Common Target Areas

Tear Trough (Infraorbital Hollow) Under Eye Area Palpebromalar Groove Upper Mid-Face Transition Periorbital Fine Lines

Tear Trough Filler London: Clinical Under-Eye Restoration

For patients seeking a medically-led tear trough filler london treatment, the infraorbital region demands the highest level of anatomical expertise. The under-eye area is one of the most technically challenging zones in facial aesthetics — the skin is less than 0.5mm thick, underlain by a dense vascular network and delicate orbital structures that leave no margin for error.

As we age, structural volume loss in the mid-face causes the infraorbital fat pads to descend, creating deep grooves known as hollow tear troughs. This casts a shadow beneath the eyes, producing the appearance of permanent dark circles and fatigue — even in well-rested patients. A deep tear trough or sunken palpebromalar groove can age the face by a decade, making patients appear exhausted regardless of sleep quality.

At PRP London Clinic, 33 Cavendish Square (in the heart of London’s Harley Street medical district), our GMC-registered doctors use Teosyal Redensity II — a low-hydrophilic Hyaluronic Acid gel specifically formulated for the periorbital region — to precisely restore lost volume via micro-cannula. This under eye filler london treatment lifts hollows, softens shadows, and smooths the transition between the lower eyelid and upper cheek for a naturally refreshed, rested appearance.

This procedure is part of our comprehensive Guide to Under-Eye Hollowing & Tear Trough Deformity.

Your Tear Trough Filler Doctors in London

Every tear trough filler london session is performed by a GMC-registered doctor from our clinical team — Dr Bruno Amendola (GMC: 4346629), Dr Mohamed Nafei (GMC: 7520509), and Dr Reem Nouri (GMC: 6149512). Our doctors follow standardised treatment protocols developed through shared clinical workflows, ensuring consistent outcomes regardless of which physician performs your procedure. Never a nurse, technician, or non-medical practitioner.

What Can Tear Trough Fillers Treat?

Infraorbital Hollowing & Volume Loss

The primary indication for fillers for tear troughs is structural hollowing caused by age-related volume loss in the infraorbital region. As the deep medial cheek fat pad (SOOF — sub-orbicularis oculi fat) atrophies with age, the bony orbital rim becomes increasingly visible, creating the characteristic hollow tear trough groove. HA filler placed pre-periosteally along the orbital rim restores this lost volume, lifting the shadow that creates the illusion of permanent dark circles.

Under-Eye Dark Circles (Shadow-Based)

Many patients seeking under eye filler present with dark circles caused not by pigmentation but by structural shadowing. When the tear trough groove deepens, overhead and ambient lighting casts a shadow into the concavity, producing a dark discolouration that no concealer can mask. By restoring the smooth convex contour between the lower eyelid and cheek, dermal filler tear trough treatment eliminates the shadow at its source.

Under-Eye Wrinkles & Fine Lines

Patients searching for under eye filler for wrinkles may benefit from Teosyal Redensity II’s unique Dermo-Restructuring Complex — a blend of 14 essential nutrients including amino acids, antioxidants, and minerals that supports dermal quality alongside volumisation. While filler alone cannot erase established wrinkles, the combination of volume restoration and dermal nourishment can visibly soften fine crepey lines in the periorbital region.

Male Tear Trough Treatment

We frequently perform male tear trough filler treatments to refresh tired-looking eyes while preserving masculine mid-face architecture. Men typically present with deeper infraorbital hollows due to greater bone recession and thinner periorbital fat pads compared to female patients. Our doctors adjust injection depth, volume, and placement to achieve a subtle, natural correction that maintains strong facial structure — never an overfilled or feminised appearance.

The Micro-Cannula Safety Protocol

At PRP London Clinic, we exclusively use Teosyal Redensity II (teosyal tear trough) for infraorbital rejuvenation — a CE-marked Hyaluronic Acid gel specifically engineered for the delicate under-eye area. Unlike standard dermal fillers, Teosyal Redensity II combines 15mg/ml of cross-linked and non-cross-linked HA with a Dermo-Restructuring Complex of 14 essential nutrients, and features a phosphate buffer at pH 7.3 to minimise post-injection swelling.

