What can I do to correct my asymmetrical eyelids? (photos)

The asymmetry appears to be from left upper eyelid ptosis (droopy), which may benefit from ptosis surgery. That is very different from upper blepharoplasty which merely removes skin. Another idea which can camouflage (but not treat the underling cause for the asymmetry) could be filler injection in the left brow/eyelid.  See an oculoplastic surgeon.

You clearly have left upper eyelid ptosis.  However you most likely also have bilateral upper eyelid ptosis.  I say this because you are holding your eyebrows very high and the left upper eyebrow is even higher.  There basically two popular approaches to performing ptosis surgery.  In office testing will determine which of these surgeries would be appropriate for you.  The left upper eyelid has a second break in the upper eyelid fold.  I think this is also related to the ptosis.  I would recommend not removing any skin from the eyelid when the ptosis is corrected.  In many cases, when the tendon is advanced with surgery, this can sometimes bring the orbital fat forward filling the space behind the fold.  This may correct the second fold without sacrificing the upper eyelid fold which are needed to maintain a youthful appearance. Less is more.  If your potential surgeon spends less than 5 minutes with you, you are in the wrong office.  Look for a fellowship trained oculoplastic surgeon for this. 

I agree with several of my colleagues that you do appear to have a ptosis (droop) of your left upper eyelid. Simply removing skin from your upper eyelid will not fix this. Ptosis repair is performed surgically. If you do pursue surgery in Minnesota make sure that someone doesn't perform a blepharoplasty for you without addressing the eyelid droops. This won't improve the issue and can make the asymmetry appear more significant. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Best to obtain IN PERSON evaluations. Whether BOTOX alone or excision of skin, or fillers or a combination is hard to advise via the internet... 

You do have slanted eyelids, sometimes referred to as " oriental eyes" As young as you are, you do have excess skin which is more pronounced on the left side. Some skin resection, more on the left side and recreation of new supra tarsal fold ( line above your lashes ) may prove to be helpful. Very conservative levator muscle resection may be indicated. Cost for this operation is $ 4-6000.
