Even without staying up late, you still have dark circles under your eyes. It turns out that these factors are causing the problem.

Many people think that dark circles are caused only by staying up late and lack of sleep. However, they do not know that dark circles may also occur when there are symptoms such as eczema around the eyes, allergies, irritation from cosmetics, deep tear troughs, and insufficient sun protection.

1. Genetic factors

Family heredity is an important factor that causes dark circles.

2. Eczema around eyes

Eczema itself does not cause eye pigmentation. However, if you keep scratching because of unbearable itching around your eyes, it will promote the formation of dark circles.

Continuous scratching and rubbing of the skin around the eyes can cause local swelling, inflammation, broken capillaries, and make the skin around the eyes look scarred and dull, forming dark circles.

3. Allergic factors

When an allergy occurs, the body's cells release the allergic mediator histamine, which increases the permeability of the body's capillaries and causes blood vessel dilation and swelling.

The skin on the eyelids and under the eyes is the thinnest skin tissue on the human body. When the blood vessels in these areas swell, their color will be darker and duller than the skin on other parts of the face, which is one of the reasons for the formation of dark circles.

The most effective way to deal with this kind of dark circles is to treat allergies. Dark circles will naturally disappear after the swelling of the blood vessels subsides.

4. Cosmetic irritation

Many cosmetics on the market now have the effect of covering or lightening dark circles, such as liquid foundation, concealer, etc.

It should be noted that, depending on individual circumstances, some cosmetics (such as mascara, eye shadow, concealer, etc.) may irritate the skin, induce allergies, or even aggravate dark circles.

If you experience stinging or itching on your skin after using cosmetics, stop using them and try not to scratch your face repeatedly, especially around your eyes.

5. Deep tear grooves

The tear trough starts from the inner corner of the eye and appears as a groove on the lower eyelid near the nose. It is formed by the atrophy and sagging of the soft tissue at the lower edge of the orbital septum.

People with thinner skin around their eyes will have more pronounced tear troughs. The tear trough on the inner side of the lower eyelid will become more obvious as you age.

However, tear troughs can create indentations under your eyes and make your skin look dull, leaving you with dark circles.

You can cover it up with a high-quality concealer, but make sure it won't irritate your skin or cause allergies.

6. Insufficient sun protection

The skin under the eyes is very delicate. Once sunburned, the blood vessels under the eyelids will expand rapidly, blood flow will accelerate, causing the skin to swell and the color to darken.
