Tear Trough Filler (Under-Eye Filler) in Australia: Cost, Risks and Results

Tear trough filler, also called under-eye filler, is one of the more technically demanding cosmetic injections a practitioner can perform, not because the injection itself is difficult, but because the area sits directly on a network of blood vessels connected to the eye itself. Done well, it is one of the more transformative, natural-looking treatments available. Done carelessly, it carries the single most serious complication in all of cosmetic filler. This guide covers both sides properly: what it actually fixes, what it does not, and the real risk profile most clinic websites underplay.

Tear trough filler in Australia typically costs $600 to $1,500 per treatment, using a small amount, usually under half a millilitre per side, of a soft hyaluronic acid filler specifically chosen for this thin-skin area. Results commonly last 9 to 18 months. It only helps one specific cause of under-eye darkness, a genuine hollow or shadow from volume loss, and does essentially nothing for dark circles caused by pigmentation, which is a distinction worth understanding before you book.

What is actually causing the hollow under your eyes

The “tear trough” is the groove that runs from the inner corner of your eye out toward your cheek, formed where the lower eyelid meets the cheek. An authoritative anatomical source describes it as “a hollowed and sunken area in the skin between the lower eyelid and the cheekbone,” noting it “can occur due to inherited anatomical differences or aging.” Underneath it sits a genuinely complex structure: skin with almost no fat cushioning of its own, the orbicularis oculi muscle, a band of connective tissue called the tear trough ligament, and pockets of fat that, with age, herniate or drop as the ligament holding them in place weakens.

Crucially, not every case of under-eye darkness has the same cause, and filler only helps one of them. Peer-reviewed clinical literature splits the causes into three genuinely different categories: a structural shadow from volume loss and hollowing, a vascular type where thin skin simply shows the blood vessels underneath more clearly, and a pigmentary type caused by excess melanin, sun damage or conditions like melasma. The first step in properly treating under-eye darkness, according to a published clinical review, is to “identify the specific constellation of aetiologic factors present so that a customised therapy can be crafted.”

What kind of filler is actually used here

Hyaluronic acid is the standard substance, the same reversible filler family covered in our lip filler guide, used for lips and cheeks, but the specific type matters more here than almost anywhere else on the face. Practitioners deliberately choose a soft, low-viscosity formulation for the tear trough rather than the thicker, firmer gel often used to build cheek volume. Published clinical research explains why directly: firmer, higher-viscosity gels “may be more likely to cause malar edema,” the swelling complication covered in detail further down this guide, while a softer gel absorbs less water and sits more predictably in an area with almost no fat cushioning of its own to hide behind.

In 2023, this became specific enough that a filler was formally approved in the United States for exactly this use. Restylane Eyelight is, per its manufacturer, “the first and only product in the U.S. formulated with NASHA Technology for volume loss under the eyes,” approved specifically “for the treatment of undereye hollows, also known as dark shadows.” Its clinical trial reported 87 percent of patients with reduced hollowing at three months, and 84 percent still satisfied with their result at the one-year mark, with the trial recording no cases of the blue-grey discolouration covered later in this guide. We were not able to confirm whether this specific product is currently registered on Australia’s Therapeutic Goods Register, so do not assume it is available locally without checking with your practitioner directly; most Australian clinics use other established soft hyaluronic acid fillers for this area regardless.

How much tear trough filler costs in Australia

No government body publishes official pricing, since this is a cosmetic procedure with no Medicare coverage. Every figure below comes from surveying current Australian clinic pricing, which varies more than you might expect depending on how a clinic packages the treatment.

The injection technique

This is one of the few facial areas where using a blunt-tipped cannula rather than a sharp needle is genuinely, strongly preferred by clinical guidance, not simply a matter of injector style. A clinical safety guideline on avoiding vision-threatening complications specifically names the tear trough as an area where cannula use is recommended, and published research on this area states plainly that cannula use “reduces the risk of vascular occlusion.” A blunt cannula tip tends to push blood vessels aside rather than pierce them, which matters enormously given the vascular network sitting directly beneath this area, covered in detail in the next section.

