5 days after Botox and no improvement to elevens lines?

I would give it a full two weeks to determine whether the Botox will work. If there are issues at that time, contact your physician to address your concerns. They will be able to address any issues for you.

Botox timing until maximum effect is usually 10-14 days.  It is not abnormal for patients to have quicker responses sometimes compared to other times.  It is possible that the glabella (elevens) were not treated fully and may need to be touched up; give another week before deciding whether this is necessary.  Most of the time, there will be an additional cost if more product is needed, but these costs vary significantly from office to office.
