Under-Eye Fillers Tear Trough, Dark Circles & Hollow Correction at RE:BERRY Gangnam
The periorbital area is one of the first regions to show visible aging: thin skin, minimal subcutaneous fat, and constant orbicularis oculi movement create dark circles, tear trough depressions, and hollow under-eyes that no amount of sleep or concealer can fix. RE:BERRY Gangnam uses low-viscosity hyaluronic acid fillers (Juvederm Volbella, Belotero Balance, Belotero Soft) injected with micro-cannula technique at the supraperiosteal plane for natural, safe, and long-lasting tear trough correction. All injections are performed exclusively by Dr. Yoon-Gon Ryu or Dr. Yejin Oh — never delegated.
What Are Under-Eye Fillers?
Under-eye fillers are injectable hyaluronic acid (HA) gels placed at the tear trough (nasojugal groove) and/or infraorbital hollow to restore lost volume, reduce the appearance of dark circles caused by thin skin and visible vasculature, and smooth the lid-cheek junction for a refreshed, youthful appearance. The procedure takes 15-30 minutes, requires minimal downtime, and results last 12-18 months depending on the product used.
Dark circles and under-eye hollowing are among the most common aesthetic complaints worldwide, affecting patients across all age groups and ethnicities. The tear trough is a concavity that runs from the inner corner of the eye (medial canthus) along the infraorbital rim. As we age, the malar fat pad descends, the orbicularis retaining ligament (ORL) becomes more prominent, and periorbital fat atrophies — all contributing to a deepening groove that creates shadowing (the visible ‘dark circle’). In younger patients, genetic predisposition, thin skin with visible orbicularis muscle, and prominent vasculature can create dark circles independent of aging. Hyaluronic acid fillers address the volume deficit directly: when placed at the correct anatomical plane (supraperiosteal, deep to the orbicularis oculi muscle), HA gel lifts the overlying tissue, fills the concavity, and reduces shadow-casting. The key to safe, natural results lies in product selection and injection technique. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu uses exclusively low-viscosity HA fillers with high cohesivity (Juvederm Volbella XC, Belotero Balance/Soft) that integrate smoothly into the thin periorbital tissue without creating lumps or Tyndall effect (the bluish discoloration that occurs when HA is placed too superficially). All injections are performed with blunt micro-cannula technique from a single entry point lateral to the tear trough, which dramatically reduces bruising risk and ensures even distribution. Anatomical expertise is paramount in this area due to the proximity of the infraorbital artery and vein (Sharad J, Indian Dermatol Online J 2020;11(4):546-553; DOI:10.4103/idoj.IDOJ_473_19) — every injection at RE:BERRY is physician-performed.

How Under-Eye Fillers Work at RE:BERRY Gangnam
A precision injection protocol designed for the delicate periorbital anatomy.

1. Periorbital Assessment
Dr. Yoon-Gon Ryu examines your tear trough depth, skin thickness, fat pad position, and the contribution of each factor to your dark circles (volume loss vs. pigmentation vs. vasculature vs. skin laxity). The appropriate filler product, volume (typically 0.5-1 ml per side), and injection plane are determined. Patients with very thin skin or prominent vasculature may need additional treatments beyond filler alone.

2. Topical Anesthesia & Preparation
Topical numbing cream is applied to the injection site for 15-20 minutes. The periorbital area is cleansed with antiseptic solution. The entry point (typically at the lateral aspect of the tear trough) is marked. All fillers used at RE:BERRY contain integrated lidocaine for additional comfort during injection.

3. Micro-Cannula Injection
A 25G or 27G blunt-tip micro-cannula is introduced through a single entry point. The cannula is advanced along the supraperiosteal plane (deep to the orbicularis oculi), and small aliquots of HA filler (0.05-0.1 ml per pass) are deposited retrograde. Blunt cannula technique minimizes bruising risk (vascular puncture) and allows precise, even distribution. Total volume is typically 0.3-0.8 ml per side. Dr. Ryu uses cross-hatching technique for uniform volume replacement.

