Did the Doctor Inject Too Much Botox?

Hi YNY,
Botox generally takes about 1 week to take full effect.You would not know immediately after injection if your practitioner has injected too much, but generally at 5 days after you would.
Do you have any side effects like eyelid or brow drooping? If you feel that something about the appearance leads you to believe that you have had too much Botox injected then you should get back in touch with your practitioner (probably about 2 weeks after the initial injections) to go over your results.

Botox does not generally take effect immediately. However, it is possible that your physician mixed it with a local anesthetic which will immediately relax the muscle.
Another explanation has already been given regarding swelling and distention of the injected area. Although the package insert states and most physicians state that the effect takes 3-5 days to work, I have had many patients who claim that it is effective within the first 24 hours. Clearly this is a common observation.

Botox does not work immediately. The change that you see immediately is from swelling, not the Botox. Botox generally starts working at 3 to 7 days. However, I have seen it start working after 1 day as well, but this is very unusual. As long as your final results after two weeks are nice, then there is no issue with the amount of Botox. Good luck.
