Key Takeaways

• Dark circles under the eyes have three distinct causes – pigmentation, vascular visibility, and structural (volume loss or hollowing) – and each requires a different treatment approach.
• Misidentifying the type of dark circle you have leads to treatments that do not work, which is why diagnosis before treatment matters.
• Pigmented dark circles are caused by excess melanin in the skin and are especially common in Malaysian patients with medium to darker skin tones.
• Vascular dark circles occur when blood vessels beneath the thin under-eye skin are visually prominent, creating a bluish or pinkish hue.
• Structural dark circles are caused by volume loss or hollowing in the tear trough area, creating a shadow effect rather than true skin discolouration.
• Most patients have a combination of more than one type, which requires a layered treatment strategy.

Why “Dark Circles” Is Not One Diagnosis

Ask most people what causes dark circles under the eyes and they will say tiredness, genetics, or not drinking enough water. These are not wrong – but they are incomplete. Dark circles are a symptom, not a condition, and they can arise from fundamentally different biological mechanisms that look superficially similar in the mirror.

This matters practically: if your dark circles are primarily structural (caused by hollowing under the eye), no amount of vitamin C serum or brightening cream will make a meaningful difference – because there is no pigmentation to brighten. If your circles are primarily pigmented, under-eye filler will not address the underlying discolouration.

Type 1: Pigmented Dark Circles

Pigmented dark circles are caused by excess melanin – the skin’s pigment – in the skin beneath the eye. This is the most common type among Asian patients, including Malaysians, because of the naturally higher melanocyte activity in medium to darker skin tones and the skin’s tendency to produce pigment in response to inflammation, sun exposure, or friction.

What Causes Them:

Genetic hyperpigmentation. Many Malaysians have a family history of periorbital darkening that began in childhood or early adulthood. This reflects a hereditary tendency for melanocytes in the under-eye area to produce excess pigment.

Post-inflammatory hyperpigmentation. Rubbing the eyes – whether from allergies, irritation, or habit – creates micro-trauma to the delicate under-eye skin, triggering melanin production as a protective response. Allergic rhinitis and atopic dermatitis, both prevalent in Malaysia, are common contributing factors.

Sun exposure. The under-eye area is often neglected during sunscreen application, leaving it exposed to UV radiation that progressively stimulates melanin production.

How to Identify Them: Pigmented dark circles appear brown or dark brown. A useful self-test: stretch the under-eye skin gently with your finger – if the discolouration remains clearly visible and does not change significantly with the stretching, it is likely pigmented.

Type 2: Vascular Dark Circles

Vascular dark circles occur when blood vessels beneath the under-eye skin are visually apparent through the overlying tissue. The under-eye skin is among the thinnest anywhere on the body – sometimes as little as 0.5mm – which makes the underlying vascular network visible in a way it would not be on thicker skin.

How to Identify Them: Vascular dark circles tend to appear bluish or pinkish (rather than brown). They are often worse in the morning after lying flat and may improve slightly through the day. A useful test: press gently on the under-eye area – if the dark colour blanches (lightens) and then returns, it is likely vascular.

Treatment Approaches:

• Lifestyle measures: Adequate sleep, elevating the head during sleep, reducing alcohol and sodium intake, and managing allergies can reduce vascular congestion.
• Under-eye filler (small volumes): Adding a small amount of hyaluronic acid filler beneath the under-eye skin can thicken the tissue and physically mask the underlying vessels.
• Laser and light treatments: Certain vascular-targeting laser wavelengths can reduce the visibility of the underlying blood vessels.
• Retinoids: Topical retinoids stimulate collagen production and thicken the skin over time, reducing vascular visibility.

Type 3: Structural Dark Circles (Tear Trough and Volume Loss)

Structural dark circles are not caused by pigmentation or vascular visibility at all. They are caused by volume loss and anatomical changes in the periorbital region that create a shadow effect – giving the appearance of dark circles even when the skin itself has no discolouration.

How to Identify Them: Structural dark circles appear as a three-dimensional shadow rather than a flat brown or blue discolouration. They tend to be worse in harsh side-lighting. The simple stretch test is useful: if stretching the skin makes the “darkness” disappear, it is structural (a shadow) rather than pigmented.

Treatment Approaches:

• Under-eye filler (tear trough filler): Carefully placed hyaluronic acid filler in the tear trough and under-eye area is the gold standard treatment for structural dark circles.
• Mid-face volume restoration: Addressing volume loss in the cheeks simultaneously can produce a more comprehensive and natural-looking result.
• Surgical options: For patients with significant orbital fat prolapse or skin laxity, surgical evaluation (lower blepharoplasty) may be appropriate.

Most Patients Have a Combination

In clinical practice, purely pigmented, purely vascular, or purely structural dark circles are the exception rather than the rule. Most patients present with a combination – perhaps predominantly pigmented with a structural component, or vascular circles that have become more pronounced due to volume loss with age.

This is why the treatment approach for dark circles in a medical aesthetic setting is rarely a single intervention. A comprehensive plan might combine topical brightening agents (for the pigment component), tear trough filler (for the structural component), and lifestyle or laser interventions (for the vascular component).

Patient Experiences

Wei Ling, 34, TTDI

“I had been using various eye creams for years with no real change. During the consultation the doctor assessed my dark circles under different lighting conditions and identified that the primary issue was structural – the hollowing was creating a shadow rather than actual pigmentation. A small amount of tear trough filler produced an immediate visible difference.”

Preethi, 28, Puchong

“I have dark Indian skin and have had periorbital pigmentation since my teens. The doctor confirmed the pigmented type and explained that laser treatment would carry a higher risk of rebound pigmentation for my skin tone. We went with a combination of topical brightening agents and a gentle mandelic acid peel approach. The improvement has been gradual but steady over four months.”

Jason, 41, Bangsar

“I had attributed my dark circles entirely to sleep. The assessment showed a combination of three things

– some pigmentation, some hollowing from volume loss with age, and thinning skin that made the vessels more visible. The doctor put together a plan that addressed each component separately and we have been working through it over several months.”

Frequently Asked Questions

Can dark circles be completely cured?

This depends on the type and its severity. Structural dark circles can be corrected very effectively with filler, with results lasting 12 to 18 months or more. Pigmented dark circles can be significantly reduced but may require ongoing maintenance. Most patients achieve a meaningful improvement rather than a complete permanent cure.

Are under-eye fillers safe?

When performed by an experienced doctor with a detailed understanding of periorbital anatomy, under-eye filler has a good safety record. The under-eye area is anatomically complex and contains important blood vessels; the procedure should only be performed by a qualified doctor. Complications from incorrectly placed filler are rare in experienced hands.

Why do my dark circles look worse in the morning?

Morning worsening typically points to a vascular component – fluid and blood pool in the periorbital area during horizontal sleep and have not yet redistributed through the day. If your dark circles are consistently worse in the morning and improve through the day, prioritising vascular management in your treatment approach makes sense.

At what age do structural dark circles typically begin?

This varies significantly between individuals and is influenced by genetics as much as age. Some patients begin to notice tear trough hollowing in their late twenties or thirties, particularly if they have a naturally slender face or a family history of early facial volume loss. Others do not experience significant structural changes until their forties or beyond.

Do concealers make dark circles worse over time?

No – concealer does not worsen the underlying cause of dark circles. However, some patients tug at the delicate under-eye skin during application and removal, which can worsen pigmented dark circles by triggering post-inflammatory pigmentation from repeated micro-trauma. Gentle application and careful removal prevents this.
