LOL...okay, I'll add on so you're not the thread killer... I remember hearing about the Prep. H thing on an episode of Everybody Loves Raymond. I have both the bags AND the darkness. Part of it's just heredity, at least in my case (thanks Mom!). I have found that Anew Force Extra eye cream works fairly well for me. It seems to lighten the area a bit and smooth the area out just a little... Sometimes I fool with it, sometimes I don't...
ETA: Moving south and wearing sunglasses sounds like a better solution!
