Periorbital Hyperpigmentation
Periorbital Hyperpigmentation — darkening of the skin around the eyes, commonly referred to as dark circles, that gives the under-eye area a shadowed or discolored appearance. It can result from excess melanin, thin skin revealing underlying blood vessels, genetics, or factors like fatigue and allergies. Because the eye area skin is especially delicate, several causes often contribute at once.
Key points
- Contributing factors include hereditary pigmentation, visible vasculature beneath thin under-eye skin, and shadowing from facial structure.
- Lifestyle influences such as poor sleep, rubbing from allergies, and sun exposure can make the discoloration more noticeable.
- Gentle sun protection and ingredients like vitamin C, niacinamide, and caffeine are commonly used to support brighter-looking under-eyes.
- Because pigment, vascular, and structural causes differ, the most helpful approach depends on the underlying reason.
Frequently asked
Are dark circles always caused by lack of sleep?
No; while fatigue can worsen their appearance, dark circles often stem from genetics, pigmentation, thin skin, or visible blood vessels rather than sleep alone.
Can skincare fully remove periorbital hyperpigmentation?
Skincare can help brighten and even the area, but results vary by cause, and structural or vascular contributors may respond less to topical products.
