White eyeliner, just in the corner of the eye. I usually just line the inner 1/4 inch, top and bottom, and smudge it, then apply mascara and/or other liner as planned. It opens up the eye, makes you look awake and well rested... I like the MAC white liner. All the Hollywood girls use it! I guess. I don't know. Anyway, I use it.
(This isn't me)
So the new rules for how to be gorgeous:
1. Lots of water.
2. Lots of sleep.
3. A little white eyeliner.