To ensure maximum patient safety and minimise bruising, our doctors utilise the tear trough filler cannula technique. Instead of using a sharp needle near the eye, a blunt-tipped 25G micro-cannula is introduced via a single entry point on the lateral cheek. The cannula glides smoothly beneath the tissue in the supra-periosteal plane, safely bypassing blood vessels and nerves to deposit the HA gel deep along the orbital rim.

Typical treatment volumes range from 0.5ml to 1ml per eye (1–2ml total), with the exact amount determined by the severity of the tear trough deformity and the patient’s mid-face anatomy. The integrated lidocaine in Teosyal Redensity II provides built-in anaesthesia, making the procedure highly comfortable with a very low pain rating.

Step-by-Step: Your Tear Trough Filler Treatment

Our doctors follow a structured clinical protocol to ensure consistent, safe, and natural results for every tear trough filler london patient at 33 Cavendish Square.

1

Clinical Assessment & Facial Analysis

Your doctor conducts a thorough assessment of your infraorbital anatomy, mid-face volume, skin quality, and the underlying cause of your dark circles or hollowing. Photographs are taken under standardised lighting. If your under-eye concerns are caused by fat pad herniation or pigmentation rather than volume loss, your doctor will advise against filler and recommend an alternative approach.

2

Treatment Planning & Informed Consent

Based on the assessment, your doctor recommends the appropriate volume of Teosyal Redensity II, discusses the cannula technique, and explains expected outcomes, potential risks, and aftercare. Full informed consent is taken before proceeding.

3

Preparation & Anaesthesia

The under-eye and mid-cheek area is cleansed with antiseptic solution. A topical anaesthetic cream is applied to the cannula entry point on the lateral cheek for 15–20 minutes to ensure comfort.

4

Cannula Entry & Filler Placement

A small pilot hole is created on the lateral cheek using a fine needle, and the blunt-tipped 25G micro-cannula is introduced. The cannula glides in the supra-periosteal plane beneath the orbicularis oculi muscle, depositing Teosyal Redensity II in precise, controlled micro-deposits along the orbital rim and tear trough groove.

5

Contour Assessment & Symmetry Check

Your doctor assesses the result in real time, checking volume distribution, symmetry, and the smoothness of the lid-cheek junction from multiple angles. Minor adjustments are made to ensure a seamless, natural contour.

6

Aftercare Instructions

You receive detailed written aftercare guidance covering the first 48 hours and beyond. Cold compresses are applied to minimise immediate swelling. You are advised to avoid touching the area, strenuous exercise, and alcohol for 24–48 hours.

7

2-Week Review Appointment

All tear trough patients are invited back for a complimentary review appointment at 2 weeks. At this stage, any residual swelling has resolved and your doctor can assess the settled result. If a minor top-up is needed, it can be performed at this visit.

Fixing Botched & Migrated Tear Trough Filler

Because the skin under the eye is less than 0.5mm thick, poor injection technique by inadequately trained practitioners frequently results in a botched tear trough filler. We receive regular referrals from patients presenting with:

  • Tyndall Effect: A blue-grey discolouration caused by filler placed too superficially in the thin periorbital skin
  • Overfilling: An overfilled tear trough filler creates fluid retention, sausage-like lumps, and persistent puffiness that worsens the under-eye appearance
  • Migration: Tear trough filler migration occurs when the gel displaces from the tear trough groove down into the cheek or laterally into the malar region, creating visible ridges and contour irregularities
  • Malar Oedema: A filler under eye gone wrong can cause chronic waterlogging of the mid-face tissue, particularly when highly hydrophilic (water-attracting) fillers are used in this area

If you present to our clinic with a tear trough filler gone wrong, our medical team will provide an objective, honest assessment. Where indicated, we safely administer the prescription enzyme Hyaluronidase to completely dissolve tear trough filler. Once the old product has been metabolised and the tissue has settled (typically 14 days), we can discuss a safe, anatomically correct re-treatment plan using the appropriate low-hydrophilic filler and cannula technique.

