Even though I said that the change would be great because I was the type of person who would raise my muscles when my jaw clenched, there was no change when I got Botox for the square jaw.
But one year later, suddenly, one day, my chin looks too square. (I just took a picture as usual, but the chin keeps coming out.)
It must have worked. So when my chin looks so ugly, I get Botox for my square jaw about once a year.
But there are hospitals that recommend double the dose if you have this kind of muscle. It doesn't really matter, so you can just be normal.
