Why does periorbital hyperpigmentation cause dark circles?

Periorbital hyperpigmentation refers to increased colour around the eyelids or under-eye area. The skin there is thin and highly visible, so pigment changes can look like brown, grey, or deeper shadows. Genetics, repeated rubbing, irritation, sun exposure, and the natural shape of the eye socket can all influence how darkness appears. Dark Circles is a very common presentation of Periorbital Hyperpigmentation, although under-eye darkness can also have other contributors such as visible vessels or shadowing.

Avoid rubbing the eyes and treat itch or allergy symptoms with professional guidance. Use gentle, fragrance-free products and protect the area from sunlight without getting products into the eyes. A dermatologist can assess whether pigment, vessels, or shadows are dominant and discuss suitable options; the delicate eyelid area needs carefully selected treatment.

Arrange an assessment if the colour change is new, affects one side, follows persistent irritation, or comes with swelling, pain, scaling, or vision symptoms. Seek urgent care for sudden vision change, severe eye pain, or marked swelling. Do not use lightening products near the eyes unless a clinician confirms they are appropriate.

Is the darkness mainly pigment, visible vessels, or shadowing? Could rubbing or an eyelid condition be contributing? Which eye-area products and treatments are safe for my skin?
