The first time I had Botox chin, I thought it was good because only the square jaw fell out smoothly. However, after the third time, it became a peanut shape, and although it wasn't that bad originally, it got worse because my chin fell out. Even though the doctor said it was not shaped like a peanut when it was placed, you can see this on the side of the chin. It seems like even the muscles are paralyzed.