Tear Trough Filler vs. Surgical Lower Blepharoplasty

Patients with under-eye hollowing often consider both non-surgical filler and surgical blepharoplasty. The right choice depends on the underlying anatomy, severity of concern, and desired permanence.

FactorTear Trough Filler (Non-Surgical)Lower Blepharoplasty (Surgical)
Procedure time30–45 minutes1–2 hours (general or local anaesthesia with sedation)
Downtime48–72 hours mild swelling/bruising2–4 weeks recovery; visible bruising for 10–14 days
ReversibilityFully reversible with HyaluronidasePermanent and irreversible
Longevity9–12+ monthsPermanent (10+ years)
Best forVolume loss, hollow tear troughs, shadow-based dark circlesExcess skin, bulging fat pads, severe skin laxity
Cannot addressTrue fat pad herniation, significant excess skinCannot add volume to hollow areas (may worsen hollowing)
Risk profileLower (no general anaesthesia, no incision, reversible)Higher (scarring, ectropion, dry eye, infection, asymmetry)
CostFrom £450 per session£3,000–£6,000+

Many patients choose tear trough filler as a non-committal first step — allowing them to see volume restoration results before considering whether surgical intervention is warranted. Our doctors will always provide an honest assessment of which approach is most appropriate for your anatomy.

Tear Trough Filler Cost London

Patients frequently ask how much is tear trough filler at our London clinic. The tear trough filler cost at PRP London Clinic starts from £450 per session, reflecting the use of Teosyal Redensity II — a premium, CE-marked HA filler specifically licensed for the periorbital region — alongside the clinical expertise of our GMC-registered doctors.

The total tear trough filler prices may vary depending on:

  • Volume required: Most patients require 0.5–1ml per eye (1–2ml total). Some patients with very deep hollows or significant mid-face volume loss may require additional filler
  • Mid-face support: If your cheeks lack structural volume, your doctor may recommend cheek filler as a foundation before treating the tear trough — this ensures the under-eye filler has adequate scaffolding and reduces the risk of migration
  • Complexity: Correction cases (dissolving previous filler before re-treatment) require additional appointments and Hyaluronidase

Your exact under eye filler cost london is confirmed during your in-person clinical assessment. We do not offer discounted or ‘cheap’ tear trough treatments — the periorbital region demands premium products and genuine medical expertise. All pricing includes your complimentary 2-week review appointment.

Safety Profile & Risk Management

The question is tear trough filler safe is one of the most important a patient can ask. The infraorbital region contains the infraorbital artery, angular artery branches, and infraorbital nerve. Intravascular injection can lead to serious complications including tissue necrosis and, in extremely rare cases, visual disturbance. A meta-analysis of 2,556 patients (Liu et al., 2024) demonstrated that when performed by experienced practitioners, HA tear trough injection achieves a 91% pooled satisfaction rate with a low overall complication profile.

Common side effects and their typical resolution:

  • Swelling/oedema: 19.2% incidence; typically resolves within 48–72 hours, occasionally persisting for up to 2 weeks
  • Bruising: 18.4% incidence; resolves within 5–10 days. Our cannula technique significantly reduces bruising compared to needle injection
  • Contour irregularity: 5.3% incidence; usually self-resolves or is addressed at the 2-week review
  • Tyndall effect: 0.9% incidence; caused by superficial filler placement — avoided by our supra-periosteal cannula protocol

Our clinic-specific safety measures include:

  • Exclusive Micro-Cannula Protocol: Blunt-tipped cannulas navigate around blood vessels rather than through them, dramatically reducing vascular risk
  • Supra-Periosteal Placement: Filler is deposited deep on the bone, minimising Tyndall effect and contour irregularities
  • Emergency Preparedness: All treatment rooms at 33 Cavendish Square are equipped with Hyaluronidase for immediate vascular rescue, alongside the full complement of medical emergency equipment
  • Conservative Volume Protocol: Maximum 1ml per eye per session, with top-ups at the 2-week review rather than risking overfilling

Post-Treatment Aftercare & Recovery

Proper aftercare following your tear trough filler london treatment is essential to optimise results and minimise complications. Your doctor provides detailed written aftercare instructions at the end of every appointment.

