I had botox injected into my crows feet/ around lower orbital rim. 2 days later, I can't smile all the way. Did the injector hit zygomaticus major/minor? The corners of my mouth do not come up. Thank you for any help!
Did botox migrate?

Botox smile changes
Dear citygal38, Botox does not migrate. It can diffuse for a small area, around the injection site. Thus, when Botox is injected around the eyes for crow's feet, some un-intended muscles can be affected. This happens if the injections are a bit too low, or if the number of units injected is a bit high, or if the Botox is used in a higher dilution. In your case, it could be the muscles resposible for raising the upoer lip, as in smiling. Fortunately, if this is the case, it resolves within a few weeks, spontaneously.
