What exactly are the benefits of Botox for reducing jaw muscles?

I am writing to inquire about the most unrivaled advantage of Botox in improving a square jaw compared to contouring injections or other lifting laser procedures.

Since it is a non-invasive procedure, there is almost no swelling or bruising, and the ability to apply makeup or wash your face immediately after the treatment is a major advantage of Botox for busy office workers. The fact that the procedure is extremely quick, allowing you to get it done quickly during your lunch break, also seems to be a plus. I am curious if the principle behind it is that it naturally reduces the volume of the jaw muscles to make the face shape slimmer.

I would like to make a decision after hearing a detailed explanation on whether this Botox procedure is a much more cost-effective choice than other contouring treatments in terms of cost-effectiveness and satisfaction. Please provide a response.
