Lack of sleep
Too little or irregular sleep can be a cause of both the appearance of dark circles and eye bags. That’s because when we don't spend enough time in the land of nod we can wake up with paler skin which makes blood capillaries under the eyes more visible. And when we’re tired, blood circulation tends to slow and fluid builds up under our eyes, making our eye bags more pronounced and darker. So get a regular bedtime routine where you’re in bed well before midnight with all your gadgets turned off to avoid distractions.
