(NaturalNews) Dark circles under the eyes tend to give you an older, rather haggard or tired appearance. There are many factors that lead to the dark circles.
Why Dark Under Eye Circles Develop Age Typically, dark circles develop when the skin under the eyes become relatively thin and more transparent with age, write Dr David J. Goldberg M.D., a New Jersey dermatologist, and Eva M. Herriot in Secrets Of Great Skin: The Definitive Guide To Anti-aging Skin Care.
Allergies and Nasal Congestion Dark circles under the eyes are also caused by allergies such as asthma and hay fever, which tend to lead to congestion of the fine veins under the eyes. The Mayo Clinic also lists nasal congestion as one of the most common causes of dark circles. In an online article, the Clinic explains that when the nose gets congested, it causes veins that drain from the eyes into the nose to dilate and get darker.
Heredity Age and family traits play an important role in the appearance of dark circles. According to Linda Allen Schoen and Paul Lazar, hereditary anatomical factors are often a direct cause of under eye circles. In their book "The look you like: medical answers to 400 questions on skin and hair care," they explain that these circles particularly affect people who have thin, lower eyelid skins because the flow of blood in the veins beneath the surface tends to show through the skin, giving it a bluish-black tint.
Lack of Sleep Although people usually associate dark circles under the eye with lack of sleep, insomnia is not really a major cause, though it may aggravate the under eye circles. If lack of sleep does not cause dark circles, what is the relationship between them? Why do some people develop the circles when they are fatigued? According to authors Marianne Legato and Carol Colman, the skin below the eyes may lose some moisture and elasticity when one is exhausted, which will change the way light is reflected off the skin.
Shadowing Dark circles under the eyes may be little more than shadows cast by puffy under-eye bags. In their book "What Women Need to Know," Marianne Legato and Carol Colman state that dark circles may be an optical illusion that results from the way light gets reflected off the skin beneath the eyes.
Hormonal Changes In some instances, pregnancy and birth control pills may also cause the dark circles to develop. This is as a result of hormonal changes and increased pigmentation under the eyes respectively.
