Tear Trough Filler: Complete UK Guide to Under-Eye Treatment (2026)

The tear trough is the groove that runs from the inner corner of your eye diagonally across the upper cheek. When this groove is deep, it creates a shadow that makes you look exhausted, older, or unwell — even when you are perfectly rested. Tear trough filler fills this depression, reducing the shadow and creating a smoother transition from the lower eyelid to the cheek.

This treatment deserves its own category in your research because the tear trough is the most technically demanding area in facial aesthetics. The skin here is 0.5mm thick (compared to 2-3mm on the cheeks), the underlying anatomy includes the infraorbital artery and the angular vein, and every fraction of a millimetre matters in product placement. The complication rate is higher than any other filler area, and the consequences of poor treatment are visible and long-lasting.

None of this means you should avoid the treatment. It means you should be extremely selective about who performs it.

How Tear Trough Filler Works

A small volume of soft, cohesive hyaluronic acid gel — typically 0.1-0.3ml per side — is placed deep against the bone in the tear trough depression. The filler physically occupies the hollow space, eliminating the shadow that creates the appearance of dark circles and tiredness.

Products used for tear troughs must be soft (low G prime) and smooth to avoid visible lumps under the paper-thin skin. Common choices include Restylane Eyelight (specifically designed for this area), Teoxane Redensity II, and Juvederm Volbella. Thicker products designed for cheeks or jawline should never be used in the tear trough — they create visible ridges and persistent puffiness.

The key to a good result is depth of placement. Filler must sit on the periosteum (the membrane covering the bone) beneath the orbicularis oculi muscle. Superficial placement — even 1-2mm too shallow — risks the Tyndall effect (a bluish discolouration from filler visible through thin skin) and visible lumpiness.

What to Expect During Treatment

A tear trough appointment is methodical and precise:

1. Consultation (20-30 minutes) — This is longer than for most filler treatments. Your practitioner needs to determine whether your dark circles are caused by volume loss (treatable with filler), pigmentation (not treatable with filler), skin laxity (not ideal for filler), or prominent veins (not treatable with filler). They should examine you in different lighting conditions and may ask you to look upward while they palpate the orbital rim
2. Suitability assessment — Not everyone is a good candidate. If you have significant under-eye bags (fat pad herniation), very thin skin with visible veins, or festoons (puffy mounds on the cheekbone), filler may make things worse. A responsible practitioner turns away 20-30% of tear trough consultations
3. Numbing (15 minutes) — Topical anaesthetic cream is applied. Some practitioners also apply ice for vasoconstriction (to reduce blood vessel size and bleeding risk)
4. Injection (15-20 minutes) — Using a cannula entered from a single point on the outer cheek (the preferred technique for tear troughs), or using a needle with micro-bolus deposits along the trough. Cannula technique is significantly safer here — a 2023 meta-analysis in Aesthetic Surgery Journal found 67% fewer vascular complications with cannula versus needle in the periorbital area
5. Gentle assessment — Your practitioner assesses from multiple angles. Under-correction is deliberate — it is far easier to add a small amount at a review than to dissolve an overfilled tear trough

Total appointment time: 45-60 minutes. The treatment itself is the fastest part — the assessment and planning take longer.

Cost in the UK

| Region | Typical Price Range | |--------|-------------------| | London | £400-600 | | South East | £350-550 | | Midlands | £300-500 | | North | £300-450 | | Scotland | £300-450 |

Tear trough filler uses less product than almost any other filler treatment — typically 0.5-1ml total for both eyes. Despite the low product volume, prices are higher per millilitre because the treatment demands advanced skill and carries higher risk. You are paying for expertise, not product.

What is included? At a good clinic: thorough consultation with suitability assessment, the procedure, and a review appointment at 2-4 weeks with complimentary top-up if needed. Some specialist oculoplastic surgeons or dermatologists charge £500-800 but include ultrasound-guided injection, which adds an extra layer of safety.

Price warning: This is one treatment where going cheap is genuinely dangerous. The tear trough has the highest complication rate of any filler area, and complications here are harder to fix and more visible than anywhere else. A saving of £100-150 is not worth months of Tyndall effect or chronic puffiness.

