Lack of sleep is not the only cause of skin discoloration under the eyes: some people suffer from lack of sleep and for some reason do not look tired.
Here are some other possible reasons why you have dark circles under your eyes:
If your parent has dark circles under their eyes, you most likely will or already have them. This phenomenon is associated with weak capillaries around the eyes.
Constant stress robs you of energy and contributes to sleep problems. This is when dark circles can appear. You can try some relaxation techniques and see if they help.
As you age, your skin becomes thinner and less elastic, and you lose fat and collagen, making the blood vessels around your eyes more visible.
Excess of melanin
Dark circles may be more noticeable in people with darker skin tones. Exposure to sunlight, which causes your body to produce melanin, can exacerbate dark circles if you have fair skin.
Dark circles under the eyes are a symptom of dehydration. Often the problem can be solved simply by drinking more fluids.
A diet low in protein and high in sugar can contribute to dark circles. Eating more high protein foods and limiting your intake of sugary foods can help solve this problem. Excessive alcohol consumption also leads to dark circles, so try to limit that as well.
Other causes of dark circles include allergies, allergic rhinitis, eczema, contact dermatitis, and rubbing or scratching of the eyes. If you are concerned about dark circles, consult a dermatologist – a specialist can help you determine the best way to get rid of the problem.
