Dark Circles Reason: It is often believed that the main cause of dark circles under the eyes is lack of sleep or excessive fatigue. Over the years, our elders and popular beliefs have taught us that if you do not get enough rest, bags will form under your eyes.

Although health experts believe that lack of sleep is a common reason but it is not the only reason. The skin under the eyes is very delicate and there can be many hidden reasons behind the changes occurring here. To manage this condition effectively, it is important to understand its true causes.

Dark circles are genetics

One of the most common but often overlooked causes of dark circles is genetics. If your parents have had the problem of dark circles, then there is a strong possibility that you too may develop this problem. In such cases, the skin under the eyes is naturally thinner, which makes the blood vessels underneath more visible and the area appears darker.

Aging and skin changes

Aging is also a major factor in dark circles. As we age, the skin begins to lose its collagen and elasticity, causing the skin to become thinner. This results in the under eye area appearing sunken and shadowy which often causes dark circles and puffiness. Lack of fat and retention of fluids in the body can make this condition worse.

Allergies and habit of rubbing eyes

Various types of allergies such as allergic rhinitis can cause swelling and discoloration under the eyes. When we have allergies we often feel itching in the eyes and rub them again and again. The skin around the eyes is extremely delicate and rubbing it repeatedly can increase irritation and inflammation, making dark circles more visible.

Effect of dehydration and diet

Lack of water in the body i.e. dehydration is also a major culprit. When your body does not have enough fluids, the skin around the eyes begins to look lifeless and sunken. Apart from this, our eating habits also play an important role. Excessive amount of salt in food helps in retaining water in the body which leads to puffiness or swelling under the eyes.

Lifestyle and effect of sunlight

In today’s era, screen time has increased which puts pressure on the eyes and can cause pigmentation over time. Smoking and alcohol consumption also harm skin health, which increases the problem of premature aging and dark circles.

Besides this, spending too much time in the sun can also be dangerous as it increases the production of melanin which makes the skin around the eyes darker. Therefore, you can reduce this problem by drinking enough water, protection from sunlight and adopting the right lifestyle.
