I am concerned about the timing of square jaw Botox injections.

Hello. How do you all schedule your jaw Botox injections? It feels like just yesterday I got the injections with mixed feelings because my angular jaw was so stressful every time I looked in the mirror, but now it's already time to consider my third treatment. When I got my first injection, about a month later, people around me kept asking if I had lost weight. As the volume of my jaw muscles decreased and my facial lines softened, my impression definitely changed. However, after about four months, I feel the muscles slowly growing back, and it’s upsetting that my jaw seems to be returning to its old square shape. I've heard that the peak effect usually appears 1 to 2 months after the procedure, and the results last about 3 to 6 months. How often do you usually get yours? I'm curious if you experienced any discomfort while getting them, and how often you all manage your maintenance! Thank you in advance!
