The crescent-shaped areas under our eyes have a large concentration of tiny blood vessels. When a person is sleepy, tired or sick, the capillaries swell and become visible through the skin dark patches If you develop these bags under your eyes due to lack of sleep you can get rid of them temporarily by cooling the area with ice and reducing the swelling.
If you have these dark patches all the time whether you sleep well or not, it suggests that the pigment in that area is darker than in the rest of the face. In such cases you may have to consult a dermatologist if you want to get rid of the bags. The dermatologist can treat the problem with creams, chemical peels or other methods.
