How Soon After Having Botox Would a Ptosis Show Up? Hours? Days?

The periorbital eyelid muscle curves down at the tail of the eyebrow for most patients (some may shape their eyebrows differently and the true landmark of the bony orbit around the eye should be checked by the physician prior to injeciton). Botox in this depressor muscle of the eyebrow can help lift the eyebrow / eyelid complex. Usually one or two units is injected, for this off-label used of Botox. Drooping should not occur in this area. IF the technique was not the one mentioned above and a droop does occur, it can be seen even a week later but usually it starts a few days after the Botox.

Just because you had a small amount of BOTOX in the eyebrow does not mean that you will develop upper eyelid ptosis.  I routinely inject the eyebrows using Microdroplet BOTOX which does not cause upper eyelid ptosis.

Using Botox or Dysport to treat the lateral brow area for a subtle lift is a common and rewarding technique.  As with any injections in this area, technique and dosing are important to avoid an unintended outcome such as ptosis (drooping of the upper eyelid).  

If you were to experience an adverse outcome, you would be aware of this within a few days.  As other panel members suggested, a half unit dose will not offer any benefit for this technique.  In our practice, we generally use 5 units per side.
