Botox would not slim your face UNLESS you had problems with clenching to begin with because it's the clenching the activates your masseter muscle making it look wider.
I swear some of you just want to chat tit for no reason, if she wanted a face slimming there are face slimming options such as the fat dissolving injectables in the cheeks (which she literally showed herself getting but in her neck).
People love dragging influencers for not being transparent about cosmetic procedures but are so quick to call them liars even after they are transparent, so now what????
Edit: that being said, Flossie if you read this, getting botox in your jaw long term is going to make your jaw sink into your face and it'll be even worse, go get a night guard from a dentist instead xo
