After Botox injection, one eyebrow is higher than the other. Can it be fixed? (Photo)

Yes this can be fixed and you need to call your doctor who did the Botox and have them correct it. It should not be an issue and sometimes this happens. There is no need to wait the 6 months to fix this .

It would be helpful to see your before pictures and to know where you had your botox injections.  I agree that it looks like you may have a ptosis of the left eyelid and an elevation of your left eyebrow.  Ptosis occurs when the eyelid muscle does not elevate properly, and the forehead compensates by pulling the eyebrow (and eyelid) up.  You may have had a less exaggerated ptosis prior to your treatment, and the treatment may have exacerbated it. I think this issue can be treated/softened:1) weaken the obicularis on your right side (the obicularis pulls down on the eyebrow)2) weaken the forehead on your left side (the forehead elevates the
eyebrow) - must be very careful with this strategy, since it may make your lowered left eyelid even lower, which would be undesirable3) trial of brominidine drops on the left - this will help to elevate your left eyelid, but won't necessarily change the position of your browAlso, be reassured that all the effects will likely wear away in several weeks to months.
