Periorbital dark circles (also known as dark circles, infraorbital venous stasis or periorbital hyperpigmentation) are dark blemishes around the eyes. There are many causes of this symptom, including heredity and bruising.
Allergies, asthma, and eczema
Any condition that causes the eyes to itch can contribute to darker circles due to rubbing or scratching the skin around them. Hay fever sufferers in particular will notice under-eye "smudges" during the height of the allergy season.
Any medications that cause blood vessels to dilate can cause circles under the eyes to darken. Because the skin under the eyes is very delicate, any increased blood flow shows through the skin.
The lack of nutrients in the diet, or the lack of a balanced diet, can contribute to the discoloration of the area under the eyes. It is believed that iron deficiency 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.
Periorbital hyperpigmentation is the official name for when there is more melanin produced around the eyes than is usual, giving them a darker color.

At one time, Hydroquinone solution was often mixed in an oil-free moisturizer that acted like a skin bleach. However the use of hydroquinone for skin whitening has been banned in European countries due to health concerns. In 2006, the United States Food and Drug Administration revoked its approval of hydroquinone for over the counter preparations warning that it may cause cancer or have many other detrimental effects.
The use of hydroquinone skin-whitening products can be toxic, harmful or lethal for humans.
Modern treatments include topical creams that are marketed for the condition (e.g. L'Oreal, Olay, Skin Doctors etc.). Various ingredients have been researched, developed and included in these creams. For example, recently, chemical compounds called alpha hydroxy acids (AHAs) have been added as a beneficial ingredient to creams for dark circles. Specialist treatments including laser and intense pulsed light skin surgery can also be used.
