Quick answer
Tear trough filler suits a true hollow: a groove running from the inner corner of the eye along the lower lid and cheek edge, where support has been lost. It does not suit a bag made of fat, a darkness made of pigment, or a festoon.
- Suits: a hollow that casts a shadow, in an eye whose lower lid skin is otherwise reasonably firm.
- Does not suit: bulging fat, pigment (brown or grey darkness), a festoon or malar mound, or fluid that comes and goes.
- Evidence: in a randomized trial, 83.1% of treated people improved by at least one grade at month 3 against 15.6% of controls.
- Risks: swelling and bruising are common; lumps and the bluish Tyndall effect are less so; a blocked blood vessel is rare and severe.
- Reversal: hyaluronic acid filler can be dissolved with hyaluronidase.
What is tear trough filler, and what does it treat?
Tear trough filler is hyaluronic acid gel placed under the skin of the groove between the lower eyelid and the cheek, to replace volume that has been lost. The groove is called the tear trough. When it deepens, light falls into it and the shadow reads as a dark circle or a tired eye, even though nothing is growing there.
Search terms overlap here: under eye filler, eye bag filler and tear trough filler usually mean the same treatment, but "eye bag" can describe four or five different problems. The article on which kind of eye bag you have separates them, and filler answers only one.
Who suits tear trough filler, and who does not?
Tear trough filler suits a hollow caused by lost support, and it is the wrong tool for most other under-eye problems. A published review of under-eye darkness lists heredity, excess pigment, pigment left after eczema or allergy, fluid, visible vessels, and shadowing from skin laxity and the tear trough. Only the last of those is a filler problem.
| Under-eye problem | What it is | Is filler the right tool? |
|---|---|---|
| Tear trough hollow | A groove from lost support, casting a shadow | Often considered, after examination |
| Fat bulge (puffy bag) | Fat pushing forward | No; filler adds volume and does not remove fat |
| Pigment | Brown or grey darkness in the skin | No; filler does not change colour in the skin |
| Festoon or malar mound | A fold of lower lid skin and fluid, below the bag | No; the reviews read treat these as separate problems |
| Fluid (morning puffiness) | Swelling that comes and goes | No |
| Thin, crepey skin | Loss of skin quality | Not on its own; filler does not address skin quality |
A systematic review of malar bags says their causes vary and that treatment must be individualised by extent and content, which is why the examination comes before the syringe. The fuller picture, including pigment, is in dark circles are not one problem.
Can filler fix puffy eye bags, dark circles or hollows after weight loss?
Filler can soften the shadow of a hollow, including a hollow that appears after fast weight loss, but it cannot remove a puffy bag or pigment. If the problem is a bulge, adding volume beside it does not remove the bulge, so a bulge needs a different plan.
Hollowing after rapid weight loss is a hollow problem in the first place. The article on hollow eyes after fast weight loss sets out why the groove forms and what the risks are. Energy devices are covered in can anything be done about eye bags.
What do trials report for tear trough and under eye filler?
In a randomized, single-blind trial of a hyaluronic acid filler (VYC-15L) for moderate or severe infraorbital hollowing, 83.1% of treated people improved by at least one grade at month 3, against 15.6% of controls. Three-dimensional imaging showed a mean volume gain of 0.733 mL on the left and 0.777 mL on the right at month 12. The study was supported by Allergan Aesthetics, the maker.
A meta-analysis of 31 reports and 2,556 participants found a pooled satisfaction rate of 91.0%. Two limits apply to both. They measure hollows, not bags or pigment, and satisfaction is what people say about the result, not a measurement of the result.
What are the risks of under eye filler?
The common effects are swelling and bruising, and the serious one is a blocked blood vessel. In the meta-analysis the pooled rates were swelling 19.2%, bruising 18.4%, redness 7.1% and a contour irregularity or lump 5.3%. The bluish discolouration called the Tyndall effect, where gel placed too shallowly shows through thin skin, was 0.9%.
In the randomized trial, most injection site responses were mild or moderate and settled within a week, but three people had swelling that began more than 30 days after treatment; two resolved within four days and one by 45 days. The tear trough appears on published lists of higher risk zones because of the vessels there, and the rare severe events, including vascular occlusion, are set out in the hollowing article and dermal filler risks. Anyone considering filler there should hear that part first.
How long does tear trough filler last?
In the randomized trial, imaging showed a volume gain still present at month 12, and the authors reported that the correction lasted through one year. That is one product in one trial. Duration varies with the gel, the person and the area, and the gel can stay in the tissue after it has stopped being visible.
The wider picture, including what makes filler fade faster, is in how long does filler last. Late lumps and swelling are covered in filler gone wrong.
Can tear trough filler be dissolved?
Yes. Hyaluronic acid filler can be dissolved with hyaluronidase, which is why it is the usual reversal. A review notes that controlled data are limited but clinical experience is large: the Tyndall effect and non-inflamed lumps are treated with low or moderate doses, while a blocked blood vessel needs immediate high-dose treatment.
In a retrospective review of 114 people at one clinic, the eyelid region received the most hyaluronidase injections (58), used for overcorrection, the Tyndall effect and late nodules, with no severe side effects reported in that protocol. Skin that turns white, grey or blue, unusual pain or any change in vision after filler is an emergency, not a reason to wait.
How do I choose where to have under eye filler in Malaysia?
Ask who will inject, how they will tell a hollow from a bag, what they will do if a vessel is affected, and whether hyaluronidase is on hand. Check that the product is registered; how to check the product explains the register.
The Retreat Clinic in Setia Alam lists tear troughs among the areas of facial contour its dermal fillers cover, and Dr Ong performs fillers himself, after examining which under-eye problem is present.
