Onset of Botox can take several days

Most patients start to see the results of Botox in the first few days after  the injection but the peak onset could take as much as two weeks. By the third day most have some relaxation.

I usually tell my patients that they will see a result from Botox anywhere from 2-7 days after my injection. Usually it is within 3 days.
