Tear trough filler has a reputation for two opposite things: producing some of the most striking under-eye improvements, and producing some of the most visible filler complications anywhere on the face. Both reputations are deserved. The difference between the two is almost always patient selection and technique, not product.
I am Shontelle, the registered nurse at Silk Clinical Aesthetics. This article walks through what tear trough filler can do, who it is right for, and the specific anatomical and clinical reasons it sometimes makes things worse rather than better.
What the Tear Trough Actually Is
The tear trough is the natural depression that runs from the inner corner of the eye, along the lower orbital rim, towards the cheek. In a young, well-supported face, this depression is shallow and barely visible. With age, fat loss in the upper midface, and bony changes in the orbit, the depression deepens and becomes a visible groove. The skin overlying the area is some of the thinnest on the body, which is why even small shadows or volume changes are noticeable.
Tear trough filler aims to add a small volume of hyaluronic acid filler beneath the skin, in a deep plane against the bone, to soften the depth of the depression and reduce the shadow it casts.
That is the whole goal. Under-eye filler does not lighten dark pigmentation, it does not remove fat bags or "puffiness", and it does not work for hollowing caused by skin laxity rather than volume loss.
Who is a Good Candidate
Tear trough filler works well when the cause of the under-eye concern is a true volume deficit in the tear trough, with otherwise good skin quality, minimal puffiness, and adequate cheek and midface support.
The features that predict a good outcome:
- A clearly defined depression along the orbital rim.
- The tear trough shadow improves visibly when you push the cheek tissue gently upward.
- Skin under the eye is thin but elastic, not loose or crepey.
- Minimal protrusion of the lower lid fat pads (the "bags").
- The cheeks and midface have reasonable volume support.
- The patient does not have significant fluid retention or chronic under-eye puffiness on waking.
When all of these align, a small amount of carefully placed filler can produce a striking, natural improvement. The eye looks rested, the shadow softens, and the area looks like it did several years earlier without looking obviously treated.
Who is a Poor Candidate
The same treatment in the wrong patient produces persistent puffiness, a bluish tinge under the eye, visible bumps, or a heaviness that looks worse than the original concern. Several anatomical and lifestyle features are poor predictors.
Significant lower lid fat herniation (true under-eye bags). Filler placed below a protruding fat pad makes the bag sit on a platform of filler, which makes it more visible, not less. This is one of the most common reasons tear trough filler disappoints. The right answer in this scenario is often surgical lower blepharoplasty, not filler.
Loose, crepey, or sun-damaged under-eye skin. Thin lax skin draped over filler often shows the filler's outline as a faint blue or grey shadow. This is called the Tyndall effect. It is a function of how light scatters through hyaluronic acid sitting too close to the surface.
Dark pigmentation as the primary concern. Pigment under the eye is not improved by filler. Sometimes it looks slightly worse, because the volume change brings the discolouration into sharper light. Pigment is a separate conversation, often involving topical treatments and skin work.
Significant fluid retention or morning puffiness. Hyaluronic acid attracts water. In a patient who already has fluid retention in the under-eye area, filler can compound the puffiness rather than soften the hollow.
Inadequate midface support. When the cheeks have lost significant volume, treating the tear trough alone leaves the midface unsupported. The result often looks unbalanced. The right plan in this scenario usually starts with cheek filler, with tear trough done after, if at all.
Medical conditions that cause periorbital changes. Thyroid disease, kidney issues, allergies, and chronic sinus issues can all produce under-eye changes that look like tear trough hollowing but are not. Treating these with filler does not address the underlying cause.
When I see a patient who requests tear trough filler but falls into one of these categories, I will say so clearly. Sometimes the conversation moves to a different treatment. Sometimes it moves to a referral. Sometimes the right answer is to leave the area alone. We do not treat tear troughs in patients who are not good candidates, regardless of what they have asked for.
Why Tear Trough Filler Goes Wrong
Even in good candidates, tear trough filler is technically demanding. The plane of injection, the type of product, and the volume used all matter more here than almost anywhere else on the face.
Wrong product. Many hyaluronic acid fillers are too hydrophilic (water-attracting) for the tear trough. A filler that absorbs significant water in the body looks fine in the cheek but produces persistent puffiness in the under-eye. The right products for tear trough are firm, low-spread, low-hydrophilic gels.
