The tear trough is the groove extending from the inner corner of the eye along the infraorbital rim, formed by the anatomy between the orbicularis oculi muscle and skin (orbital ligament attachment) — when pronounced, it casts a shadow over the under-eye area, making the face look tired, aged, and listless: the so-called ‘structural dark circles.’ Causes include: (1) Congenital structure — a taut orbital ligament attachment at the infraorbital rim, with a naturally prominent tear trough common even in young people. (2) Aging — collagen loss and fat pad atrophy and descent deepening the under-eye depression over time. (3) Fat pad position — the shape and position of the lower eyelid fat pads influence trough depth. (4) Lifestyle — sleep deprivation, eye strain, and rapid weight loss accentuate the trough. Previously the tear trough was often mistaken for simple dark circles that concealer cannot truly fix — HA tear trough filler directly restores volume to the hollow, smoothing the groove and eliminating the shadow, non-surgically in 30 minutes. Rappoel Dermatology near Gangnam Station, Seoul, provides HA tear trough filler treatment.
Technical Principles of HA Tear Trough Filler
- Volume restoration, not concealment: A tear trough is fundamentally a hollow — HA is injected into the soft-tissue layer of the infraorbital depression, restoring volume so the groove is level with surrounding skin and light reflection becomes uniform, naturally erasing the shadow
- Low-G’ small-molecule HA: Under-eye skin is extremely thin with frequent expression movement — low-G’ (soft) small- or medium-molecule HA is used; the soft texture prevents lumps or a ‘caterpillar’ appearance and feels natural
- Precise injection depth: The key to tear trough injection is the layer — injection into the deep supraperiosteal plane above the orbicularis, avoiding too-superficial injection (blue Tyndall lumps) and excessive depth or volume pressing on vessels; typically only 0.3-0.7ml per side
- Anatomically safe injection: The periorbital area is rich in vessels (supraorbital, angular arteries); injectors must know vessel courses — blunt cannulas and aspiration technique markedly reduce intravascular risk (skin necrosis, and the very rare but serious risk of blindness)
- Reversibility: Unsatisfactory results can be dissolved with hyaluronidase — reversibility matters especially in this high-risk zone
Treatment Strategies for Different Under-Eye Concerns
- Pure tear trough hollow (no fat bulge): Hollow groove with a flat lower eyelid. Strategy: 0.3-0.5ml per side at the supraperiosteal plane — directly leveling the groove with natural results
- Tear trough with eye bags: Hollow plus protruding lower eyelid fat (eye bags). Strategy: assess bag severity first — mild bags may be visually balanced by trough filling alone; moderate-to-severe bags suggest blepharoplasty or combination treatment; Rappoel honestly recommends the most appropriate approach
- Tear trough with dark circles (pigmentary): Hollow plus pigmentation. Strategy: HA to level the depression plus laser/whitening IV for pigment — fix the shadow first, then the pigment, with synergistic results
- Aging trough (with fine lines): Collagen loss with visible periorbital fine lines. Strategy: trough filler plus periorbital toxin (lines) or Thermage eye treatment (tightening) — volume plus firmness
- Congenital prominent trough (young group): Naturally deep trough at age 20-30. Strategy: minimal injection (0.3ml per side) gives obvious improvement — young elastic skin needs only a little volume to smooth the groove
Rappoel Tear Trough Filler Protocol
- Consultation assessment (5 min): Frontal and oblique evaluation of trough depth, eye bags, dark circle type, skin thickness → distinguish trough from dark circles/bags → design the injection plan (points, depth, volume) → importantly, assess vascular anatomy risk and suitability
- Cleansing and anesthesia (10 min): Periorbital makeup removal → alcohol disinfection → topical anesthetic cream for 15 minutes (or local cooling) → reconfirm the disinfected area before injection
- Precise injection (10-15 min): Micro-injection with a blunt cannula or fine needle at the supraperiosteal plane → 0.3-0.7ml per side across 2-3 points → mold and press while injecting, observing the hollow leveling → avoid overfilling
- Result confirmation (3 min): Patient sits up to check the mirror → verify frontal (trough smoothed) and oblique views (shadow eliminated) → ice pack for 3-5 minutes to reduce swelling
- Post-care instructions (2 min): Avoid pressing the under-eye area and sleeping face-down for 24 hours → avoid high-temperature environments and spicy food for 48 hours → avoid under-eye massage, beauty devices, and strenuous exercise for 1 week → 2-4 week follow-up for effect and absorption
Tear trough filler takes about 30 minutes (including anesthesia), with the hollow visibly smoothed immediately and results lasting 12-18 months (periorbital HA metabolizes slowly — among the longest-lasting injection sites). Located 3 minutes from Gangnam Station Exit 10, with seamless English and Chinese consultation.
