Dark circles mainly arise near the eyes and are also known as 'bags under the eyes'. In some cases, darkness around the eyes is hereditary. Dark circles are also seen in people with allergies. There are other culprits - something you can do something about. Smoking, drinking a lot of coffee, soda or caffeine beverages will normally cause dark circles severe.

Dark circles are likely to become more noticeable and permanent with age. Excess folds of skin under the eyes will also make dark circles more pronounced. Common allergens include dairy and excessive sugar. Dark circles under the eyes are a sign that your liver or kidneys are carrying a toxic load. Too much sun can also cause under eye circles. A lack of sleep or excessive tiredness can cause paleness of the skin, which again allows the blood underneath the skin to become more visible and appear more blue or darker.

Causes:

1. Heredity: -

The dark circles are also caused due to heredity reasons. People with itchy skin conditions and prone to allergies, are highly suspected of dark circles due to inflammation and a lot of eye rubbing.

2. Lack of sleep: -

Those who suffer from insomnia, who do not get to sleep properly, and who overstress their muscles, are prone to dark circles.

3. Iron deficiency -

It is believed that lack of mineral 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.

Treatment:

Avoidance of the allergens is the best treatment, but this is often not possible. When it is not possible to avoid one or more allergens, there are two major forms of medical treatment: drugs and immunotherapy. Always read the package label for directions or consult your doctor or pharmacist before treating children with over-the-counter medications. Children are not small adults, but have different physiology. They are more susceptible than adults to the effects of certain medicines and may have unexpected reactions.
