Dark Circles Under Eyes: Causes, Treatments and Costs

Dark circles are dark discolourations or shadows under the eyes (periorbital hyperpigmentation) caused by pigmentation, visible blood vessels or volume loss. They can be treated with dermal fillers, laser therapy or skincare. Dark circles are among the most common aesthetic concerns that patients bring to cosmetic clinics. The dark shadows under the eyes make the face look tired, unwell or older – even when you are well-rested and healthy. They are not purely a cosmetic phenomenon: dark circles can have different medical causes, each requiring specific treatment approaches. Effective treatment requires first understanding which type is present – because the wrong treatment can be not only ineffective but may actually worsen the condition.

In this comprehensive guide, we explain the medical background of periorbital hyperpigmentation and shadows, present all modern treatment options, and provide a realistic overview of costs, risks and results.

What Are Dark Circles? Medical Definition

The term "dark circles" refers to various presentations in the periorbital area that manifest as dark discolouration, shadowing or hollowing under and around the eyes. Medically, this is termed periorbital hyperpigmentation (POH) or periorbital dark circles.

The periorbital region is one of the most delicate skin areas of the body. The skin here is only 0.5 to 2 mm thick, compared to 2 to 3 mm on other facial areas. This thinness makes underlying structures visible: blood vessels, muscle tissue and, with progressive volume loss, even bony structures. There is also a higher concentration of melanocytes (pigment-producing cells) and increased sensitivity to external factors such as UV radiation.

The development of dark circles is multifactorial. There is rarely a single cause; instead, it is usually a combination of genetic predisposition, anatomical features, lifestyle factors and ageing. This is why every serious treatment begins with a thorough diagnosis of the type present.

Causes of Dark Circles

Pigmentation

In pigmentation-related dark circles, increased melanin production in the periorbital area is the cause. Triggers include:

Genetic predisposition: Common in people with darker skin types (Fitzpatrick III–VI) and certain ethnic groups (South Asian, Arabic, Southern European descent). The predisposition is inherited in an autosomal dominant pattern.
UV exposure: Sunlight stimulates melanocytes. The thin periorbital skin is particularly susceptible to UV-induced pigmentation.
Chronic inflammation: Allergic reactions, atopic eczema, contact allergies or frequent eye rubbing can lead to post-inflammatory hyperpigmentation.
Hormonal changes: Pregnancy, oral contraceptives or thyroid disorders can stimulate melanin production in the face, including the periorbital area (melasma).
Medications: Certain drugs such as prostaglandin analogues (eye drops for glaucoma) or phenytoin can cause hyperpigmentation around the eyes.

Vascular Causes

Vascular dark circles are caused by the visibility of blood vessels through the thin periorbital skin. Contributing factors include:

Genetically thin, fair skin: The less subcutaneous tissue and the more transparent the epidermis, the more clearly visible the vessels.
Fatigue and sleep deprivation: Insufficient sleep causes blood vessels to dilate (vasodilation), intensifying the blue discolouration.
Allergies and respiratory conditions: Chronic allergies, sinusitis or upper respiratory tract conditions lead to venous congestion in the periorbital area ("allergic shiner").
Nicotine and alcohol consumption: Both substances impair microcirculation and promote vascular changes.
Dehydration: Fluid deficiency makes the skin appear thinner and more transparent.

Structural Causes and Volume Loss

With age, the structures of the face change fundamentally. In the periorbital area, these changes lead to characteristic hollows and depressions that cast shadows, perceived as dark circles. The central structure is the tear trough (nasojugal groove): a groove running from the inner corner of the eye downward and outward, formed by volume loss of periorbital fat and laxity of retaining ligaments.

Shadow from Swelling

Paradoxically, swelling can also cause dark circles – not through direct discolouration, but through the shadow cast by the bulging tissue on the area beneath it. This is particularly the case with protruding under-eye bags.

Types of Dark Circles

Type 1: Pigmented Dark Circles (Constitutional Type)

Pigmented dark circles are the most common form, appearing as brown, grey-brown or grey-blue discolouration. They are particularly prevalent in people with darker complexions and have a strong genetic component.

Treatment options: Laser treatment (Nd:YAG, fractional laser), IPL, bleaching creams with hydroquinone, azelaic acid, kojic acid, chemical peels.

Type 2: Vascular Dark Circles

Vascular dark circles are characterised by a bluish, violet or reddish discolouration caused by blood vessels visible through transparent skin. They can worsen with sleep deprivation and stress.

Treatment options: IPL, Nd:YAG laser (vascular treatment), carboxytherapy (improves microcirculation), topical agents such as vitamin K, retinol, caffeine.

Type 3: Structural Dark Circles (Shadow Type)

Structural dark circles arise from age-related or constitutional changes in the three-dimensional facial structure. The main feature is the tear trough, which casts shadows creating the appearance of dark circles.

Treatment options: Hyaluronic acid tear trough filler, polynucleotides, PRP, surgical blepharoplasty in severe cases.

Type 4: Mixed Dark Circles

In practice, the mixed type is most common: multiple causes contribute simultaneously. A combined treatment approach is required.

