Open your eyes by applying a light coat of mascara. However, make sure you use it sparingly as too much can get clumpy and your eyes will look heavier.
If you are expecting on only getting a few hours of sleep tonight, apply a little night cream under your eyes so it can work throughout the night and in the mornings, dab a little eye cream along any dark circles for instant de-puffiness.
Lack of sleep can leave you looking pale and withdrawn, so pop on a little blusher to give colour to your cheeks and make you look a little brighter.
Heavy, untidy eyebrows can make you look tired so make sure your brows are plucked and defined.
