4. Lack of Sleep
One of the most common causes of dark circles appearing under the eyes is simple exhaustion. Dark circles under the eyes are a pretty common thing if you have been up all night studying, partying or working – even insomniacs will eventually start to show signs of having gotten too little sleep.
It’s recommended that you get at least eight hours of decent quality sleep per night; this is a rough guideline for just how much sleep you should get, and for some people, it’s a little more or a little less: Yes, there is a cross-section of the population who can get only a few hours sleep per night and feel fine the next day, but that’s simply not true for the most of us.
If lack of sleep is the reason for dark circles under your eyes, you could benefit from some rejuvenating caffeine cream, cucumber slices applied for ten to twenty minutes, or rinsing your face with icy cold water.
