Periorbital Pigmentation
Dark circles (periorbital hyperpigmentation, POH) are among the most common cosmetic complaints of the face. The skin around the eye socket — upper lids, lower lids and the tear trough — looks noticeably darker and duller than the surrounding skin. Periorbital skin averages only about 0.5 mm thick, the thinnest on the body, with very few oil glands and a dense network of tiny vessels just beneath the epidermis. This anatomy makes it highly sensitive to pigment changes, venous pooling and the loss of fat volume that comes with age. Dark circles not only make the face look tired and older than it is; they can also reflect problems with microcirculation, genetics, chronic allergy or lifestyle.
The causes are complex and multifactorial, ranging from melanin buildup in the epidermis and dermis, dilated lower-lid veins and thin skin that lets vessels show through, to shadowing from a tear trough deformity and herniated eyelid fat. If the main cause is misread and the wrong treatment is chosen — for example, a pigment laser for dark circles that are really due to lost fat volume — the result is no improvement and possibly irritation and post-inflammatory hyperpigmentation (PIH).
At Haute-Derma, we take a strictly individualized medical approach to dark circles. Using multispectral skin analysis, detailed dermoscopy and a clinical exam that sorts dark circles into the four internationally recognized types, we build a layered treatment plan. It combines 1064 nm picosecond laser, hyaluronic acid microinjections to rejuvenate the tear trough, gentle chemical peels designed for the eye area and actives that boost microcirculation — restoring a fresher, brighter, more rested look to the eyes.
Causes and Mechanisms of Dark Circles
Dark circles result from a combination of four main biological and anatomical mechanisms:
- Multilayer Melanin Buildup (Pigmentary Component): Excess melanin in the epidermis or papillary dermis around the eyes. Causes include genetics (common in Fitzpatrick skin types IV–VI), cumulative UV exposure, and post-inflammatory hyperpigmentation in people with a history of atopic dermatitis, allergic contact dermatitis, or chronic eye rubbing from allergic conjunctivitis.
- Microcirculation Problems and Dilated Veins (Vascular Component): The superficial capillaries and veins of the lower lid become congested and dilated, or hemosiderin (a breakdown product of red cells that have leaked from vessels) collects there. Because lower-lid skin is so thin, this congested venous network shows through as a blue-purple or deep red color. It gets worse with lack of sleep, stress, heavy crying or during the menstrual cycle.
- Skin Thinning and Structural Atrophy (Structural Component): Natural aging depletes collagen and elastin and thins the epidermis around the eyes. As the skin and underlying tissue become very thin, the dark orbicularis oculi muscle and the superficial vessels beneath show clearly through, making the circles look darker.
- Shadowing From Anatomical Hollows (Shadowing Component): Loss of periorbital fat, reduced orbital bone density and bulging lower-lid fat pads create a deep tear trough. Under overhead light, this hollow casts a dark shadow beneath the eye that mimics dark circles even though the skin pigment is entirely normal.
Classifying the Four Clinical Types of Dark Circles
| Type | Clinical Color | Dermoscopy and Structural Features |
|---|---|---|
| Pigmentary (P) | Light brown, dark brown or gray-brown; evenly spread over upper and lower lids | Color does NOT change when the lower-lid skin is stretched. Brown epidermal pigment network or speckled gray-blue dermal melanin |
| Vascular (V) | Dusky purple, blue-purple or deep red; mainly on the lower lid, sometimes with mild puffiness | Color DEEPENS or vessels become more visible when the skin is stretched. Scattered dilated capillaries, pale blue superficial venous plexus or hemosiderin streaks |
| Structural (S) | Shadow-like darkness over a deep tear trough or lower-lid fat bags | Darkness DISAPPEARS COMPLETELY with direct frontal light or gentle upward skin traction. Thin skin with loss of fat volume; no excess melanin or abnormal vessels |
| Mixed (M) | Most common (> 60%): brown-gray with a purple tinge, plus a tear trough | Color changes partly when the skin is stretched. A mix of melanin spots, dilated vessels and tear trough hollowing |
Examination, Dermoscopy and Classification at Haute-Derma
- Clinical Exam and Skin Stretching Test: The doctor gently stretches the lower-lid skin sideways with two fingers. If the color stays the same → pigmentary (P); if it gets darker → vascular (V); if it disappears → structural/shadowing (S).
- Multispectral UV Skin Analysis and Periocular Dermoscopy
- UV/Wood's light: Shows how deep the melanin lies (epidermal or dermal).
- Dermoscopy: Assesses epidermal thickness and reveals hidden dilated vessels and hemosiderin deposits.
- Orbital Structure and Tear Trough Depth: The tear trough is graded on the Barton scale (Class I–III) to plan volume restoration.
Our Layered Treatment Protocol at Haute-Derma
At Haute-Derma, the treatment plan for dark circles is tailored to the clinical type:
Treating the Pigmentary Type
- 1064 nm Picosecond Laser (Periocular Pico Toning): Ultrashort picosecond pulses at 1064 nm and very gentle fluences (0.4–0.8 J/cm²) break up epidermal and dermal melanin without injuring or swelling the delicate eyelid skin.
- Periocular Chemical Peel: A specialized peel combining lactic acid, arbutin, citric acid and low-strength TCA (3.75%–10%) gently removes pigment-laden surface cells and brightens the skin around the eyes.
Treating the Vascular Type
- Long-Pulse 1064 nm Nd:YAG Laser / Vascular IPL: Light energy absorbed by oxyhemoglobin coagulates and shrinks the tiny dilated veins under the lower lid, reducing the dusky purple tone.
- Mesotherapy and Iontophoresis to Boost Microcirculation: Microinjection or iontophoresis of vitamin K oxide, caffeine, tranexamic acid and rutin strengthens vessel walls, reduces puffiness and clears hemosiderin deposits.
Treating the Structural and Shadowing Type
- Hyaluronic Acid Tear Trough Filler: A soft cross-linked HA designed for the eye area (such as Teosyal Redensity II or Restylane Refyne) is placed with a blunt cannula (27G/30G) just above the orbital bone. This fills the hollow tear trough and removes the shadow immediately.
- Polynucleotide Biostimulation (PN / PDRN / Rejuran I): Microinjections of salmon-DNA–derived polynucleotides stimulate collagen, thicken the lower-lid dermis, cover superficial vessels and improve skin elasticity.