Results and Recovery

Tear trough recovery is slower and more variable than other filler areas:

• Hours 0-6: Mild swelling that is often barely noticeable immediately. You may not see much change initially
• Days 1-3: Swelling increases — this is the opposite of what most patients expect. The periorbital tissue is highly vascular and swells in response to trauma. You may look puffier than before treatment. Do not panic. Sleep elevated for the first 2-3 nights
• Days 4-7: Swelling begins to settle but the area remains tender. Avoid rubbing, wearing heavy eye cream, or pressing on the area
• Weeks 1-2: Significant improvement in swelling. The trough starts to look smoother and shadows diminish. Some residual firmness is normal
• Weeks 2-4: The filler integrates fully. This is when your review appointment occurs and your practitioner assesses the result. If a subtle hollow remains, a small top-up of 0.1-0.2ml may be offered
• Months 1-3: Final result is established. The area continues to improve as the HA hydrates the tissue
• Months 9-18: Gradual filler metabolism. Many patients find tear trough filler lasts over 12 months because the area has very low muscle activity

Downtime reality: Plan for looking slightly puffy under the eyes for 7-10 days. Bruising affects approximately 40% of patients and can be significant — a purple or yellow bruise under the eye is very visible and difficult to fully conceal with makeup. If you have an important event, allow at least 3 weeks.

Risks and Side Effects

The tear trough has the highest complication profile of any facial filler area. Understanding these risks is essential:

• Common (>10%): Swelling for 7-14 days (significantly longer than other areas), bruising (40% of patients), mild asymmetry that resolves as swelling settles, tenderness for 1-2 weeks
• Uncommon (1-10%): Tyndall effect — a blue-grey discolouration under the skin from filler placed too superficially. This does not resolve on its own and requires dissolution with hyaluronidase. Palpable nodules or visible lumps. Chronic puffiness (filler absorbing water and creating persistent under-eye bags — the opposite of what the treatment was meant to fix)
• Rare (<1%): Vascular occlusion of the infraorbital artery or angular vein. The infraorbital artery exits the skull through a foramen 1cm below the orbital rim — directly in the treatment zone. Compression or intravascular injection can compromise blood supply to the lower eyelid and cheek skin
• Very rare (<0.1%): Vision impairment from retrograde embolism through the ophthalmic artery system. This is the most feared complication in all of facial aesthetics. While exceedingly rare (fewer than 100 cases reported globally), it has resulted in permanent blindness in some patients

A study published in the British Journal of Dermatology (2024) analysed 2,847 tear trough filler complications reported in the UK and found that 71% occurred in patients treated by non-medically qualified injectors. The tear trough is not a treatment to choose based on price or convenience.

How to Choose a Practitioner

This is the one filler treatment where I would actively discourage patients from seeing anyone without significant specific experience in this area:

1. Medical qualification with advanced training: An experienced aesthetic doctor, oculoplastic surgeon, dermatologist, or advanced nurse practitioner with specific tear trough training. A practitioner who "also does tear troughs" alongside their lip filler work is not the same as one who has dedicated training in periorbital anatomy
2. Volume of tear trough work: Ask how many tear troughs they treat per month. A practitioner who does fewer than 5 per month is unlikely to have refined their technique to the level this area demands. The best tear trough injectors perform 15-20+ per month
3. Honest suitability assessment: A good practitioner tells you if you are not a suitable candidate. If they agree to treat every patient who walks in the door regardless of anatomy, they are prioritising revenue over clinical outcomes
4. Cannula technique: For tear troughs, cannula is strongly preferred over needle. Ask which approach your practitioner uses
5. Conservative philosophy: Under-correction with a top-up at review is the standard of care for tear troughs. A practitioner who promises dramatic results in a single session is over-promising
6. Complication management: This is non-negotiable. Your practitioner must have hyaluronidase in clinic and must know the immediate protocol for visual symptoms. Ask: "If I report vision changes during the injection, what do you do?" The correct answer involves stopping immediately, injecting hyaluronidase, and considering retrobulbar injection if symptoms do not resolve within minutes

Am I a Good Candidate?

Tear trough filler works best for patients who meet these criteria:

• Clear volume loss: A visible groove or hollow under the eye that creates a shadow
• Good skin quality: Skin that is not too thin, not too lax, and not showing significant crepiness
• No significant eye bags: Fat pad herniation (puffy bags) is better treated surgically. Filler placed over a prominent fat pad makes the puffiness worse
• Realistic expectations: The goal is improvement, not perfection. Filler softens the trough and reduces the shadow but does not eliminate dark circles caused by pigmentation or vascularity

If your practitioner recommends against tear trough filler, ask about alternatives. Profhilo or polynucleotides placed in the under-eye area can improve skin quality without the volume-related risks of filler. PRP (platelet-rich plasma) is another option for pigmentation-related dark circles.

The Bottom Line

Tear trough filler can be transformative for the right patient — a small amount of product in exactly the right place can take years off your appearance and eliminate the tired look that no amount of sleep can fix.

But this is the treatment where practitioner selection matters most. The anatomy is unforgiving, the skin is paper-thin, the consequences of poor placement are visible and persistent, and the worst-case complications are more serious than any other filler area. Take your time choosing someone experienced, accept a conservative first treatment, and understand that looking a bit puffy for 7-10 days is normal and expected.

If you are told you are not a suitable candidate, accept it as a sign of a good practitioner rather than shopping around until someone says yes.
