Most people think that dark under-eye circles are caused by staying up late, having one too many drinks or illness. In most cases that’s true. Depending on the cause, dark circles under the eyes can arise suddenly and disappear quickly, such as when you have a mild allergic reaction to animal dander or dust. Dark circles under the eyes that develop over time may be a sign of chronic dehydration or anemia.
When an allergen hits the body, it releases histamine. This reaction makes blood vessels swell with blood and other fluids, which in turn causes the puffiness and darkness under the eyes; where skin is thinnest. Nasal congestion, sneezing, and watery, itchy eyes
Malnutrition, anemia and dehydration are more serious causes of dark circles. It is believed that a lack of iron can cause dark circles as well. Iron deficiency is the most common type of anemia and this condition is a sign that not enough oxygen is getting to the body tissues.
Dark circles are likely to become more noticeable and permanent with age. This is because as people get older, their skin loses collagen, becoming thinner and more translucent. Circles may also gradually begin to appear darker in one eye than the other as a result of some habitual facial expressions, such as an uneven smile.
