much more developed than before. I’m looking for a dermatology clinic in the Hongdae area to achieve a slimmer jawline, and naturally, the most popular procedure, Botox, caught my eye first. I heard that it is the most cost-effective option for improving an angular jaw.

However, since this is my very first time getting this, I would like to familiarize myself with the characteristics and precautions regarding square jaw Botox beforehand. I am curious about how long the effects typically last after a single injection, and what the ideal interval between treatments is to maintain a slim line. If there is any advice or tips from those who have successfully maintained the effects for a long time through regular care, please feel free to leave a comment!
