Quick answer: Tear trough filler fills the hollow under your eyes. The result is a smoother, brighter under-eye area. Results show up right away and settle within 1 to 2 weeks. They last 9 to 18 months. This is one of the most precise filler treatments available. Published research shows a 91% patient satisfaction rate.
What is tear trough filler before and after? Tear trough filler before and after shows what changes after filler is injected under the eye. The hollow groove from the inner eye toward the cheek gets filled in. Before treatment, the area looks sunken and dark. After treatment, the skin sits smooth and even. The face looks rested.
This guide is based on two peer-reviewed studies and a clinical safety trial on tear trough filler. Cost data comes from US aesthetic practices in 2026.
Why tear trough hollowing happens
The tear trough is a natural groove under the eye. In youth, fat pads in the lower eyelid keep this groove shallow. The skin looks smooth from lid to cheek. As we age, those fat pads thin and drop. A hollow forms. Some people see this in their 20s due to genetics.
The hollow creates a shadow. Light can't reflect off a sunken surface the same way it reflects off flat skin. So the area looks dark. Most people mistake this for dark circles. But it's not about pigment — it's about shape.
Eye cream, sleep, and concealer can't fix this. They don't fill the hollow. Hyaluronic acid filler placed under the eye does. It restores lost volume and lifts the skin back to its natural shape.

What does tear trough filler before and after look like?
The change is subtle but clear. The goal isn't to erase the tear trough. It's a natural part of the face. The goal is to restore it to how it looked before volume was lost.
Right after treatment: The hollow fills in. The transition from lower lid to cheek looks smoother. Bruising and mild swelling are common in the first day or two. These don't reflect the final result.
After 1 to 2 weeks: The swelling goes down. The filler settles into place. The under-eye area looks brighter. Dark circles from shadowing reduce. The face looks more rested.
What patients say most: They look like they slept well. People notice the change but can't name it. Many say it's the best treatment they've had for the results it gives.
What filler won't do: It won't lift loose skin. It won't fix dark circles caused by pigment. It won't treat puffy under-eye bags. Those issues need a different approach.
What results are realistic — and what are not
| Concern | Tear Trough Filler Helps | Tear Trough Filler Does Not Help |
|---|---|---|
| Under-eye hollowing | Yes — fills the hollow directly | |
| Dark circles from shadows | Yes — reduces shadow by lifting the hollow | |
| Dark circles from pigmentation | No — pigment does not respond to filler | |
| Under-eye puffiness (fat bags) | No — may make bags look worse | |
| Fine lines on eyelid skin | Indirectly, by lifting the tissue | Not a direct fix for lines |
| Sagging lower eyelid skin | No — needs surgery | |
| Sunken cheek adding to hollow | Yes, if mid-face filler is added |
Good candidate screening matters here more than with most fillers. An injector who skips this step gets poor results. If you have puffy bags under your eyes, an oculoplastic surgeon may be a better fit than an injector.
The Makeover Tear Trough Candidacy Framework
Not everyone is a good fit for tear trough filler. Use this table to check if your concern is likely to respond well.
| Assessment Factor | Good Candidate | Poor Candidate |
|---|---|---|
| Cause of dark circles | Shadow from hollow | Pigment or visible blood vessels |
| Under-eye fat pads | Flat or minimal | Puffy or prominent bags |
| Skin thickness | Medium to thick | Very thin skin |
| Skin firmness | Firm, minimal loose skin | Loose or crepey lower eyelid |
| Age | Any — volume loss is the issue | Not age-based, anatomy-based |
| Anatomy | Hollow visible at rest | Fat bags more prominent than the hollow |
How to use this: Count your Good Candidate matches. Four or more means you're a strong candidate. Two or fewer means you should consult an injector about whether filler, surgery, or a mix is right for you.
Before your consultation, use Makeover.so to preview your result. Bring that image to your injector. It helps them understand exactly what you want.
How long does tear trough filler last?
Tear trough filler lasts longer than most other filler treatments. The under-eye area doesn't move much. This means hyaluronic acid breaks down at a slower rate.
A Journal of Clinical and Aesthetic Dermatology retrospective study found strong results at 18 months. Outcomes at 6, 12, and 18 months were largely the same.
A PubMed systematic review and meta-analysis looked at 2,556 patients across 31 studies. It found a 91% patient satisfaction rate. Average treatment duration was 10.8 months. Most patients need one top-up per year. The American Society of Plastic Surgeons' annual statistics provide broader context on filler use trends.
Key factors that affect how long results last:
- Metabolism: Fast metabolisers break down filler sooner. Active patients may need earlier top-ups.
- Volume placed: A slightly higher fill (within safe limits) extends the effect.
- Product choice: Thicker HA products like Restylane Lyft last longer under the eye.
- Lifestyle: Sun exposure, smoking, and poor skin health speed up filler breakdown.
What are the risks of tear trough filler?
The under-eye area carries the highest risk of any filler treatment zone. This doesn't mean you should avoid it. It means you must choose your injector with care. Read the FDA's guidance on dermal fillers before your consultation.
A PMC prospective safety study tracked side effects in tear trough patients:
- Bruising: 75% of patients — resolves in 5 to 10 days
- Swelling: 26% of patients — resolves within 1 week
- Lumpiness: 33% — clears with massage or dissolving
- Tyndall effect (blue-gray skin tone): 4% — caused by filler placed too close to the surface; treated with hyaluronidase
The most serious risk is vascular occlusion. This is when filler blocks a blood vessel. It is rare. But it can damage tissue if not caught fast. Injectors must keep hyaluronidase on hand at every appointment.
What to look for in your injector:
- Uses a cannula (blunt tip) rather than a sharp needle alone
- Keeps hyaluronidase at every session
- Reviews your anatomy and flags any risks before treatment
- Never skips numbing cream or rushes the consult
This treatment requires a trained medical provider with specific periorbital injection experience. The eye area has dense blood vessels and a small margin for error.
How much does tear trough filler cost in 2026?
Per Healthline's cost overview, one syringe of hyaluronic acid filler costs $684 to $1,500. Most tear trough cases use 0.5 to 1 syringe per side. RealSelf's tear trough ratings show verified patient reviews and worth-it scores from real cases.
| Cost Factor | Typical Range (US, 2026) |
|---|---|
| Cost per syringe (HA filler) | $684 – $1,500 |
| Volume needed per treatment | 0.5 – 1 syringe each side |
| Total treatment cost | $800 – $2,500 |
| Maintenance (annual) | $600 – $1,200 |
Less filler is used here than in the cheeks or lips. But the skill required is high. Pricing reflects the injector's experience, not just product volume.
Don't pick an injector on price alone. Fixing a vascular issue or Tyndall effect costs more than any savings from a cheaper session.

