How Dark Circles Form Under the Eyes From Allergies

This pressure prevents the blood that supplies the superficial part of the face from draining back to the heart. This blood pools in the veins and capillaries underneath the eyes, causing a dark appearance, love a black eye.
Some of the fluid from inside the veins can slowly seep into the tissue under the eyes, leading to puffiness of the tissue as well.
How They Differ From Black Eyes
A black eye is a bruise caused by trauma. The blood seeps into the tissues from damaged blood vessels and the pigments are deposited in the tissues. This pigmentation from a black eye changes over the course of several days, often going from red to black to blue to green to yellow.
Allergic shiners do not own this blood seepage and so the appearance of dark circles should vanish once the nasal congestion is relieved and the blood flow can resume as normal.
Another difference is that dark circles from allergies generally appear under both eyes rather than just one eye, as is often the case with a black eye.
