The skin around the eyes is particularly thin, allowing blood vessels to show through more prominently. This effect is more pronounced in young children than in adults and typically does not require further investigation.
In adults, pronounced dark circles often appear as a sign of dehydration (lack of fluid in the body) and fatigue.
In some cases, increased dark circles can result from inflammation or allergies. Children with atopic keratoconjunctivitis (AKC) typically develop dark, pigmented rings under their eyes, often accompanied by thickened or scaly skin. If your child has more pronounced dark circles, frequently rubs their eyes, or if there is a family history of allergies (such as eczema or pollen allergies) indicating a potential predisposition, an ophthalmological examination with a microscope is recommended.
