I received my second dose of Botox for deep furrows from frowning, a year after my first dose. The dose did not take effect at all seven days later. The doctor stated that I may be a "super user" of the Botox, meaning that my body rejected the dose. He gave me an additional dose and it worked. Was this correct, and would I require more than the normal botox dose in the future?
I have no autoimmune diseases.
