Does Botox work to erase the lines at the corners of the mouth and can it also lift the outside corners of the mouth?

Botox can be used to treat lines in the area at the corners of the mouth, but this is considered an off-label use. If injected correctly, it can significantly improve the lines located there. I recommend that you use a very highly competent injectionist when treating this area of the face with Botox. There are multiple complications that can occur, including affecting your speech as well as your smile. It can make your smile look asymmetric. I’ve been injecting this area for over a decade and I do feel that it will often allow the corners of the mouth to go up a couple of millimeters, which will improve individuals that have the corners of their mouth turned down.