How to preview your tear trough filler result before treatment
Tear trough filler gives one of the clearest results of any non-surgical treatment. But many patients arrive with ideas that don't match what filler can do. A preview changes that.
We built Makeover.so for this. Upload a photo of your face. Pick the under-eye filler preview. Our AI fills in the hollow on your actual photo. You see what your under-eyes could look like — in under 10 seconds.
Not sure if you need filler or surgery? A Makeover preview shows the filler result before any consultation. For injectors, it's a powerful tool. Showing patients their own result in advance builds trust and sets shared goals before the first syringe is opened.

Choosing the right injector
Only a trained medical provider should perform tear trough filler. In the US, this means a physician, nurse practitioner, or registered nurse with proven periorbital injection experience. Use the American Board of Cosmetic Surgery's Find a Surgeon directory to check board certification before you book.
Questions to ask before booking:
- How many tear trough cases do you do each month?
- Do you use a cannula, a needle, or both — and why?
- Do you have hyaluronidase on-site?
- Can I see before-and-after photos of cases like mine?
- What is your plan if I get bruising, lumps, or discolouration?
Combining with other treatments:
Many patients get better results when tear trough filler is paired with mid-face filler. Cheek volume lifts the tissue from below and supports the under-eye result. Our jawline filler before and after guide covers this structural approach in detail.
A good injector looks at your full mid-face, not just the hollow under your eye.
