The distribution of blood vessels around the eyes is relatively dense, and the color of the blood can easily show through the thin skin around the eyes. If the blood circulation is not good, dark circles under the eyes will appear. However, there are various types of dark circles, and to overcome them, we should treat them according to their specific causes.
Cause of congenital dark circles: The skin is naturally fine and thin, so the color of the venous blood that shows through appears darker, forming dark circles from a visual perspective. This phenomenon also occurs in the armpits and neck.
