Dear Dr Lam,
I believe you are a specialist in this area and would really respect if you can answer my question. I have got botox on my jaw , however in my case the lower part of the jaw chin area is still very square.In fact that was the concerning area to start with. In my case has been injected exactly only on the jaw angle.There is a reduction of mass I see at that point.
However, there is a masseter muscle on clenching which I can feel on the lower jaw line towards the chin which was and is still contributing a lot to the squareness. Is this a safe site to have botox injected the next time?
Look forward to your reply.
