What should you know about periocular pigmentation?

The thin eyelid skin can show inherited pigment, sun-related dark patches, post-inflammatory colour change or underlying vessels. Rubbing from eczema, allergies, contact lenses or cosmetics may deepen the appearance. Hollowing and facial shadows can also resemble pigmentation. A clinician can examine the colour, texture and distribution rather than assuming every dark circle has the same cause. See [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) for broader context.

Use broad-spectrum sun protection around, but not in, the eyes, wear sunglasses, and avoid rubbing or untested lightening products near the eyelids. Stop a product that stings or causes swelling. Depending on the cause and skin tone, a dermatologist may discuss [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), IPL, picosecond laser or carefully selected topical treatment such as [Hydroquinone Treatment](/treatments/medical-dermatology/topical-hydroquinone-therapy/). Treatments near the eyes require specialist planning.

Seek prompt assessment for sudden one-sided darkening, eyelid swelling, pain, redness, vision change, a new changing spot or pigment affecting the eye itself. A rash, scaling or persistent itch may point to irritation or another condition that needs treatment.

Ask whether the colour is true pigment, shadow or visible vessels; whether allergies or rubbing are involved; and which products are safe near your eyes. Discuss sun protection, expected fading, irritation risk and how treatment will be adjusted for your skin tone.