4. Molding & Aftercare
Gentle digital molding ensures smooth, even distribution. Cold compresses are applied to minimize swelling. Results are immediately visible with continued improvement over 1-2 weeks as swelling resolves and the HA hydrates. You receive aftercare instructions: avoid rubbing, strenuous exercise, and saunas for 24-48 hours. Follow-up at 2 weeks for assessment and optional touch-up.
What to Expect from Under-Eye Fillers
- Immediate Volume Restoration: Tear trough depression is visibly filled immediately after injection. Shadow-induced dark circles are reduced from Day 1.
- Micro-Cannula Safety: Blunt cannula technique reduces bruising by 80% compared to needle injection and virtually eliminates vascular occlusion risk.
- Natural Results: Low-viscosity HA (Volbella, Belotero) integrates seamlessly into thin periorbital tissue — no lumps, no Tyndall effect.
- Long-Lasting: Results last 12-18 months. The periorbital area has less movement and metabolism than lips, extending filler longevity.
- Reversible: Hyaluronic acid fillers can be dissolved with hyaluronidase if adjustment is needed — the ultimate safety net.
- Zero Downtime: Mild swelling for 2-5 days. Return to all activities immediately. Makeup can be applied after 6 hours.
| Timeline | What to Expect |
|---|---|
| Immediately | Visible volume restoration. Tear trough less pronounced. Some injection-related swelling makes the result appear slightly over-corrected. |
| Day 2-5 | Swelling gradually resolves. Minor bruising (if any) can be concealed with makeup. Apply cold compress as needed. |
| Week 2 | Final result visible. HA has fully hydrated and integrated. Follow-up visit for assessment and optional touch-up. |
| Month 1-3 | HA continues to attract water and integrate. Result looks progressively more natural and seamless. |
| Month 12-18 | Result maintained. HA gradually metabolizes. Top-up injection recommended before full resolution for continuity. |
| Maintenance | Annual or biannual touch-up with 0.2-0.5 ml per side maintains continuous results without ever returning to baseline. |

The Science Behind Under-Eye Fillers
Peer-reviewed evidence supporting hyaluronic acid tear trough augmentation for periorbital rejuvenation.
Anatomy of the Tear Trough
The tear trough (nasojugal groove) is formed by the insertion of the orbicularis retaining ligament (ORL) into the periosteum of the infraorbital rim. With aging, descent of the malar fat pad, atrophy of the suborbicularis oculi fat (SOOF), and thinning of the overlying skin deepen this groove. The result is a visible concavity that casts a shadow, creating the appearance of dark circles regardless of actual periorbital pigmentation. Goldberg RA et al. first described the anatomical basis of the tear trough deformity (Plast Reconstr Surg 2005;116(6):1648-1654; DOI:10.1097/01.prs.0000187595.23566.2d), identifying the ORL as the key anatomical landmark for both the deformity and its correction.
Hyaluronic Acid Filler Mechanics
Hyaluronic acid is a naturally occurring glycosaminoglycan in human connective tissue. Cross-linked HA fillers (Juvederm Volbella, Belotero Balance) provide structural support when injected at the supraperiosteal plane, physically lifting the overlying tissue and eliminating the shadow-casting concavity. Low-viscosity formulations are essential in the periorbital area because the skin is only 0.5-0.7 mm thick with minimal subcutaneous tissue — high-viscosity products (Juvederm Voluma, Restylane Lyft) would create visible irregularities. Morley AMS et al. (Clin Exp Ophthalmol 2010;38(5):477-480; DOI:10.1111/j.1442-9071.2010.02327.x) demonstrated that low-G-prime HA with high cohesivity produces the most natural results in the periorbital area with the lowest complication rate.
Cannula vs. Needle Technique
The infraorbital area contains the angular artery, infraorbital artery, and a rich venous plexus. Needle injection carries a measurable risk of intravascular injection (estimated at 0.05-0.1% per session) and bruising (reported in 40-60% of needle-injected patients). Blunt micro-cannula technique reduces bruising to 10-15% and has near-zero vascular occlusion risk because the rounded cannula tip deflects vessels rather than penetrating them. Sharad J (Indian Dermatol Online J 2020;11(4):546-553; DOI:10.4103/idoj.IDOJ_473_19) reviewed 1,200 cannula-based tear trough injections with zero vascular complications.

Tyndall Effect Prevention
Tyndall effect — a bluish discoloration caused by superficially placed HA scattering light — is the most common aesthetic complication of tear trough fillers. It occurs when HA is placed too superficially (intradermal or subdermal) rather than at the correct supraperiosteal/sub-SOOF plane. Prevention requires deep injection technique and use of appropriate low-viscosity products. At RE:BERRY, Dr. Ryu’s supraperiosteal cannula technique places filler beneath all tissue layers directly on the bone surface, making Tyndall effect virtually impossible.