Diagnosis

Correct diagnosis is a prerequisite for effective treatment. In a specialist aesthetic practice, various examination methods are used to determine the type present:

Stretch test: The skin under the eye is gently stretched. If discolouration persists, pigmentation is present. If it fades, a vascular cause is more likely.
Light test: Tangential lighting helps identify structural shadows and volume loss.
Head tilt test: The patient tilts their head back. If the dark shadows disappear, they are structural in nature. If they persist, true pigmentation or a vascular cause is present.
Wood's lamp: UV light causes epidermal melanin to appear dark, enabling differentiation of superficial versus deep pigmentation.
Dermatoscopy: Allows assessment of vascular architecture and pigment distribution.

Treatment Methods Overview

Hyaluronic Acid Tear Trough Filler

Tear trough treatment with hyaluronic acid fillers is the most effective and most requested method for structural dark circles. By injecting specially formulated hyaluronic acid into the tear trough, missing volume is restored, the depression is filled and the shadow-casting effect is minimised.

Not every hyaluronic acid product is suitable for this sensitive area. Specially cross-linked, low-viscosity products are used that are less prone to water retention and deliver natural results in the thin tissue under the eye. Established products include Restylane Eyelight, Teosyal Redensity II and Juvederm Volbella.

Treatment procedure:

Consultation and diagnosis: thorough examination, type determination, discussion of expectations and risks.
Preparation: skin cleansing, application of topical anaesthetic cream.
Marking: precise marking of injection points according to individual anatomy.
Injection: very slow, small injections along the tear trough. Many specialists prefer cannulas (blunt needles) to sharp needles to reduce the risk of vessel injury.
Massage and modelling: the material is carefully modelled into the desired shape.
Result assessment: photo documentation and assessment of the outcome.

The effect of hyaluronic acid lasts 9–18 months depending on the product used and individual metabolism. The treatment is reversible: with hyaluronidase enzyme, the injected hyaluronic acid can be dissolved if results are unsatisfactory.

Laser Treatment and IPL

Laser procedures and IPL (Intense Pulsed Light) are the methods of choice for pigmented and vascular dark circles:

Nd:YAG laser (1064 nm): Suitable for vascular dark circles and deeper pigmentation. Also appropriate for darker skin types.
Q-switched Nd:YAG (532/1064 nm): For pigmentation treatment. Particularly effective for epidermal pigmentation.
Fractional CO2 and Er:YAG laser: Stimulate collagen production, improve skin quality and can increase skin opacity. Particularly useful when thin skin promotes vascular transparency.
IPL (Intense Pulsed Light): Broad-spectrum light that acts against both pigmentation and vascular changes. Best suited for lighter skin types.

Polynucleotides (PDRN)

Polynucleotides are biological agents derived from salmon DNA extract. They stimulate growth factors, improve skin hydration, promote new collagen synthesis and improve microcirculation. In the periorbital area, polynucleotides simultaneously address multiple causes of dark circles. A treatment series typically comprises 3–4 sessions at 2–4 week intervals.

PRP – Platelet Rich Plasma

PRP (also known as vampire lift) is an autologous procedure in which platelet-rich growth factors are extracted from the patient's own blood and injected into the tissue. In the periorbital area, PRP activates fibroblasts and stimulates the production of collagen and elastin, improving skin quality and reducing the transparency of the thin skin.

Carboxytherapy

In carboxytherapy, medical carbon dioxide (CO2) is injected into the subcutaneous tissue. The body responds with vasodilation and improved local blood flow, brightening vascular dark circles and stimulating collagen synthesis. A series of 6–10 sessions is recommended.

Topical Agents

Scientifically proven active ingredients for periorbital use:

Hydroquinone (2–4%): The gold standard in depigmenting agents.
Retinoids (tretinoin, retinol): Promote cell regeneration and collagen production.
Vitamin C (L-ascorbic acid): Antioxidant with depigmenting effect.
Niacinamide (Vitamin B3): Prevents melanin transfer and improves skin barrier.
Caffeine: Improves microcirculation and has decongestant properties.

Surgical Blepharoplasty

In certain cases – particularly with significant fat prolapse, markedly excess skin or severe structural change – surgical treatment may be the most effective solution. Lower blepharoplasty addresses dark circles at a structural level. Approaches include transconjunctival blepharoplasty (no visible scarring) and transcutaneous blepharoplasty (with skin incision below the lash line).

Lifestyle and Prevention

Lifestyle factors play a significant role in the development and severity of dark circles. While they cannot completely eliminate genetically or structurally caused dark circles, they can considerably influence the condition and complement professional treatments.

Sleep quality and quantity: 7–9 hours of sleep per night is optimal for most adults. Sleeping on your back with a slightly elevated head reduces lymphatic stasis and morning swelling.
Hydration: Adequate fluid intake (1.5–2.5 litres per day) is essential for skin health.
Diet: A low-sodium diet, antioxidant-rich foods, and adequate iron and vitamin B12 intake support periorbital skin health.
UV protection: Daily sunscreen (SPF 30 or higher) is the most important preventive measure against pigmented dark circles.
Avoid smoking and reduce alcohol: Both accelerate skin ageing and worsen vascular dark circles.
Allergy management: Identifying and avoiding allergens reduces the "allergic shiner" caused by venolymphatic congestion.
