Periorbital hyperpigmentation, also known as hereditary dark circles, is characterized by darker skin around the eyes caused by the presence of additional melanin. It is an extremely common hereditary human characteristic and is frequently found on individuals with dark skin. Periorbital hyperpigmentation is most prevalent within the 16–25 ...
Lack of sleep, salty food, age, and genetics can cause puffy eyes. Here, dermatologists share causes, risk factors, treatment, and prevention for eye swelling.

[16] [17] Eye conjunctiva has a particularly high affinity for bilirubin deposition due to high elastin content. Slight increases in serum bilirubin can ...
These individuals may present with a unique set of physical characteristics such as xanthelasmas (yellow deposits of fat underneath the skin often presenting in the nasal portion of the eye), tendon and tuberous xanthomas, arcus juvenilis (the graying of the eye often characterized in older individuals), arterial bruits, claudication, and of ...
