Eye 常見問題

黑眼圈

Common Causes of Dark Circles

• Vascular Dark Circles

◦ Poor Blood Circulation: Lack of sleep, excessive screen time, and other factors that disrupt blood circulation can cause blood vessels to dilate, resulting in a bluish hue under the eyes.
◦ Allergies: Allergies can lead to nasal congestion and poor blood circulation around the eyes, contributing to dark circles.

• Pigmentary Dark Circles

◦ Genetics: Some individuals are born with thinner skin under the eyes, making blood vessels more visible.
◦ Sun Exposure and Friction: Prolonged sun exposure and rubbing the eyes can lead to hyperpigmentation and dark circles.
◦ Dermatitis and Eczema: Inflammation of the skin around the eyes can cause pigmentation.

• Structural Dark Circles

◦ Orbital Hollowing: Congenital or age-related loss of orbital fat can create shadows under the eyes.
◦ Tear Troughs: Hollows between the lower eyelid and the cheek can deepen shadows and make dark circles more pronounced.
