Botox worked immediately! Is it normal that it works this fast?

Yes I have seen it happen.  It is not often, but certain patients have immediate results like yourself.  Most patients we inject it does take a few days to perhaps up to 7 days before the muscle is paralyzed.Hope that helps.

It is unusual for Botox to work within a few hours, but not unheard of. Everybody reacts differently. As long as you are happy with your results, you shouldn't worry. The effects should last up to 3 to 4 months. Please consult a board-certified dermatologist for your Botox treatments.

The effects of Botox normally take 3 to 4 days. Considering the limited amount of Botox that you received for these 2 areas (15 units), you should be happy with your results!

Botox results can take up to 1-2 weeks, but this can happen. Keep in mind, Botox results last 3-4 months. Best, Dr. Emer

Dear happygirl20161367,
most patients complain that they don't see any difference after Botox injections. In your case it is different. You should be happy with your results and enjoy it. Daniel Barrett, MD, MHA, MS
