Certain behaviours can lead to the appearance of dark circles under they eyes, such as not getting enough sleep, for example. But many people have dark circles even after having slept well. So how can we explain this?
1) Poor blood circulation
Given that the contours around the eyes are very sensitive, because the skin is so fine, this area is highly susceptible to changes in blood circulation. Permanent dark circles can be caused by blood circulation problems, and the circles may have dark blue or yellow tints.
2) Tiredness and lack of sleep
Most often, the appearance of dark circles is due to tiredness. The dark colour is caused by an accumulation of blood pigments under the skin. When we don’t get enough sleep, there is poor lymphatic circulation and pigment builds up. This is naturally eliminated after a good night’s sleep.
3) Stress or depression
If stress or worry is what prevents someone from sleeping well at night, or if they are prone to depression, it is once again the lack of reparatory sleep that leads to the appearance of dark circles. There are numerous natural methods for getting rid of stress, feeling happier or fighting against depression, especially in the field of alternative medicine.
4) Smoking or drinking alcohol
Smoking and/or drinking alcohol promotes the presence of dark circles under the eyes. Alcohol tends to also cause swelling and puffiness under the eyes.
5) Certain illnesses
More rarely, certain illnesses can explain the presence of dark circles (primarily diseases of the liver and gall bladder).
6) Hormonal changes
Certain hormonal changes such as during menstruation or the menopause can also cause dark circles to appear.
In relatively rare cases, allergies can lead to dark circles and bags under the eyes, which become red and swollen. Allergies can also sometimes cause itching.
