How much Botox do you need to improve a square jawline?

Bethany Frenkle's results are quite impressive. The Botox changed her look tremendously, but she says she's been having Botox injections in her jaw for years. Will I be able to see results from the first session or do I have to gradually build a rounder face shape through years of Botox?

Enlargement of the masseter muscle can make the face look square and fuller lower.  We use Botox to decrease the masseter muscle to decrease its size, which gives a slimmer lower face.  Usually it takes 2 to 3 sessions at 3 months apart to see the change.
