Botox Injections for Square Jaw

Q: Dr. Eppley, I had Botox injections for square jaw in the masseter muscles three months ago, 32 units each side. Now I dont like the way my face looks. It is heavy, not v-shaped with saggy skin and prominent cheeks. You are an expert. Is it reversible.? My jawline that was perfect is now like a jawline of an old person.

A: Botox in a reversible neuromuscular drug which achieves a temporary muscle thinning effect as the nerve input to it is decreased. However in the vast majority of patients the master muscles should return to its previous state of fullness once it has worn off in 3 to 4 months. I have yet to see Botox injections cause a permanent muscle thinning effect in just one injection treatment. This almost never happens or at least I have never seen it. Most patients who have this treatment for a square lower face or thick masseter muscles wish it would work with just one injection treatment,. I would need to see some pictures of your face to see what you looked like before Botox and now after for further commentary/recommendations.