First 24–48 Hours

  • Apply cold compresses gently (not ice directly on skin) to the under-eye area for 10 minutes at a time to reduce swelling
  • Avoid touching, pressing, or massaging the treated area — the filler needs time to integrate with the tissue
  • Sleep on your back with your head slightly elevated to reduce fluid accumulation
  • Avoid strenuous exercise, saunas, steam rooms, and hot baths
  • Do not consume excessive alcohol, which can increase bruising
  • Avoid blood-thinning supplements (fish oil, vitamin E, aspirin) unless medically prescribed

First 2 Weeks

  • Avoid wearing heavy glasses or sunglasses that press on the tear trough area, as sustained pressure can indent settling filler
  • Avoid facials, chemical peels, or laser treatments on the periorbital area
  • Do not fly within 48 hours of treatment (cabin pressure changes can increase swelling)
  • Mild swelling may fluctuate — tear trough filler swelling stages typically progress from initial puffiness (days 1–3) to gradual settling (days 4–10) to final result (day 14+)

2-Week Review

All tear trough patients are invited back for a complimentary review appointment at 2 weeks. By this stage, swelling has fully resolved and your doctor can assess the settled result. If a minor asymmetry correction or top-up is needed, it can be performed at this visit.

Am I a Good Candidate for Tear Trough Filler?

Ideal CandidateMay Need an Alternative Approach
Dark circles caused by structural hollowing and shadowsDark circles caused by hyperpigmentation or visible vascular networks (filler will not resolve skin colour)
Visible tear trough groove or infraorbital hollowingProminent bulging fat pads (malar bags) — filler may exacerbate puffiness; surgical assessment recommended
Adequate mid-face (cheek) volume to support the under-eyeSignificant cheek volume loss — may require cheek filler as a foundation before tear trough treatment
Healthy adult with no active periorbital skin infectionsActive infection, eczema, or inflammation in the under-eye area
Realistic expectations about subtle, natural correctionExpecting filler to completely eliminate genetic dark circles, loose skin, or deep wrinkles
Willing to attend the 2-week review and maintain with annual top-upsNot willing to commit to periodic maintenance treatments (surgical blepharoplasty may be more appropriate)
Seeking non-permanent, fully reversible enhancementWanting a permanent, one-time solution (lower blepharoplasty)

Contraindications: Who Should Not Have Tear Trough Filler?

Patient safety is our primary clinical directive. Our doctors will decline to treat patients who present with specific contraindications for tear trough fillers:

  • Bulging Fat Pads (Malar Bags): If your under-eye bags are caused by herniated orbital fat rather than volume loss, injecting HA filler will only exacerbate the puffiness. These patients require surgical assessment for fat repositioning or removal.
  • Severe Skin Laxity: Patients with significant excess skin in the lower eyelid will not achieve satisfactory results with filler alone. Skin tightening or surgical intervention is more appropriate.
  • Hyperpigmentation-Only Dark Circles: If dark circles are caused strictly by melanin deposits or visible blood vessels (not structural shadows), filler will not resolve the discolouration. Topical treatments, chemical peels, or laser therapy are more appropriate.
  • Active Periorbital Infection: Any active infection, cold sore, or inflammatory condition near the injection site is an absolute contraindication until fully resolved.
  • Pregnancy or Breastfeeding: HA fillers are not safety-tested in pregnant or breastfeeding patients. Treatment is postponed.
  • Autoimmune Connective Tissue Disorders: Conditions such as lupus or scleroderma may increase the risk of inflammatory reactions to injectable HA.
  • Known Hypersensitivity: Any previous allergic reaction to Hyaluronic Acid products or Lidocaine.

