Your rough night needn't show on your face. This easy-to-apply serum has you covered—it uses the cooling effects of aloe vera and the pressure of the rollerball applicator to perk you up and improve circulation, while caffeine gets to work lessening pesky dark circles and puffiness. Use it in the morning, after lunch, or before a meeting to look exceptionally awake and alert—even if you're barely hanging in there.
