Do anti-wrinkle injections for migraines really work? How effective are they? How do they work?

If the botulinum toxin is so poisonous, then how can you get anti-wrinkle injections without dying?

Do you have to stop LED for a while?

I’ve had countless doctors say that anti-wrinkle injections to the masseter will eventually become permanent, because the brain stops signalling one to use the treated muscle. If masseter muscles can be permanently affected by the injections, isn’t it likely upper cheek muscles around the eye can also be permanently affected? Why would the brain reprogram muscle use in the jaw and not in other parts of the face?

Can anti-wrinkle injections be used in areas other than crow’s feet and forehead wrinkles? What are other benefits?

At 30 years old I got my first treatment with anti-wrinkle injections between brows on Wed. I can see a small change in lines but I am hoping they will become less indented. When I frown it’s slightly restricted but the current results aren’t what I was expecting. I know full results take up to 14 days, but I was hoping for them to (if not) completely disappear – be very faint. Will they become fainter in the next few days since it’s only been 3 days since I got the treatment? Will they ever completely disappear?

Why does my treatment with anti-wrinkle injections only last 2 months? I use a very good doctor with a fantastic reputation in Ireland. However, my anti-wrinkle injection treatment only lasts around 2 months on my forehead. I do have a young face for a man in his 30s. Any ideas as to what biological process could be the reason and/or any way to get longer out of anti-wrinkle injections?