Most published technique protocols place the filler deep, in the plane directly against the bone beneath the muscle, rather than closer to the surface. This deeper placement serves two purposes: it keeps the product away from the very thin skin above, reducing the risk of visible lumps or a blue-grey discolouration, and it is the plane most consistently described across published surgical technique papers, though a minority of protocols use a slightly more superficial plane instead.

The most serious risk: vascular occlusion and vision loss

This is the part of this guide we will not soften, because it deserves to be understood clearly rather than buried in fine print. The tear trough sits directly above a network of connected blood vessels, including the infraorbital and angular arteries, which link through a chain of smaller vessels to the ophthalmic artery, the artery that supplies the eye itself. Published anatomical research explains the mechanism directly: “injecting into the infraorbital artery creates a potential pathway to the ophthalmic artery, due to its connection to the supraorbital and supratrochlear vessels. Retrograde migration along these routes can embolize the ophthalmic artery, causing blindness.” In plain terms, if filler is accidentally injected into the wrong vessel, it can travel backward through this network and block blood flow to the eye itself.

How often does this actually happen? A landmark review of the world’s published literature identified 98 documented cases of vision change from filler injection across all facial areas combined, with the glabella, between the eyebrows, and the nose responsible for the clear majority, roughly two in three cases between them. The tear trough itself was not among the leading sites in that dataset, though it sits anatomically on the same connected vascular network. A more recent 2025 review put the global cumulative case count at roughly 170, with only around one in five affected patients recovering their vision. No study has ever calculated a true incidence rate, the percentage chance per injection, because these are pooled case reports rather than a tracked denominator of every treatment performed; what is clear is that this is a real, if rare, catastrophic risk rather than a theoretical one.

This is also the clearest reason cannula technique is so strongly favoured for this area, covered in the previous section, and why an experienced injector will use small volumes, low injection pressure, and careful technique specifically designed to avoid ever entering a vessel in the first place. The overwhelming majority of tear trough treatments are performed without any vascular complication at all, but this is precisely the risk that separates an experienced, properly trained injector from someone simply offering the treatment cheaply.

Malar edema: the swelling that can turn up years later

This is a genuinely area-specific complication, and it is common enough to deserve its own explanation. Published research puts the rate at up to 11 percent of tear trough filler cases over long-term follow-up, with some individual studies reporting higher rates depending on technique and volume used. The mechanism is architectural: a fascial structure called the malar septum sits just below the tear trough and acts as a barrier, and published research explains that “excessive volume or more elastic product in the superficial compartment can compress lymphatics and compromise drainage, leading to malar edema.”

What makes this complication unusual is its delayed timing. Hyaluronic acid is hygroscopic, meaning it draws in water, and as the filler gradually breaks down over months or years, published research notes it “can begin to absorb more water as it slowly de-polymerizes into smaller constituents.” That means genuine puffiness can appear well after your initial treatment looked settled and fine, sometimes years later, trapped above the malar septum with nowhere to drain. The good news is that it is manageable: published clinical guidance describes treating it with hyaluronidase, sometimes followed by a different, softer filler at a later date if you want the area re-treated.

The Tyndall effect: why this area is prone to a blue-grey tinge

Because the skin here is genuinely thin, with almost none of the fat layer that hides superficial filler placement elsewhere on the face, this is one of the more common areas for a specific optical phenomenon called the Tyndall effect. Published explanation: “blue light scatters to a larger degree than other colours of light with longer wavelengths when passing through small particles, such as HA. Thus, if too much HA is placed too superficially, a blue-grey discolouration can occur even without lumps.” One real-world clinical study recorded this in roughly 3 percent of patients, though the rate varies by product and technique, and a separate clinical trial using a specifically low-viscosity product designed for this area recorded no cases of it at all.

