Botox Drooping Eyebrow Permanent?

The good news is your symptoms are likely temporary and WILL improve. Facial exercises and other similar activities will not significantly help -- only time will...A drooping eye-BROW may happen in the following scenarios:(1) When the brow-elevating muscle in the forehead, the Frontalis, receives too high a dose of Botox.(2) The Botox is sub-optimally placed too low in the forehead; it should typically be placed at least 1 cm above the Brow. (3) It may also happen if you have a low set eyebrow to begin with, in which case any Botox to the Frontalis increases the likelihood of a brow droop. Ironically, as mentioned above, a droopy eye-BROW from Botox can sometimes be improved with MORE Botox -- this time, the Botox is typically injected into the outside (top of the crow's feet) part of the eye (aka the lateral aspect of the Orbicularis Oculi muscle) to generate a bit of a brow lift in that area -- by injecting more Botox and paralyzing the orbicularis muscle that normally acts to depress the brow in that area, you may get a slight compensatory brow lift (and even possibly restore some of your natural eyebrow arch)...If the extra Botox does not improve the brow droop, it will likely last as long as the full duration of the Botox -- 3-4 months.When it comes to Botox, I would recommend seeking, at the very least, the services of an experienced physician injector. I think the key with Botox lies in truly understanding the anatomy of the injected area, and more importantly the variability in the anatomy between patients -- for brows, the forehead, and anywhere else you plan on receiving a Botox injection. This includes having a firm understanding of the origin, insertion, and action of each muscle that will be injected, the thickness of each muscle targeted, how deep beneath the skin the actual muscle resides, and the patient variability therein. So, what kind of physician should be injecting your Botox? As an Aesthetic-trained Plastic Surgeon, I am intrinsically biased since I operate in the area for browlifts and facelifts, and have a unique perspective to the muscle anatomy as I commonly dissect under the skin, see the actual muscles themselves, and learn "first-hand" the incredible variability between patients -- live, "on the OR table" -- as opposed to via lectures or a cadaver dissection. For me, this helps guide where to inject and where not to. However, with that said, I know many non-aesthetic trained plastic surgeons and other physicians who know the anatomy well despite not operating in that area, and get good results.Good luck.Dr Markarian

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.

Botox lasts for 3 months on average, and sometimes longer depending on the patient. Botox is not permanent, and any associated side effects should wear off when the Botox does. To help improve the ptosis, apraclonidine eye drops can be used. Apraclonidine is an alpha-andrenergic agonist eye drop. It can cause the muscles to contract, elevating the upper lid. I would recommend speaking with your provider about this option. If necessary, you may also speak with a board certified opthamologist or oculoplastic surgeon. I hope this helps, and I wish you the best of luck.
