Lack of sleep
Beauty sleep is a real thing. The hours when you’re conked out are when your skin repairs and renews itself. If you’re depriving yourself of a good night’s rest, your complexion won’t be able to rehab itself efficiently, leading to less cell turnover and a dull complexion.
In fact, a study in the journal Sleep found that sleep deprivation affects facial features such as the eyes, mouth and skin, causing hanging eyelids, redder and more swollen eyes, and darker circles under the eyes.
