Botox and eyebrows lift. When will the botox wear off?
Typically Botox wears off in about 3-4 months and you should see a gradual return of muscle activity in the treated area. How long the product lasts will depend on the individual's muscle tone, area treated, and number of units used. Discuss your concerns with your injector prior to the next treatment.
Clinical Context
Brow position reflects a balance between the frontalis muscle, which lifts the brow, and the corrugator, procerus, and orbicularis oculi muscles, which pull it down. Botox weakens those downward-pulling muscles, letting the frontalis raise the brow more. As the effect wears off, those muscles gradually regain strength, so the brow eases back down over time rather than dropping suddenly.
