It’s not Botox that creates the really weird faces. More likely, it is the overuse of fillers or other procedures. Fillers make the lips huge. Botox and the other neuromodulators are more subtle and only temporary. They can sometimes freeze the face and look weird because of that, but they don’t add volume (and they only last a few months).
Regardless....whatever it is it’s unattractive as far as I’m concerned.
