I have a snarl facial expression that I do not control and its basically stuck on my face. When other people look at me they think that I am looking at them in disgust and that I am smelling a foul odor. I tried juvederm which worked for two days then the expression came back. I also tried botox but the doctor injected most of it in my forehead and only a little in the problem area. He stated that facial muscles are interconnected and it will help the problem but i haven't seen any results. Help
