Dark circles occur under eyes due to a combination of reasons. It is noticeable under the eye, as people get older. As we age and receive more sun damage to our facial skin, the thin skin under the eye can become thinner and wrinkled, which allows the veins in the fat pad under the eye to become more prominent. As the skin here is slightly darker than the rest of your face, any changes in health show up immediately in this delicate area. Some people think that they occur because they are either tired, or as a result of sun exposure. This is not typically the case. Sometimes the dark spots can be hormonal, but often they are just hereditary.
Sometimes the dark spots are caused by the reflections or shadows cast by the bulges of fat that occur naturally in the lower eyelids as people get older. If the bulging of fat is the cause of the dark circles under the eyes, then cosmetic surgery to remove the fat bags is the only approach that is typically effective, other than concealer makeup. There are many contributing factors that make dark circles around the eyes more noticeable.
