What should you know about dark skin under eyes?

The skin beneath the eyes is thin and can show colour from melanin or blood vessels more clearly than nearby skin. Rubbing, eczema-like inflammation, allergies, and repeated irritation can leave darker-looking skin. A hollow beneath the eye can also cast a shadow that resembles pigmentation. Uneven colour on both sides often has a different explanation from a new, one-sided change. Look for itching, scaling, watering, swelling, or a clear hollow when describing it to a clinician. More detail is available in Dark Circles and Atopic Dermatitis.

Use a gentle, fragrance-free cleanser and moisturiser, and avoid rubbing or applying strong bleaching products close to the eye. Manage triggers such as fragranced cosmetics if they sting or itch. Daily broad-spectrum sun protection can help prevent pigment from becoming more noticeable; sunglasses add physical protection outdoors. A dermatologist can distinguish pigment from shadowing and may discuss a carefully selected topical product or procedure. Under-eye filler is relevant only when a tear-trough hollow contributes to the appearance, and the risks around this delicate area need a specialist discussion.

Arrange a dermatology assessment if the colour change is new, one-sided, rapidly changing, associated with a persistent rash, or not improving after you stop irritation. Seek prompt care for painful swelling, marked redness, discharge, vision change, or an eye injury. A clinician can examine the eyelid skin and nearby structures rather than assuming every dark area is pigmentation.

Could this be pigment, irritation, a visible vessel pattern, or a tear-trough shadow? Should I stop any eye products? Which ingredients are safe near my eyelids? Would treatment risk further irritation or uneven colour?