Wrong plane. Filler placed too superficially shows through the skin, often as the bluish Tyndall effect. The correct plane is deep, against the bone, where the filler is supported and not visible from the surface.
Too much volume. The tear trough rarely needs more than 0.3 to 0.5 ml per side. Over-correction is harder to disguise in this area than anywhere else on the face. Less, reviewed at two weeks, then more if needed, is almost always the right approach.
Asymmetric correction. The two sides of the tear trough are rarely identical. Treating them as if they were produces visible asymmetry.
Filler migration over time. Even correctly placed tear trough filler can migrate or accumulate fluid over months or years. This is one reason the area should be reviewed regularly and excess filler dissolved early if it occurs.

What Good Treatment Looks Like
A considered tear trough treatment includes:
- A thorough assessment, in good light, with the patient sitting up. Lying back changes the appearance of the area and is not a useful position for assessment.
- A discussion of whether the tear trough is the right starting point or whether the cheek and midface should be addressed first.
- A small initial volume, usually 0.3 to 0.5 ml per side at most.
- Deep placement against the orbital rim, with cannula technique preferred over needle in most cases for safety and even distribution.
- A review at two weeks, with conservative top-up only if needed.
- Clear advice on when filler should be dissolved if the result is not what either of us wanted.
Tear trough filler is one of the few treatments where I will sometimes say the right answer is to dissolve previous work first, settle for a few weeks, and then reassess. Stacking new filler on top of old, partially migrated filler is a common cause of poor results.
What Tear Trough Filler Cannot Do
A short list of what to expect, and what not to expect:
- It can soften a true volume hollow.
- It cannot remove or reduce protruding fat pads.
- It cannot lighten pigmentation.
- It cannot tighten loose skin.
- It cannot fix issues caused by sleep, sinus, or systemic health concerns.
- It will not give you the under-eye area you had at 22.
If the issue is something tear trough filler does not address, no amount of correctly placed filler will fix it. The honest conversation is more useful than the treatment itself in those cases.
How Silk Approaches the Tear Trough
We treat the tear trough conservatively, in patients we have assessed as appropriate candidates, with products selected for low water-attraction and firm support. We use cannula technique in the deep plane against the orbital rim. We start small, review at two weeks, and add only if needed. We will dissolve filler that has migrated or accumulated rather than building on top of it.
We will say no to tear trough filler in patients who are not good candidates. This includes patients with significant fat herniation, very thin or lax skin, dark pigmentation as the dominant concern, or insufficient midface support. In those cases, we discuss alternatives or recommend leaving the area alone.

Frequently Asked Questions
How long does tear trough filler last?
Tear trough filler typically lasts 12 to 18 months in most patients, sometimes longer than other facial areas because the under-eye region is not heavily mobile. The longer duration is one reason careful product selection and placement matter; mistakes here can persist longer.
Can tear trough filler be reversed?
Yes. Hyaluronic acid filler can be dissolved with hyaluronidase, an enzyme injection. This works in the tear trough as it does anywhere else. We use it both to correct unwanted results and to reset an area before retreating.
Will tear trough filler get rid of dark circles?
Sometimes the appearance of dark circles is partly caused by the shadow of the tear trough hollow, in which case filler softens the appearance. If the darkness is true pigmentation, filler does not address it. The honest answer in your consultation will be based on what is actually causing the darkness in your specific case.
Can I have tear trough filler if I have under-eye bags?
Often, no. If the bags are caused by herniated lower lid fat, filler usually makes the appearance worse rather than better. The right answer is sometimes a surgical lower blepharoplasty referral. If the bags are caused by fluid retention or fatigue rather than fat, the picture is different. Assessment matters.
Should I have cheek filler before tear trough filler?
Often yes. The midface and cheek support the under-eye area structurally. Treating the tear trough in a patient with significant cheek volume loss can produce an unbalanced result. We assess the whole midface in your consultation and recommend the order accordingly.
Why do some people end up with persistent under-eye puffiness after filler?
Usually one of two reasons: the wrong product was used (too water-attracting), or the placement was too superficial. Both are correctable. Hyaluronidase dissolves the existing filler and the area resets. Choosing the right practitioner and discussing product selection up front prevents the problem from happening at all.
