Botox in the upper lip, can't smile normally, when will this go away?

I'm not sure when you had your treatment, but it can take 1-2 weeks for final results with Botox. Botox results resolve in 3-4 months. In the mean time, venus legacy treatments can soften results. Best, Dr. Emer

Thank you for your question. Typically, it does take 3-4 months for Botox  to wear completely off. However, you had a rather small dose and it may be less. There’s no way to know for sure. Perhaps, your injector can give you some advice. Good luck! Dr. Aldo

Thank you for your question. A side effect of Botox into the lip is that your lip can come over your teeth. This happens because the muscle in the upper lip has been relaxed. Unfortunately, this will take 3-4 months to wear off. I recommend having a follow up with your injector for an evaluation. Best of Luck!
