Heavy, Droopy Eyelids and Eyebrows After Botox

Botox causes paralysis of the underlying muscles with the intention of decreasing the wrinkling of the overlying skin. The underlying muscles are in balance and help to maintain facial expression - including brow position. When the support of the brow height is thrown off with Botox, then the brows may drop. The answer next time, if for less Botox directly above your brows which will leave enough support to keep the brows elevated. The "heavy lids" is likely due to the dropped brows compressing the skin of the lids between the lid margin and the brow. All of this will resolve as the Botox wares off. Good luck.

Medial brow ptosis or descent of the central brow can occur for several reasons:
-Botox placed too low within the frontalis muscle along the forehead including central forehead.  The frontalis muscle elevates the forehead and by decreasing activity here the central brow can drop
-Botox placed too superficially along the corrugator.  The botox will again impact the frontalis muscle and paradoxically lower the central brow.
Botox is best injected by an experienced injector to lessen wrinkles while improving facial appearance.

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.
