Who else has dark/stress rings under their eyes? If I'm correct this is caused by either lack of sleep or stress, both of which I have. My under eyes look kind of tighter than normal like they're sucked in. And have a dark shade to them with visible lines beneath my eyes that weren't there when I was younger. It's aesthetically ugly I guess, who wants to see a stressed out person? This is making me even more self conscious. ****tt! I noticed that many people with SA have these dark rings.
