Long lasting brow Ptosis after Botox, how much longer will it last?

The effects of Botox are temporary, typically lasting three to four months. If you are able to animate the brows freely then the product has worn off. I encourage you to visit with your injector to discuss your concerns.

It is improbable that there is any Botox effect after 12 months. Even muscle retraining fades over time. To get the most accurate opinion, it would be very helpful to have a full face photo of you looking straight ahead before your Botox treatment and a similar photo of the face now. I have seen the effects of upper eyelid ptosis last about 1 year after an unfortunate Botox injection but need to stress that this is very rare. In all likelihood, something other than brow ptosis from Botox is going on. Why did you get forehead Botox injections in the first place. Also are you using brow lash growth serum? This can damage the fat under the eyebrows and lead to brow atrophy.
