Square jaw Botox treatment: Recommended? Not recommended?

I like chewing gum, so my jaw muscles are particularly developed.

I felt like my impression looked too strong. I wanted to improve my look naturally rather than through excessive procedures, so while looking into it, I thought Botox would be the right fit.

I think a major advantage is that since it is an injection procedure, you can return to work immediately without a separate recovery period. However, I am curious if there are any restrictions on daily activities, such as drinking or exercising, after the Botox treatment, and approximately how many months after the procedure the effects are at their best.

As a working professional who prefers a clean image, I am wondering if this is a procedure I can undergo without feeling burdened. It would be very helpful for me to make a decision if those who have personally experienced it could tell me how noticeable the facial lines were in being refined. I would also like to know the cost.
