Drooping Eyebrow After Botox

Dear Dermaqueen
It is my experience that the effects of BOTOX begin to be evident at 2 to 3 days but are not at their maximal effect until about three weeks after treatment. Then the effect is sustained for about 3 months and then begins to rapidly diminish. Unwanted side effects may not persist nearly this long because generally, these are typically caused by only a tiny fraction of the total treatment.
However, brow drop is a 100% predictable result of injecting BOTOX into the forehead. The muscle up there makes the forehead lines but also lifts and supports the eyebrows. The position of the eyebrow is determined by a tug of war between the brow elevators and the eyebrow depressors. I actually due a treatment I call MicrodropletTM BOTOX where I extensively only treat the eyebrow depressors. My technique allows me very precise control over the placement of the BOTOX. By just treating the eyebrow depressors and leaving the forehead lifter alone, a significant, naturally looking lift in the eyebrows results. I am applying for a patent for this method.
As your treatment sets in the asymmetry may or may not persist. Your doctor can adjust the asymmetry with a little more BOTOX in the forehead. The doctor is welcome to review my technique but should be careful of using it on you. The treatment method is often counter intuitive to doctors who are use to paralyzing things and are uncomfortable with using small doses of BOTOX to balance things.

Hi DQ.  A droopy brow is one of the side effects of Botox injections.  Although it does not happen often for experienced injectors, it can happen when the solution migrates from the muscle group that the drug is intended to relax to an adjacent muscle group.  With eyebrow droop, we can sometimes fix it if we relax the crows feet but it seems you had that done at a previous injection.  You should visit your injector for feedback, but you may have to wait 1-2 months for the area to improve. 

Eyebrow drooping after neuromodulators like Botox, Dysport or Xeomin is a rare but well described issue, usually resulting from product placement or the amount used. 
The first thing that needs to be determined is whether it is a droopy eyebrow or a droopy eyelid. Droopy eyebrows are much more common and result from over-immobilizing the only muscle on the forehead that is able to lift up our eyebrows - choosing the right amount and placement in the right patient is key to good forehead results. Droopy eyelids come from the product getting into the wrong muscle that elevates the eyelid. 
Management of them is quite different, but both have strategies to help expedite resolution while waiting for them to resolve with time, and any experience injector should be very familiar with how to deal with them: drops for the eyelids and precise placement of Botox in the brow depressors when it is an eyebrow issue. 
To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon.
