How can I correct my extremely uneven eyebrows? (photos)

Botox could improve the asymmetry of your brows in one of 2 ways:  slightly lowering the right brow, or slightly raising the left brow.  Treating the orbicularis muscle on the left will have the added effect of making your left eye appear slightly larger while raising your left brow. Consultation with an experienced injector would be best to determine the potential satisfaction from the treatment.

Thanks for your question regarding eyebrow
asymmetry. The type of brow asymmetry demonstrated in the photos is usually
correctible by an experienced Botox physician. Because you are young in the
photos I see, I doubt you would have problems that this might be a compensatory
asymmetry which, on correction, would result in ptosis. This is most commonly
seen in older individuals. 

I have excellent results with injecting a higher dose in the
depressors in the weaker side, and a lesser dose in the higher side, with a
tiny whisper in the forehead on the higher side.  Make sure your
practitioner does a careful muscular evaluation, because proper dosing depends
on exactly how the muscles move.

 I hope this helps!
 Good luck!

I'm not sure Botox is your best answer. Not everyone gets elevation of their brow with Botox and, if they do, it's usually not much. It's certainly worth a try though. Ultherapy would be another option that is non-surgical. We would double the treatment on the low brow in the hope of elevating it enough that the asymmetry is less obvious. A last option would be a surgical browlift. These can be performed endoscopically so the incisions are hidden in the hair and downtime is minimal.Andrew Campbell, M.D.Facial Plastic SpecialistQuintessa Aesthetic Centers
