It's been 10 years since I got botox for my square jaw because Xeomin said I'm not resistant to it. I just go to the hospital once a year and get botox for my square jaw. If I don't get it, my face immediately turns into a square shape, so if my chin looks good when I take a picture, I go to any hospital. I've rarely seen a hospital that can't provide square jaw Botox, so I used Xeomin Botox.
