Why are my eyelids uneven, and what can I do about it? (Photo)

Many different situations can lead to uneven eyelids. Some of these can be treated non-surgically and conservatively, even using some very advanced injection techniques with filler or very precise placement of Botox. Some situations truly do require surgery to resolve. 
It is important that you seek a consultation with an eyelid expert to delineate the exact cause and treatment options.
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.

Your left upper eyelid is droopy (ptosis) which automatically causes the left eyebrow to raise in order to assist lifting the droopy eyelid.  The treatment would be left upper eyelid ptosis surgery.  Best to see an oculoplastic surgeon for examination and treatment.

Thank you for the question.We see this quite often in our practice and typically can be treated with a procedure called Upper Blepharoplasty. This typically takes me about 20 minutes and its performed with local anesthesia in our fully accredited surgery center.
