How Long Does Droopy Eyebrow Last After Having Dysport Side Effect?

Good news is that the effects of Dysport will wear off in about 3-4 months.  The drooping may resolve sooner than this. 

Luckily your eyebrow or eyelid droop will resolve when the Botox wears off. This can last several weeks to several months but will resolve completely. You can use several types of drops to elevate the eyelid if you're suffering from eyelid droop - these include apraclonidine, neosynephrine hydrochloride and brimonidine. These medication do have side effects so I would recommend discussing with your injector.Stephen Weber MD, FACS

Greetings~

Sorry to hear about your unfortunate Dysport experience.  When treating between the brows to address the vertical scowl lines, we are treating the muscles that run horizontally over the brow and when they contract create the vertical lines.  If instead of injecting those muscles part of the frontalis muscle (the muscles responsible for raising the eyebrows) is injected and weakened the brows can fall and flatten.  Though the effects of Dysport generally last 3-4 months, unwanted outcomes such as this generally resolve much sooner. (a few weeks)  The good news is, it will wear off. Hang in there.

Good luck~
