Jen, have you tried Smashbox's Photo Finish primer? (the Light version?) It's meant for all over your face, but there's no reason you couldn't just concentrate it on your lids only. I'm wondering if it could be stronger than a primer just made for the eyelids alone. Maybe Sephora would give you a sample to try.

Also I came across this tidbit in an article I was reading today:

"In a Good Housekeeping Research Institute test, primer helped volunteers' makeup look better and hold up throughout the day (even after a sweltering stint in our 80-degree, high-humidity chamber); Smashbox Photo Finish Foundation Primer Light ($36, Sephora) proved to be the very best of the bunch."
