Hay fever sufferers in particular will notice under-eye "smudges" during the height of the allergy season. Atopy can lead to frequent rubbing of the eyes, leading to local inflammation and increased pigmentation. [4] Also, dark circles from allergies are caused by superficial venous congestion [5] in the capillaries under the eyes.
A skin biopsy may be taken to determine capillaritis of dermal vessels. [8] Capillaritis or pigmented purpura is skin condition that has brown-reddish patches on the skin, which is caused by leaky capillaries. [9] Such skin biopsies are sent to a laboratory for a pathological examination, where each biopsy is observed under a microscope. [3]
