The under-eye area (tear trough) is widely considered one of the most technically demanding and unforgiving areas in aesthetic medicine. Unlike the lips or cheeks, the periorbital skin is extremely thin, highly mobile, and sits directly over delicate vascular and lymphatic structures. A filler that performs beautifully in the cheeks can look disastrous under the eyes — causing visible lumps, bluish discoloration (Tyndall effect), or chronic puffiness.
The ideal under-eye filler must possess a unique combination of properties: extremely low G-prime (softness), minimal water absorption (to prevent swelling), seamless tissue integration, and a near-zero risk of the Tyndall effect. Only a handful of products on the market are truly optimized for this delicate area, and even among those, proper patient selection and injection technique remain paramount.
This guide compares eight of the most widely used and clinically validated under-eye filler brands: Teosyal Redensity 2, Belotero Balance, Restylane Eyelight, Sunekos 120, Juvéderm Volbella, Neuramis Light, Rejuran Healer, and Profhilo. It focuses on formulation, safety profiles, integration characteristics, longevity, regulatory considerations, and real-world feedback from both practitioners and patients.
⚠️ IMPORTANT MEDICAL DISCLAIMER
Under-eye fillers are medical devices that must be handled, prescribed, and administered only by appropriately qualified healthcare professionals with advanced anatomical knowledge of the periorbital region. The tear trough area carries elevated risks including vascular occlusion (which can cause blindness), Tyndall effect, and chronic edema.

2. What Makes a Good Under-Eye Filler? (vs. Other Fillers)
The periorbital region has unique anatomical characteristics that demand specific filler properties. A filler that performs beautifully in the lips or cheeks can produce visible lumps, bluish discoloration, or chronic puffiness when used under the eyes.
Key Requirements for Under-Eye Fillers:
- Extremely Low G-Prime: The under-eye skin is the thinnest on the body (0.5mm). Fillers must be exceptionally soft to avoid visible lumps or palpability.
- Minimal Water Absorption (Low Hydrophilicity): The periorbital area is prone to lymphatic congestion. Fillers that attract water can cause chronic puffiness or “bags” under the eyes.
- Seamless Tissue Integration: The filler must blend invisibly with native tissue to avoid visible edges or the Tyndall effect (bluish discoloration when light hits the filler).
- Low Risk of Tyndall Effect: Some HA fillers scatter light when placed superficially, creating an unnatural blue hue. Under-eye fillers must minimize this risk.
- Appropriate Injection Depth: Most under-eye fillers must be placed deep (pre-periosteal or sub-orbicularis) to avoid visibility. Superficial placement dramatically increases complication risk.
Why Most Fillers Don’t Work Well Under the Eyes:
Fillers designed for other areas (like Juvéderm Voluma for cheeks or Restylane Kysse for lips) have properties that make them unsuitable for the tear trough:
- High G-prime fillers feel firm and look unnatural in thin periorbital skin
- Highly hydrophilic fillers attract water, causing chronic puffiness
- Fillers with larger particle sizes increase Tyndall effect risk
- Fillers designed for dynamic areas (lips) may migrate in the relatively static under-eye region
3. How to Compare Under-Eye Filler Brands
A meaningful comparison requires understanding the unique requirements of the periorbital region. Clinicians evaluate under-eye fillers based on:
- 🧬 G-Prime (Firmness): Lower G-prime = softer feel. Ideal for under-eye is extremely low G-prime.
- 💧 Hydrophilicity (Water Absorption): Lower hydrophilicity = less risk of chronic puffiness. Critical for under-eye area.
- 🔬 Particle Size: Smaller, more uniform particles reduce Tyndall effect risk.
- 🎯 Tissue Integration: How seamlessly the filler blends with native tissue.
- ⏱️ Longevity: How long the filler maintains results in the under-eye area (typically 9-18 months).
- 🛡️ Safety Profile: Risk of Tyndall effect, edema, lumps, and vascular complications.
- 🌍 Regulatory Status: Whether the product is specifically approved for periorbital use or used off-label.

6. Safety Considerations and Risk Management
⚠️ CRITICAL SAFETY WARNING: PERIORBITAL VASCULAR OCCLUSION
The under-eye area carries elevated risk of vascular occlusion due to the dense vascular network surrounding the orbit. Accidental injection into a blood vessel can cause tissue necrosis or, in rare cases, blindness. Practitioners must have extensive knowledge of periorbital anatomy, use appropriate injection techniques (deep placement, aspiration before injection), and have an emergency protocol in place, including immediate access to hyaluronidase (for HA fillers).
Key Safety Considerations for Under-Eye Fillers:
- Tyndall Effect: Bluish discoloration when filler is placed too superficially or in patients with very thin skin. Risk varies by product — Belotero and Teosyal Redensity 2 have the lowest risk.
- Chronic Edema (Puffiness): Fillers with high hydrophilicity can attract water, causing persistent under-eye bags. Low-hydrophilicity fillers (Teosyal Redensity 2, Belotero) minimize this risk.
- Visible Lumps/Irregularities: Can occur if filler is placed too superficially or in excessive volumes. Low G-prime fillers reduce this risk.
- Vascular Occlusion: Rare but serious complication. Requires immediate treatment with hyaluronidase (for HA fillers) and emergency protocols.
- Patient Selection: Not all patients are suitable candidates. Patients with significant fat pad herniation, severe skin laxity, or active skin conditions may not benefit from under-eye fillers.
