Two possibilities exist:

1. Droopy eyebrow
2. Droopy eyelid

When injecting Botox along the eyebrows or between the brows, the Botox can migrate and affect the muscles of the eyelid. If this occurs, eyedrops can be used to help raise the affected eyelid. This usually resolves in 2-3 weeks, though it may last the entire time of the Botox, 3 months or more.

In patients who have their forehead injected, there is the possibility of eyebrow ptosis or droop. This occurs because of the unopposed action of the orbicularis oculi muscle. This produces a droop of the eyebrow which can last until the forehead muscle function returns.

Unfortunately, there is no way to reverse this droop.
