# Dark Circles

## Quick Summary

Dark circles are the visible look of darkness under the eyes. They can look brown, blue-purple, gray, shadowed, or mixed because the causes differ: uneven-looking pigment, visible vessels through thin skin, blood-pigment discoloration, puffiness that casts a shadow, or structural hollowing. Cosmetic skincare can help some tone, dullness, hydration, blue-purple discoloration, and temporary puffy-looking patterns, but it cannot correct every under-eye shadow.

## Causes

Brown-toned circles usually reflect uneven-looking pigment in the under-eye area. Sun exposure, rubbing, genetics, and irritation can make this pattern more noticeable. Niacinamide, vitamin C, careful SPF use, and irritation avoidance are the most relevant cosmetic tools for this pattern.

Blue-purple circles often appear when thin under-eye skin lets underlying vessels show through. Some formulas use Haloxyl for this vascular-looking subtype because its ingredient story centers on visible discoloration linked to blood pigment byproducts and iron-pigment appearance in the delicate under-eye area.

Fluid-related puffiness can cast a dark shadow under the lower lid. A structural hollow or tear trough can do the same even when the skin itself is healthy. Cosmetic skincare may soften the surface look, but deep hollowing and persistent swelling need a different conversation with a clinician.
