Dr. Sebagh - Supreme Night Secret - 50 ml. This stuff is so stupidly expensive, but the sales associates @ Barneys in Chicago were not lying when they said it "makes you look like you slept 8 hours, even if you only slept 4". So, on those rare occasions that I am severely sleep-deprived (FOUR hours?!), I will look fantastic, even if I sound like a blubbering idiot. Yeah!