Frequently Asked Questions
What’s the difference between tear trough filler and eye bag surgery?
They address different problems: (1) Tear trough filler — treats the ‘hollow’: HA restores volume to the depression, suitable for pure troughs without prominent bags. Non-surgical, 30 minutes, no downtime, lasts 12-18 months, reversible (dissolvable). (2) Eye bag surgery — treats the ‘bulge’: removes or repositions lower eyelid fat, suitable for prominent fat bags (moderate-to-severe). Surgical, 1-2 weeks recovery, long-lasting. (3) Clinical key — many patients have both trough and bags: filling the trough can make bags more prominent, while removing fat can worsen the trough — the correct approach evaluates their relative severity. Rappoel physicians analyze during consultation and recommend single or combined treatment, avoiding the ‘fix A, worsen B’ dilemma.
Is tear trough filler safe? Is there a blindness risk?
Safety and risk: (1) The periorbital area is rich in vessels, and injection carries a very rare intravascular risk (skin necrosis, blindness) — but such risks are mainly technique-related. (2) Risk reduction — experienced physicians familiar with periorbital anatomy; blunt cannulas or aspiration; small divided injections; vessel assessment beforehand. (3) Common side effects — swelling and bruising (most common, 3-7 days), temporary unevenness (improves with gentle massage), and blue Tyndall appearance from too-superficial injection (dissolvable and repairable). (4) Rappoel’s principle — safety is the top priority for periorbital treatment; results are kept understated rather than taking unnecessary risks; vascular risk is carefully assessed before treatment.
How long does tear trough filler last? Will it look unnatural?
Duration and naturalness: (1) Duration — periorbital HA metabolizes slowly; tear trough results typically last 12-18 months, among the longest of any injection site. (2) Naturalness — the key is volume and depth: only 0.3-0.7ml per side, a micro-volume adjustment; correct depth (supraperiosteal) and soft texture (low G’) leave no visible traces — people only notice ‘you look more refreshed.’ (3) Standard — a good tear trough filler ‘makes the hollow disappear without looking injected,’ not a bulging ‘caterpillar’ or blue lump. (4) Rappoel’s principle — small volume, stepwise approach: start conservative, follow up at 2-4 weeks, then decide whether to top up.
Are tear troughs and dark circles the same? Will dark circles disappear after filler?
They are different concepts: (1) Tear trough — a structural hollow where light creates a shadow resembling dark circles (shadow-type dark circles). (2) Three dark circle types — vascular (thin skin revealing bluish vessels), pigmentary (melanin deposits appearing brown-black), structural (shadow from trough/bags). (3) Filler’s effect — remarkable for structural (shadow) type: leveling the hollow erases the shadow, visually lightening ‘dark circles’ immediately. (4) But for pure vascular or pigmentary types — HA has no direct effect; laser (pigmentary), lifestyle improvement (vascular), or whitening IV are needed. (5) Rappoel physicians distinguish the type during consultation and recommend the most effective combination for the root cause.
Who is not suitable for tear trough filler?
The following should be cautious or avoid: (1) Prominent lower eyelid fat (moderate-to-severe bags) — filler alone may make bags more visible; address the bags first. (2) Active periorbital infection (stye, folliculitis, blepharitis) — wait for full healing. (3) Pregnancy and breastfeeding — postpone. (4) Autoimmune disease, bleeding disorders, or long-term anticoagulant use — physician evaluation required (higher bruising risk). (5) HA allergy. (6) Unrealistic expectations — filler significantly improves hollowness and the tired look but cannot reverse all aging; Rappoel honestly explains the limits of treatment without overpromising.
