What are the causes of dark circles?

There should be no one who is not familiar with dark circles, right? "Isn't it just 'panda eyes'?" Do you know what are the causes of dark circles? If you only know that it’s caused by lack of sleep, then you’re out.

Detailed explanation of the causes of dark circles

1. Congenital or acquired increase in eyelid pigmentation; the patient's orbicularis oculi muscle is congenitally thicker, or the pigment of the eye skin is congenitally darker and more abundant than the skin pigmentation of adjacent parts, so the eyes appear dark gray.

2. Aging eyelids become loose and the skin wrinkles together, causing the skin tone to darken.

3. Eye bags appear and cause shadows.

4. The depression on the inner and lower side of the eye socket forms a tear trough and then a shadow.

5. Stagnation of blood in the eyelid veins causes the skin and eyes to darken.

6. Penetration of cosmetic pigment particles: For those who often use cosmetics, some dark cosmetic particles may penetrate into the eyelids. Over time, dark circles will appear.
