[Botox] Side effects of square jaw botox

I was satisfied with square jaw Botox once with an imported product a few years ago, so I got another injection with a domestic product about a year ago. I don't know if it's because of the difference in the type of Botox, but I actually had the side effect of my square jaw muscles getting bigger...; When I bit my teeth, they popped out like candy, so I went to the hospital and they told me that my jaw muscles were too strong so they just needed to give me more Botox. I added more as I said, and luckily it went in, but I was so stressed out that I didn't want to get it again haha. Many people say that square jaw Botox is a really simple procedure, but I wanted to let you know that there are side effects like this.