How long tear trough filler lasts

Most patients can expect somewhere between 9 and 18 months, and this area does not appear to wear off faster than other filler sites despite the constant movement of blinking, contrary to what you might assume. A published anatomical review puts the average improvement at “approximately 9 to 12 months,” while a systematic review pooling more than 2,000 patients found subjective results lasting an average of close to 11 months, with objective imaging showing 85 percent of the correction still present at 15 months in some patients. Firmer, longer-lasting formulations have been reported lasting up to 23 months in some studies, and the FDA-approved product specifically designed for this area claims results up to 18 months. As with most filler areas, expect a genuine range rather than one fixed number, and know that a softer, area-appropriate product may not last quite as long as a firmer one used elsewhere on the face, a reasonable trade-off given the lower complication risk it carries here.

When filler is not the right treatment

Filler adds volume. It cannot remove or reduce fat, and it cannot tighten skin. This matters because a genuinely common under-eye concern, bulging fat pads or “eye bags,” is a different problem entirely to the hollow this treatment addresses, and filler is the wrong tool for it. Clinicians use grading systems, commonly the Hirmand and Barton scales, to separate milder cases, better suited to filler, from more significant hollowing or genuine fat herniation, better suited to surgery. Published research states plainly that “fat repositioning may be more appropriate for patients with significant tear trough deformities or excess skin,” while filler “may be better suited for patients with milder tear trough concerns.”

A properly trained practitioner should tell you honestly if filler is not going to solve your actual concern rather than injecting anyway. If your issue is genuinely bulging fat rather than a hollow, filler added on top can occasionally make the area look more crowded and puffy, not less. And if your concern is pigmentation rather than shadow, covered earlier in this guide, filler will simply not touch it, no matter how skilfully it is injected.

Filler versus the alternatives

Filler is one option among several for under-eye concerns, and the right one depends entirely on what is actually causing your particular problem.

Topical treatments are worth a try first if pigmentation is your main concern, since they carry essentially no procedural risk. If your priority is lower-face contouring rather than the under-eye area, our chin filler guide and dermal fillers guide cover other facial areas in the same depth. Platelet-rich plasma, made from your own blood, has modest evidence for improving skin quality and colour evenness, but it is not a proven substitute for filler when genuine volume loss is the cause, since the two work through completely different mechanisms. Surgery remains the more durable, and more invasive, answer for people with genuine fat herniation or excess skin that filler cannot correct.

Who can legally give you tear trough filler in Australia

The same Schedule 4 prescription framework covered in our dermal fillers guide applies here. Only a registered medical practitioner, dentist or nurse practitioner can prescribe it, and a registered or enrolled nurse can administer it under that prescription. Given the vascular risk covered earlier in this guide, genuine experience specifically with the tear trough matters more here than for almost any other filler area, and it is entirely reasonable to ask directly how many years an injector, including a registered nurse, has spent working on this specific zone.

Is tear trough filler right for you?

• Your under-eye darkness is genuinely a shadow or hollow, not primarily skin pigmentation, which a proper consultation should confirm rather than assume.
• You have mild to moderate hollowing rather than significant bulging fat pads or excess skin, which would need a surgical opinion instead.
• You understand and accept the genuine, if rare, vascular risk specific to this area, and are prioritising practitioner experience over price.
• You are comfortable with a temporary result, roughly 9 to 18 months, that will need repeat treatment to maintain.
• You are prepared for the possibility of temporary swelling or, less commonly, delayed puffiness appearing well after treatment, both of which are manageable if they occur.
• You are booking with an AHPRA-registered practitioner who has genuine, specific experience with this exact area, not just filler in general.

Questions worth asking before you book

1. Are you AHPRA-registered, and can I see your registration details?
2. What do you think is actually causing my under-eye darkness, shadow, pigmentation, or a combination?
3. Will you be using a cannula, and what injection plane do you use for this area specifically?
4. How many years of experience do you have specifically with tear trough filler, not filler generally?
5. What is your emergency protocol if you suspect a vascular complication, and do you keep hyaluronidase on hand?
6. Can I see before-and-after photos of your own previous tear trough patients?

Tear trough filler, done properly by a genuinely experienced practitioner, is one of the more effective treatments available for a specific, common concern, a shadow that no amount of sleep or concealer quite fixes. It also carries a real, serious risk that deserves to be taken seriously rather than glossed over. Choose your practitioner on genuine experience with this exact area and honest communication about whether filler will actually solve your specific concern, not on whoever offers the lowest price.