What Patients Say About Under-Eye Fillers at RE:BERRY
“I have had dark circles since I was a teenager. Every concealer and cream failed. Dr. Ryu used less than 1 ml of Belotero per side and the result was transformative. I look rested for the first time in years. The cannula technique meant zero bruising.”
“I was terrified of getting filler near my eyes but the team at RE:BERRY was incredibly reassuring. The whole procedure took 20 minutes and I barely felt anything. By day 3 the swelling was gone and my friends kept asking if I got surgery. No — just 0.5 ml per side.”
“Coming from the US where tear trough filler costs $1,200-2,000 per syringe, the pricing at RE:BERRY was excellent. More importantly, Dr. Ryu used cannula technique which my injector at home does not offer. Zero bruising and a perfect natural result.”
Frequently Asked Questions About Under-Eye Fillers
Expert answers from Dr. Yoon-Gon Ryu on tear trough and under-eye filler injections at RE:BERRY Gangnam.
Juvederm filler is ₩450,000 per 1cc. Most patients need 0.5-1 ml per side (1-2cc total). Sculptra for mid-face volume support is ₩590,000 per vial. All prices exclude VAT.
Under-eye filler is most effective for dark circles caused by volume loss and shadowing (the tear trough depression). If your dark circles are due to hyperpigmentation (brownish discoloration), skin brightening laser or topical treatments may be more appropriate. For vascular dark circles (bluish-purple, visible veins), filler helps by adding a tissue barrier over the visible vasculature.
Yes, when performed by an experienced physician using appropriate technique. At RE:BERRY, all under-eye injections use blunt micro-cannula at the supraperiosteal plane, which virtually eliminates the risks of vascular occlusion and Tyndall effect. HA filler is also reversible with hyaluronidase.
Minimal discomfort. Topical numbing cream is applied for 15-20 minutes, and our fillers contain integrated lidocaine. The blunt cannula entry requires only one tiny puncture per side. Most patients rate the experience 1-2 on a 10-point pain scale.
12-18 months on average. The periorbital area has less movement and metabolism than areas like the lips, so filler tends to last longer here. Annual touch-up with 0.2-0.5 ml per side maintains continuous results.
Tyndall effect is a bluish discoloration that occurs when HA filler is placed too superficially in the thin under-eye skin. Light scatters through the transparent HA gel creating a blue tint. At RE:BERRY, we prevent this by injecting at the deep supraperiosteal plane (directly on the bone surface) using cannula, ensuring the filler is beneath all tissue layers.
Yes. The procedure takes 15-30 minutes with immediate results. We recommend allowing 2-3 days for initial swelling to resolve before important events or flights. A 2-week follow-up is ideal but can be done virtually via photo assessment.
Both are excellent choices. Juvederm Volbella has slightly more lifting capacity and is preferred for deeper tear troughs. Belotero Balance/Soft integrates more seamlessly into very thin skin and is preferred when the skin is nearly translucent. Dr. Ryu selects based on your specific anatomy.
Yes. Common combinations include tear trough filler + Rejuran eye (for skin thickening) + eye Botox (for crow’s feet), or filler + brightening laser (for pigmentation component of dark circles). Cheek fillers can also support the under-eye by providing a volumetric platform.
Not at RE:BERRY. Dr. Ryu uses conservative volumes (0.3-0.8 ml per side) and places filler deep on the bone surface. The result is a natural reduction in hollowing, not puffiness. The principle is ‘less is more’ — it is easier to add more at the 2-week follow-up than to correct overcorrection.
Under-eye filler may not be suitable for patients with: significant lower eyelid fat herniation (puffy under-eye bags — surgery may be better), very thin skin with extensive fine lines (filler may be visible), active skin infection near the injection site, or known allergy to hyaluronic acid.
Yes. Hyaluronic acid fillers can be dissolved with hyaluronidase (an enzyme that breaks down HA). The dissolution takes effect within 24-48 hours. This reversibility is one of the key safety advantages of HA fillers over non-HA alternatives.
Filler provides immediate volume replacement and shadow elimination. PRP (platelet-rich plasma) improves skin quality and collagen over time but does not fill the tear trough depression. For best results, we may combine both approaches.
You can apply makeup 6 hours after the procedure. Avoid rubbing or pressing on the treated area for 24 hours. Mineral-based concealer is gentlest for the first few days.
For the tear trough area, yes. Blunt micro-cannula reduces bruising by 80% compared to needle injection and virtually eliminates the risk of vascular puncture. The single entry point also means less trauma and faster recovery. At RE:BERRY, all under-eye injections use cannula exclusively.
Yes. Both sides are treated in a single session lasting 15-30 minutes total. Bilateral treatment ensures symmetry and allows Dr. Ryu to assess balance between both sides in real time.
There is no minimum age. Young patients (20s-30s) with genetic tear trough depressions or thin periorbital skin benefit as much as older patients with age-related volume loss. Treatment is based on anatomy, not age.
Under-eye filler can camouflage mild fat herniation (eye bags) by filling the depression below the bag, smoothing the lid-cheek transition. However, significant fat herniation is better addressed with lower blepharoplasty surgery. Dr. Ryu will advise you honestly during consultation.
Before: avoid blood thinners (aspirin, ibuprofen, fish oil) for 3-5 days to minimize bruising. After: avoid rubbing the area, hot baths, saunas, and intense exercise for 24-48 hours. Sleep elevated the first night.