Contraindications:
- Active infection or skin disease in the treatment area
- Known allergy to any component of the product
- History of severe allergic reactions or anaphylaxis
- Bleeding disorders or use of anticoagulants
- Unrealistic expectations or body dysmorphic disorder
- Significant fat pad herniation (may require surgical intervention)
- Severe skin laxity (fillers may not provide satisfactory results)
7. Regulatory Status and Supply Chain Verification
The under-eye filler market is unfortunately plagued by counterfeit products and unregulated imports. For clinics and distributors, verifying the supply chain is a matter of patient safety and legal compliance.
Before purchasing, verify the following:
- Regulatory Approval: Ensure the product has a valid CE Mark (Europe), FDA clearance (USA), or equivalent local health authority approval. Note that many under-eye fillers are used off-label — verify that the practitioner is experienced with off-label use.
- Authorized Distributors: Purchase only directly from the manufacturer or their explicitly authorized national distributors.
- Authentication Features: Check for holographic seals, unique QR codes, or scratch-off verification labels on the packaging.
- Temperature Control: Most HA fillers require refrigerated storage (2–8°C). Verify that the supplier maintains proper cold-chain logistics.
Never purchase under-eye fillers from unauthorized online marketplaces, social media sellers, or unverified third-party wholesalers. Counterfeit Teosyal Redensity 2, Belotero, and Korean fillers are among the most common fake products on the black market.
8. Frequently Asked Questions (FAQ)
❓ Which under-eye filler is the best?
There is no universally “best” under-eye filler — the optimal choice depends on the patient’s specific anatomy, skin thickness, tear trough severity, and the practitioner’s expertise. Teosyal Redensity 2 is widely regarded as the gold standard for tear trough correction due to its periorbital-specific formulation. Belotero Balance is the most commonly used HA filler for under-eye use in the US due to its low Tyndall risk. For patients seeking skin quality improvement rather than volume restoration, Rejuran Healer and Profhilo offer unique benefits.
❓ What is the difference between under-eye fillers and skin boosters?
Under-eye fillers (like Teosyal Redensity 2, Belotero) provide subtle volume restoration to correct tear trough deformities. Skin boosters (like Profhilo, Rejuran Healer) improve skin quality, hydration, and texture without adding significant volume. Fillers are ideal for patients with visible tear troughs, while skin boosters are ideal for patients with fine lines, crepiness, or dark circles due to poor skin quality.
❓ Are Korean under-eye fillers (Neuramis, Rejuran) as good as European brands?
Clinical data and practitioner feedback suggest that authentic, properly regulated Korean under-eye products offer comparable safety and efficacy to premium Western brands for most indications. Neuramis Light provides excellent tissue integration at a lower cost, while Rejuran Healer offers unique polynucleotide-based benefits for skin quality improvement. The key is ensuring product authenticity through authorized supply chains.
❓ How long do under-eye filler results last?
Duration varies by product and individual factors. HA fillers typically last 6-12 months in the under-eye area. Skin boosters like Profhilo and Rejuran typically last 6-9 months. Individual results vary significantly based on metabolism, lifestyle, and the specific product used.
❓ Can under-eye fillers be dissolved?
Only HA-based fillers can be dissolved using hyaluronidase. Polynucleotide-based products (Rejuran Healer) cannot be dissolved and must naturally metabolize over time. This makes proper product selection and injection technique critical for under-eye treatments.
❓ What is the Tyndall effect and how can it be avoided?
The Tyndall effect is a bluish discoloration that occurs when HA filler is placed too superficially in thin skin, causing light to scatter. It can be avoided by using fillers with low Tyndall risk (Belotero, Teosyal Redensity 2), injecting at the correct depth (deep, pre-periosteal), and using conservative volumes. If Tyndall effect occurs, it can be treated with hyaluronidase.
❓ Are under-eye fillers painful?
Most patients report mild to moderate discomfort during under-eye filler injections. Most products contain lidocaine for enhanced comfort. Practitioners may also use topical anesthetics or ice to minimize discomfort. The under-eye area is sensitive, but most patients tolerate the procedure well.
❓ What is the downtime after under-eye filler treatment?
Most under-eye fillers have minimal downtime. Patients may experience mild swelling, redness, or bruising at injection sites, which typically resolves within 24-72 hours. Products like Teosyal Redensity 2 and Belotero are particularly known for their minimal downtime, allowing patients to resume normal activities immediately after treatment.
9. Conclusion: Choosing an Under-Eye Filler Based on Evidence
Teosyal Redensity 2, Belotero Balance, Restylane Eyelight, Sunekos 120, Juvéderm Volbella, Neuramis Light, Rejuran Healer, and Profhilo each offer distinct advantages for periorbital rejuvenation. The choice should be driven by the patient’s specific concerns (tear trough volume vs. skin quality), anatomy, skin thickness, and the practitioner’s expertise — not by marketing trends or brand prestige alone.
A reliable approach prioritizes:
- Matching the product’s properties (G-prime, hydrophilicity, particle size) to the patient’s specific periorbital anatomy and concerns.
- Understanding whether the patient needs volume restoration (HA fillers) or skin quality improvement (skin boosters/polynucleotides).
- Sourcing exclusively from authorized, traceable supply chains — especially for Korean-manufactured products.
- Ensuring the procedure is performed by a qualified, anatomically trained medical professional with extensive experience in periorbital injections.
- Proper patient selection — not all patients are suitable candidates for under-eye fillers.
For healthcare professionals and qualified buyers, the strongest decisions are supported by verifiable clinical data, rigorous safety protocols, and legitimate supply chains.
