I had my masseter Botox in 21.8.23. It slimmed my face very much. I got 27.5 units per side. But it didn’t pass. My muscles feel strong as before but look VERY slim STILL! doctor said it wears off after 3-4 months and I’m stuck, I want my old square face shape!! Will it last forever?? I can’t stop having panic attacks about it. If it’s relevant I wear a retainer at night (got my braces off a year ago)
