It's a frequent misconception that dark circles are solely due to a lack of sleep. However, there are a number of other factors that might cause dark circles. Dark circles can be created by actual pigmentation of the skin around our eyes, which can occur for a variety of causes. So, aside from a lack of sleep, here are three other causes of dark circles:

AGING

Dark rings are most commonly caused by aging. When you start to get older, your skin sags and loosens, and it even thins out, making it appear darker than usual.

PUFFINESS

"We have a tissue that holds all of that back and, for genetic reasons, sometimes contacts lens wearers or really allergic people who rub their eyes a lot, that tissue becomes attenuated and thinner," stated Dr. Maryam Zamani, an oculoplastic surgeon in London who treats a variety of eye issues. As it becomes thinner and attenuated, the fat begins to protrude, causing genuine puffiness.

DEHYDRATION

When you drink, you lose fluids and electrolytes, including the fluid beneath your eyes. As a result, your eyes appear hollower, and there is less tissue between your skin and the bone socket beneath your eyes.

When you have moisture sealed into your skin, it thickens in that location, making the dilated and tortuous veins beneath it less visible.
