Crepey skin in upper outer eyelid skin

I think you have several options. One, maybe more skin could have been removed on the outer part of your eyelid during your blepharoplasty. Second, filler to the brow and / or temple may be the answer. Third, a laser resurfacing can definitely improve the quality of the eyelid skin. I prefer the erbium laser by Sciton. It can create amazing wrinkle reduction without the negative side effects of a CO2 laser.Andrew Campbell, M.D.Facial Rejuvenation SpecialistQuintessa Aesthetic Centers

I would need to see photographs or better yet an in person examination to give a proper answer. Very often the patient needs a vertical forehad lift. If one has a lateral brow lift it tends to make patients look evil. See a very experienced brow lift surgeon who can advise you about vertical brow lifting procedures,  endoscopic if you were hairline is low, ITF lift if your hairline is high. 

The problem is likely NOT your eyelid, but rather your EYEBROW.  The outer tale of the eyebrows fall, creating the effect you are noticing. You may benefit from lateral brow lift. See following link for more details and video on a special pretrichial technique done under local anesthesia.

Good question.  The area you mention is a concern for many people.  It is difficult to make recommendations without photos.  Having said that, there are various options you mentioned and some you did not mention.    Lastly there are surgical options that address this area.  

A photograph would be very helpful but ultimately there is no substitute for a personal consultation. There are many options including fillers and botox.  This can be very powerful non-surgical options.
