Dark eye circles are a common concern, but the term describes an appearance rather than a single diagnosis. Pigmentation, visible blood vessels, structural shadowing, and thinning skin can all make the under-eye area look darker, and each requires a different approach.
Clinical literature describes periorbital hyperpigmentation as multifactorial, with genetic predisposition and a higher prevalence in darker skin phototypes.[1] Another way to understand dark eye circles is to consider what causes the darkness: increased skin pigmentation, visible blood vessels beneath the thin under-eye skin, or shadows created by hollowness and the natural contours around the eyes.[2]
The first step is therefore to identify which mechanisms are present and how much each one contributes. Treatment selection follows from that assessment.
Four mechanisms account for many presentations, although more than one may be present in the same patient.
True periorbital hyperpigmentation is caused by increased melanin in the thin skin around the eye. It often appears brown, remains visible under different lighting conditions, and moves with the skin when gently stretched.
It is more frequently reported in darker skin phototypes and may run in families. Sun exposure, eczema, allergic rubbing, post-inflammatory change, certain medicines, and medical conditions can also contribute. The literature describes it as a persistent concern that often improves gradually and may require more than one approach.[3]
The lower-eyelid skin is very thin, which can allow underlying vessels to show through as a blue, purple, or reddish tone. The appearance may become more noticeable with fatigue, poor sleep, nasal congestion, crying, or other factors that increase venous congestion.[2]
Vascular discolouration may fluctuate throughout the day or vary from one day to another, while true pigmentation generally remains more consistent over time.
Structural shadowing occurs when the tear trough or surrounding anatomy creates a concavity beneath the eye. Retaining-ligament anatomy, volume change, and the prominence of the orbital rim can all influence how light falls across this region.[2]
This type of darkness changes with lighting and head position. A shadow may become less visible when the light source is moved, or the chin is lifted, while pigment generally remains present because the colour is within the skin.
With age, the eyelid dermis becomes thinner and loses collagen. This can make underlying vessels and existing pigments more visible, so a similar degree of discolouration may appear more pronounced over time.
Volume deficiency and reduced skin quality frequently coexist. Combined approaches have been described because treating only one component may not fully address a mixed presentation.[3]
A few observations at home may provide useful clues, although they do not replace an in-person examination.
These simple checks may help you describe how the area behaves:
These checks are not diagnostic, but they can help patients understand why a consultation should assess the cause before recommending treatment.
Misdiagnosis is common because several different mechanisms can create a similar appearance. A treatment chosen based on appearance alone may therefore address only one part of the concern or may not be suitable at all.
The Singapore Medical Council notes that evidence in aesthetic practice may be limited or inconclusive and places particular emphasis on informed consent, including the discussion of relevant risks.[4] A careful consultation should therefore include examination, diagnosis, realistic outcomes and treatment limitations.
Broad-spectrum sun protection is an important foundation for pigment management. A randomised trial of daily sunscreen use demonstrated measurable prevention of skin ageing.[5] Topical care or carefully selected energy-based treatment may also be considered, but the thin periorbital skin requires a cautious approach.
No single treatment reliably resolves every case of periorbital pigmentation.[9] Improvement is often gradual, and recurrence can occur. In one comparison of three injectable approaches, recurrence at six months ranged from 30% to 60%, depending on the modality.[6] Expectations should therefore be individualised.
Vascular discolouration may improve when contributing factors such as poor sleep, allergic rhinitis, nasal congestion and eye rubbing are addressed. Cosmetic camouflage is also a reasonable option, particularly when the vessels are visible through naturally thin skin.
Filler does not remove visible vasculature. If it is placed too superficially, it may create or accentuate a bluish appearance.
Treatments directed at skin quality may gradually reduce translucency and improve fine textural changes. Where skin thinning and volume deficiency coexist, a combined plan may be considered following assessment.[3]
These changes are progressive and cumulative. They are generally assessed over weeks to months rather than immediately after treatment.
Some dark circles are largely constitutional. Deep-set eyes, prominent orbital rims, naturally thin skin and family traits can create an under-eye appearance that is part of normal facial anatomy rather than a medical problem.
In these cases, aggressive treatment may not provide a natural or worthwhile improvement. Photoprotection, adequate sleep, management of rubbing or allergies, camouflage, and reassurance may form part or all of the appropriate plan.
The most important part of a dark-circle consultation is identifying which of the four mechanisms is present and how each contributes to the patient’s concern.
At VIDASKIN, the assessment comes before treatment selection. Depending on the cause, the plan may involve pigment management, carefully selected volume restoration, skin-quality treatment, management of a contributing medical condition, or reassurance that the appearance reflects normal anatomy.

Poor sleep can make vascular congestion or fluid retention more noticeable, which is why some dark circles appear worse when a patient is tired. It does not directly cause pigmentation or structural shadowing, so the benefit of improving sleep depends on the underlying mechanism.[2]
Complete and permanent removal is not always realistic. Structural shadowing may improve when volume loss is the main driver, while pigmentary change can be persistent and may recur. One comparison of injectable approaches reported recurrence in 30% to 60% of cases at six months.[3][6]
Filler may help when the darkness is primarily caused by structural shadowing from a contour deficit. It does not treat pigment or remove visible blood vessels, and superficial placement can worsen discolouration. Assessment is therefore important before treatment.[7]
Lighting can change the appearance of a structural shadow. Light from above may deepen the tear-trough shadow, while light from below can soften it. Pigmentation tends to remain more consistent under different lighting conditions.
Periorbital hyperpigmentation is reported more frequently in darker skin phototypes, and genetic predisposition is an important contributor.[1] However, pigmentation is only one possible cause, so individual assessment remains necessary.
