Q: I have had Botox injected successfully twice. This time I went to someone else and the Botox didn’t take. What could cause this?
A: There are many reasons this could have happened. It’s possible that outdated Botox was used. After dilution Botox is good for 2 weeks only. Some doctors dilute Botox too much to try and treat more patients with one bottle. It’s also possible that the doctor missed the muscle and placed the Botox too deep, or that not enough was used.
