No matter how beautiful your makeup looked all day long, by the time you are ready to go to bed you should definitely call it a day for your face.

Not to mention that waking up with coon eyes is not the most attractive look in the world. When your average makeup remover helps clean up those last streaks of mascara or lipstick.
