Unfortunately, you are experiencing a rare but known complication after Botox -- eyelid droop. This happens when some of the Botox inadvertently diffuses to the muscle that normally elevates the eyelid. Since the complete effect of Botox is not seen for 7-10 days, in your case the eyelid droop may get a little worse before it gets better -- but rest assured, it WILL get better.The issue now is how long it will take and what you can do about it. You need to see an experienced physician injector who can examine you. You are likely a candidate for Apraclonidine eye-drops that may raise your eyelid approximately 2mm. But note that in some patients, you may not have any improvement at all and will have to wait for the effects of the Botox to wear off for the eyelid droop to improve. Since the complete dose of Botox is unlikely to have infiltrated onto your eyelid, the lid droop will likely improve in the next 1-2 months (and not the 3-4 months that Botox normally lasts). Rarely, if more Botox penetrated into the eyelid muscle, the lid droop may last longer... But again, the good news is that it IS reversible and NOT permanent.I would encourage you to seek the services of an experienced physician injector. I think the key 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, and the patient variability therein. 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 since I commonly dissect under the skin and see the actual muscles themselves. For me, this helps guide where to inject and where not to. However, with that said, I know many Dermatologists who know the anatomy well despite not operating in that area, and get great results.Good luck.
