What should you know about dark circles and sunken eyes?

Dark circles and sunken eyes often come from a mix of skin colour, shadows, irritation, lifestyle factors, and changes in under-eye volume. The appearance can be longstanding or become more noticeable with fatigue, dehydration, nasal allergies, rubbing, or facial changes over time. Looking at the colour, skin texture, and depth of the under-eye area helps separate darkness caused by pigment from darkness caused mainly by a hollow casting a shadow.

Thin under-eye skin can make small blood vessels and underlying tissue more visible. Some people naturally have more pigment in this area, while congestion from allergies can make shadows look stronger. Repeated rubbing may irritate the skin and deepen discolouration. A tear-trough hollow can create a boundary between the lower eyelid and cheek, so overhead light produces a darker-looking groove even when the skin itself is not very dark.

Eczema around the eyelids can bring itching, dryness, scaling, or colour change. These features point to a skin problem worth discussing, especially if skincare products sting or the rash keeps returning.

Avoid rubbing the eye area and use gentle, fragrance-free products if the skin is sensitive. Consistent sleep, hydration, allergy management, and daily sun protection may reduce factors that make the area look tired or more pigmented. Take note of whether the concern is mainly colour, puffiness, a hollow, or irritated skin; this gives a clinician a clearer starting point.

For a hollow that remains bothersome, a qualified clinician can assess whether under-eye filler is suitable. This is a precise area with important blood vessels, so the decision should include an examination of skin quality, puffiness, facial proportions, and treatment risks rather than a one-size-fits-all approach.

Arrange prompt medical assessment for a new dark area or swelling on one side, pain, redness, warmth, vision changes, fever, an injury around the eye, or a rapidly changing appearance. Seek care as well if eyelid itching, scaling, or swelling persists, because contact irritation, eczema, or another eye-area condition may need targeted treatment.

Ask whether your appearance is driven mainly by pigment, visible vessels, puffiness, skin inflammation, or a tear-trough hollow. Also ask which products are appropriate near your eyes, whether allergies or dermatitis could be contributing, and what the expected benefits and risks are for any procedure being considered.
