What should you know about eye bags and dark circles?

An eye bag is usually a contour change: fluid may make the area puffy, or skin and fat may create a lasting bulge. A dark circle may come from pigment, thin skin showing underlying vessels, a hollow that casts a shadow, or rubbing from irritation. Itching, dryness, or a rash around the eyes can occur with [Atopic Dermatitis](/conditions/atopic-dermatitis/). [Tear Trough Hollows](/conditions/tear-trough-hollows/) may look darker because of shadow, while [Dark Circles](/symptoms/dark-circles/) describes the visible symptom rather than one single cause.

Notice whether colour changes with lighting, sleep, congestion, rubbing, or skin flare-ups. Use gentle cleansing, avoid rubbing, and protect the area from sun; treat eczema or allergy symptoms with advice suited to the eyelid skin. A clinician can decide whether the priority is skin care, a hollow, or fullness. [Under-Eye Filler](/treatments/injectables/tear-trough-filler/) may be discussed only when a suitable hollow contributes to the shadow. Avoid applying strong or irritating products close to the eyes without guidance.

Arrange assessment for a new persistent change, one-sided swelling or colour change, significant itch with rash, pain, discharge, or swelling that affects the eye opening. Seek urgent care for severe eye pain, reduced or double vision, rapidly worsening swelling, or symptoms after an eye-area procedure. These signs are not explained by ordinary cosmetic shadowing alone.

Is the darkness pigment, visible blood vessels, a shadow, or irritation? Ask which products are safe near the eyelids, whether allergies or eczema need treatment, and whether a proposed procedure addresses colour, contour, or both.