If you are contraindicated for tear trough filler, our doctors will discuss appropriate alternatives such as polynucleotide under-eye treatment or PRP for under eyes to address your concerns through a different mechanism.

Book Your Clinical Assessment

Refresh your tired eyes safely. Book a clinical assessment at 33 Cavendish Square with Dr Bruno Amendola, Dr Mohamed Nafei, or Dr Reem Nouri to determine if Teosyal Redensity II tear trough filler is the optimal solution for your under-eye concerns. Our approach is always conservative — we will never recommend treatment that is not in your clinical best interest.

Myths vs Facts

M

Tear trough filler will cure all types of dark circles.

F

Filler only corrects dark circles caused by structural shadows from infraorbital hollowing. If your dark circles are caused by hyperpigmentation (melanin deposits) or visible vascular networks beneath the skin, our doctors will recommend alternative treatments such as polynucleotides or PRP instead of filler.

M

Tear trough filler always causes black eyes and severe bruising.

F

While bruising is a risk with any injection, our doctors’ exclusive use of blunt-tipped micro-cannulas significantly reduces the risk of piercing blood vessels. A meta-analysis of 2,556 patients found bruising occurred in 18.4% of cases — meaning the majority of patients experience zero or minimal bruising, particularly with cannula technique.

M

The filler will make my under-eyes look puffy and swollen permanently.

F

Puffiness only occurs when incorrect, highly hydrophilic (water-attracting) fillers are used, or when filler is injected too superficially or in excessive volumes. Teosyal Redensity II is specifically formulated with low hydrophilicity and a pH-buffered formula to minimise swelling when placed deep in the supra-periosteal plane.

M

Anyone can safely inject tear trough filler — it’s a simple procedure.

F

The infraorbital region is one of the highest-risk areas in facial aesthetics due to its complex vascular network (infraorbital artery, angular artery branches) and the extreme thinness of the overlying skin. This treatment demands genuine medical expertise, detailed anatomical knowledge, and experience with periorbital injection — it should only be performed by a qualified, GMC-registered doctor.

M

Tear trough filler looks unnatural when you smile.

F

When correctly placed in the supra-periosteal plane (deep on the bone), tear trough filler maintains a natural appearance in all facial expressions, including smiling. Unnatural appearance typically results from superficial placement or overfilling — both avoidable with proper technique and conservative volumes.

