What Causes Dark Circles Under the Eyes in Women?

The under-eye skin is delicate, so blood vessels and underlying shadows may show through more easily. Brown or grey colour can relate to pigmentation, sun exposure, rubbing, or a past rash. A hollow near the inner lower eyelid can cast a shadow; this is known as [Tear Trough Hollows](/conditions/tear-trough-hollows/). Eczema or allergy-related rubbing may leave darker skin, and [Atopic Dermatitis](/conditions/atopic-dermatitis/) can affect the eyelid area. Sleep disruption and dehydration may make existing shadows look more noticeable, but dark circles are not a reliable sign of a specific illness.

Use gentle, fragrance-free products around the eyes, avoid rubbing, and apply broad-spectrum sun protection without getting it into the eyes. Treating itch or dermatitis can reduce rubbing-related colour change. A dermatologist can distinguish pigment from vascular colour and shadowing, then discuss options such as topical care or [Under-Eye Filler](/treatments/injectables/tear-trough-filler/) when hollowness is the main contributor. Filler is not suitable for every person or every type of dark circle.

Seek medical advice if darkness appears suddenly, affects one side, follows swelling, or comes with pain, marked redness, vision change, discharge, or a persistent rash. Arrange an assessment if the skin is repeatedly itchy or swollen, because treating the underlying irritation may matter more than lightening the colour. Bring a list of eye products and medicines if the change began after using something new.

Is the colour mainly pigment, visible vessels, or a shadow from hollowness? Could eczema or rubbing be contributing, and which eye-area products are appropriate for me?
