Under-Eye Dark Circles: Pigmentation, Vascularity, or Shadowing?

Brownish under-eye darkness may be due to increased melanin, genetic pigmentation, sun exposure, or pigmentation following chronic irritation.

Frequent rubbing of the eyes, especially in people with allergies or eczema, can further worsen pigmentation.

The skin around the eyes is extremely thin. This can make underlying blood vessels more visible, giving the area a bluish, purple, or reddish appearance.

This is different from brown pigmentation and may require a different treatment approach.

Sometimes, the skin isn't actually darker. Instead, the hollow beneath the eyes creates a shadow.

Changes in facial volume and the tear-trough contour can make this shadow more prominent, particularly with age.

In such cases, treating pigmentation alone may provide limited improvement.

As the skin becomes thinner and collagen and soft-tissue support change with age, underlying structures may become more visible, contributing to a tired or darker appearance.

Allergies, eczema, and irritation can lead to repeated eye rubbing. Chronic inflammation and mechanical irritation can then contribute to persistent pigmentation.

• Colour: Brown may suggest pigmentation, while blue or purple may indicate visible blood vessels.

• Lighting and facial contours: Changes with lighting or shadows may indicate a structural component.

• Skin thickness and texture

• Presence of under-eye hollowness

• History of allergies, eczema, or frequent eye rubbing

And often, there isn't just one cause.

Pigmentation, vascular visibility, and structural shadowing can coexist in the same person.

Treatment should depend on the underlying cause.

• Pigmentation may benefit from carefully selected topical treatments, photoprotection, and, in appropriate patients, procedures such as peels or lasers.

• Vascular components may require a different treatment approach.

• Structural hollowing or shadowing cannot be completely corrected with a pigmentation cream.

• When allergies or chronic rubbing are contributing factors, addressing the underlying trigger is an important part of treatment.

• The goal is not simply to make the under-eye area lighter. It is to understand why it appears dark in the first place.

The delicate under-eye area should not be overlooked when applying sunscreen.

Broad-spectrum photoprotection, along with sunglasses and other forms of physical protection, can help prevent worsening pigmentation and photoaging.

For pigmentation-prone skin, consistent sun protection is an essential part of treatment, not an optional add-on.

At our clinic, we don't treat every dark circle as pigmentation. We first assess the underlying cause, whether it is pigmentation, vascularity, thin skin, structural shadowing, or a combination of factors, and then tailor the treatment accordingly.

Because the right diagnosis is the first step toward the right treatment.