Frequently Asked Questions

Patients frequently ask our medical team is tear trough filler safe. The infraorbital region is a high-risk injection zone due to its complex vascular network. However, a meta-analysis of 31 studies involving 2,556 patients (Liu et al., 2024) demonstrated a 91% satisfaction rate with a low overall complication profile when performed by experienced practitioners. Our GMC-registered doctors exclusively use micro-cannula technique in the supra-periosteal plane, combined with conservative volumes, to maximise safety.
The tear trough filler cost london at PRP London Clinic starts from £450 per session using Teosyal Redensity II — a premium, CE-marked HA filler specifically formulated for the periorbital region. Your exact cost depends on the volume required and whether mid-face (cheek) support is needed as a foundation. A complimentary 2-week review appointment is included in all treatment pricing.
Patients often ask how long do fillers last under eyes. The under-eye area is relatively static, meaning it experiences minimal muscle movement compared to areas like the lips. HA filler degrades very slowly here, with clinical results typically enduring for 9 to 12 months, and frequently longer. A PRISMA systematic review (Trinh et al., 2022) found effect duration ranging from 8 to 12 months across 23 studies.
The procedure is surprisingly comfortable. Our cannula technique requires only a single entry point on the lateral cheek, which is numbed with topical anaesthetic before a small pilot hole is created. The blunt-tipped micro-cannula then glides smoothly under the skin without the sharp pain of repeated needle punctures. Teosyal Redensity II also contains integrated lidocaine (0.3%) for built-in anaesthesia as it is injected.
What is tear trough filler is one of the most common questions we receive. It is a non-surgical medical procedure where a specially formulated Hyaluronic Acid gel (in our case, Teosyal Redensity II) is injected into the infraorbital groove — the hollow area beneath the eye known as the tear trough — to restore lost volume, smooth the under-eye contour, and eliminate structural shadows that cause dark circles.
Patients concerned about tear trough filler smiling appearance can be reassured: when correctly placed in the supra-periosteal plane (deep on the bone, beneath the orbicularis oculi muscle), the filler integrates seamlessly with your natural anatomy. It maintains a natural look during all facial expressions including smiling, laughing, and squinting. Unnatural appearance typically results from superficial placement or overfilling — both avoided by our conservative cannula protocol.
A tear trough filler gone wrong can manifest as Tyndall effect (blue-grey discolouration), persistent puffiness, contour irregularities, or filler migration. The reassuring advantage of HA filler is that it is fully reversible — Hyaluronidase enzyme can be administered to completely dissolve the product. At PRP London Clinic, we regularly treat patients presenting with botched work from other clinics, dissolving the old filler and performing safe corrective re-treatment after a 14-day recovery period.
The tear trough is structurally supported by the mid-face (the cheek). If you have significant volume loss in your cheeks, injecting the under-eye without first rebuilding the cheek’s structural scaffolding can lead to poor results and potential tear trough filler migration. During your consultation, your doctor will assess whether cheek fillers are needed as a foundation before treating the tear trough.
Patients searching for under eye filler for wrinkles should understand that while filler alone cannot erase established wrinkles, restoring volume to a hollowed tear trough can significantly improve the appearance of fine lines and crepey skin in the periorbital area. Teosyal Redensity II’s Dermo-Restructuring Complex — containing amino acids, antioxidants, and minerals — also supports dermal quality alongside volumisation.
Understanding tear trough filler swelling stages helps manage expectations: Days 1–3 typically involve the most noticeable swelling and potential mild bruising. Days 4–7 see significant swelling reduction, though the under-eye area may still appear slightly fuller than the final result. Days 7–14 show continued settling, with the filler integrating into the tissue. By day 14, the final result is visible — which is why we schedule your review appointment at the 2-week mark.
Male tear trough filler is one of the most requested treatments among our male patients. Men typically present with deeper infraorbital hollows due to greater bone recession and thinner periorbital fat pads. Our doctors adjust injection technique to achieve a subtle, natural correction that maintains masculine facial structure — refreshing tired-looking eyes without an overfilled or feminised appearance.
Yes — one of the key advantages of HA-based tear trough filler is full reversibility. If you wish to dissolve tear trough filler for any reason (dissatisfaction, migration, or complications), the prescription enzyme Hyaluronidase can be administered to break down the HA gel completely. At our clinic, dissolution is performed by a GMC-registered doctor, and the area is allowed to settle for 14 days before any corrective re-treatment is considered.
We exclusively use Teosyal Redensity II for tear trough treatment — a CE-marked HA filler specifically engineered for the periorbital region. Its low hydrophilicity (low water-attracting properties) minimises post-treatment puffiness, while its 14-nutrient Dermo-Restructuring Complex supports skin quality. Unlike standard volumising fillers used in the cheeks or jawline, Redensity II is designed for the unique demands of the ultra-thin under-eye skin.
Typical treatment volumes range from 0.5ml to 1ml per eye (1–2ml total between both eyes), depending on the severity of the hollowing and your mid-face anatomy. A prospective study (Diwan et al., 2020) confirmed that a maximum of 1ml between both eyes per session is a safe protocol. Our doctors follow a conservative approach — it is always safer to add a small top-up at the 2-week review than to overfill at the initial appointment.
