It was not a factory-style clinic, but during the consultation I only spoke with the manager, and the doctor came in only for the procedure. The doctor briefly checked my jaw muscles and said they would inject based on similar muscle volume. Honestly, it did not seem like they looked that closely... I felt disappointed because, both outwardly and in my own mind, I was sure my jaw was asymmetric.
I already had somewhat prominent side cheekbones, so after the procedure my peanut-shaped face became even more pronounced.
