"Dark circles under the eyes" is a single complaint with at least four different anatomical causes — and treating the wrong cause produces no improvement. Korean dermatology has developed a diagnostic framework that classifies dark circles into four categories, each requiring different treatment. This guide explains the framework and how Korean clinics match treatment to category.
Why "dark circles" need diagnosis first
Patients arrive saying "I have dark circles" — but the underlying cause varies dramatically:
- Pigmentation type — actual melanin deposit in skin.
- Hollowness type — tear-trough volume loss creating shadow.
- Vascular type — visible blood vessels through thin skin.
- Shadowing type — eyebag protrusion casting shadow below.
Most patients have a combination of two or more types. Treatment that addresses only one will leave the others visible.
Category 1: Pigmentation
Diagnosis
- Brown or grey-brown discoloration.
- Persists when skin is stretched.
- Often hereditary; common in Asian and Mediterranean skin types.
- May worsen with sun exposure or rubbing.
Korean treatment options
- Picosecond laser (PicoSure, PicoWay) — fragments melanin without heat damage to delicate periorbital skin.
- Q-switched Nd:YAG laser — series of treatments for melanin breakdown.
- Topical regimens — tranexamic acid, vitamin C, retinol, kojic acid.
- Chemical peels — gentle formulations safe for periorbital skin.
- Pricing — ₩150,000–₩400,000 per laser session; series of 4–6.
Category 2: Hollowness
Diagnosis
- Tear-trough depression below lower eyelid.
- Worse with fatigue or weight loss.
- Smartphone-camera flash test reveals shadow.
- Disappears when stretched upward.
Korean treatment options
- HA filler tear-trough injection — most common; immediate result.
- Special HA formulations designed for thin periorbital skin (low water-binding).
- Conservative volumes (0.3–0.5ml total) — overcorrection causes Tyndall effect.
- Cannula technique standard in experienced Korean clinics.
- Lasts 9–18 months.
- Fat grafting — for severe hollowness or those wanting permanence.
- Pricing — ₩400,000–₩800,000 for filler; ₩1,500,000+ for fat grafting.
Category 3: Vascular
Diagnosis
- Bluish or purple tinge.
- Visible underlying vessels through thin skin.
- Worse when tired (vasodilation).
- Common in fair skin or thin-skinned individuals.
Korean treatment options
- Vascular laser (Vbeam, Excel V) — targets visible vessels.
- Skin thickening treatments — Rejuran I (specifically formulated for periorbital), Profhilo, exosomes.
- Long-term skin quality investment — collagen-stimulating treatments thicken skin over time.
- Vascular type is often the hardest to improve dramatically.
- Pricing — ₩300,000–₩500,000 per Rejuran I session; series of 3–4.
Category 4: Shadowing from eyebags
Diagnosis
- Protrusion of orbital fat below lower lid.
- Casts shadow downward.
- Skin underneath may be normal color.
- Worse with tilted lighting.
Korean treatment options
- Lower blepharoplasty (transconjunctival) — fat repositioning or removal; no external scar.
- Fat repositioning — moves protruding fat down into tear-trough hollow (addresses two issues simultaneously).
- Pinch blepharoplasty — for skin excess only.
- Pricing — ₩2,500,000–₩5,000,000.
The combination reality
Most Korean patients with dark-circle complaint have:
- Pigmentation + hollowness combination (most common).
- Hollowness + shadowing combination.
- Vascular + pigmentation in fair-skinned individuals.
Korean clinics typically address the dominant cause first, reassess, then layer additional treatment. Single-modality "dark circle treatment" claims should be viewed skeptically.
Diagnostic tools used in Korean consultations
- Stretch test — pulling skin laterally; pigmentation persists, vascular fades.
- Wood\'s lamp — UV light reveals melanin distribution depth.
- Smartphone flash test — direct light eliminates shadow; remaining darkness is pigmentation/vascular.
- Skin pinch — assesses skin thickness for vascular contribution.
- Photographic documentation — natural lighting baseline.
What doesn\'t work for dark circles
- Generic "dark circle creams" without active ingredients matched to type.
- Treating pigmentation type with filler (no improvement).
- Treating hollowness type with bleaching agents (no improvement).
- Aggressive skincare causing irritation and worsening pigmentation.
- Concealer alone as long-term strategy (does not address cause).
What Korean clinics get right
- Diagnostic categorization before treatment selection.
- Periorbital-specific products (Rejuran I designed for thin skin).
- Conservative filler volumes and cannula technique.
- Combination protocols when multiple causes coexist.
- Skin-quality investment for vascular cases (long-term thinking).
The honest framing
"Dark circles" is a single visible complaint with multiple anatomical causes that respond to entirely different treatments. The patients who get good results in Korean clinics are those whose clinicians diagnose category first and treat accordingly. The patients who pursue generic "dark circle treatment" without diagnostic categorization spend money on inappropriate procedures and come away disappointed. Match treatment to category, layer when categories combine, and invest in long-term skin quality where appropriate — that is the framework Korean dermatology has refined.
