Tear Trough Filler: What It Actually Does for Under-Eye Hollows

Tear trough filler is a hyaluronic acid gel injected into the hollow between your lower eyelid and cheek, softening the shadow that can make you look tired even after a full night’s sleep. It is a walk-in appointment, usually 30 to 45 minutes, with minimal downtime, and results typically last 10 to 12 months, sometimes longer with the right product. It will not remove dark pigmentation, loose skin, or fat pads, those need different treatments or, in some cases, surgery. Done well, by an experienced injector using the right technique and product, tear trough filler is one of the most requested treatments at SIX1, because the result should read as well rested rather than obviously done. Below is what actually happens during treatment, how long it lasts, the real risks, and how it compares with the alternatives.

What is tear trough filler and how does it work?

The tear trough is the groove that runs from the inner corner of your eye toward your cheek. As we age, or simply due to genetics, this area can hollow out as fat pads shift position and the bone beneath thins slightly, casting a shadow that reads as tiredness or age regardless of how much sleep you get. Tear trough filler uses a soft hyaluronic acid gel, injected with a fine needle or blunt cannula, to fill that groove from beneath and blend the transition between eyelid and cheek. Hyaluronic acid is a sugar molecule your body already produces naturally in skin and connective tissue, which is part of why these fillers are considered reversible: if you are not happy with the result, it can be dissolved with an enzyme.

Am I a good candidate for tear trough filler?

Good candidates usually have a visible hollow or shadow caused by volume loss, rather than puffiness from fat pads, excess skin, or heavy pigmentation. If your main concern is loose or crepey skin rather than a hollow, filler alone will not solve it, and an honest practitioner should tell you that rather than injecting anyway. People with naturally very thin under-eye skin need a skilled hand and the right product, because this is one of the areas most prone to visible complications when technique or product choice is off. A proper face to face consultation, not a quick look at a photo, is the only reliable way to know which category you fall into and whether filler, a skin quality treatment, or a combination is the better route.

What happens during treatment?

After a numbing cream and a short consultation to map your anatomy, the practitioner injects small amounts of filler along the tear trough, often using a blunt cannula rather than a sharp needle to reduce the risk of bruising and vessel injury. Most appointments take 30 to 45 minutes from start to finish. You can expect some swelling and possibly mild bruising for a few days afterwards, and the final result settles in over roughly 2 weeks as any swelling resolves. Ice, avoiding strenuous exercise for 24 to 48 hours, and following your practitioner’s specific aftercare advice all help recovery along.

How long does tear trough filler last?

Clinical follow-up studies put the average duration at around 10 to 12 months, with some patients maintaining visible improvement at 18 months when a higher G-prime, meaning firmer, filler is used. Your own result depends on the specific product chosen, how quickly your body metabolises hyaluronic acid, and lifestyle factors such as sun exposure and hydration. Because the treatment is dose-dependent and builds gradually, most people choose to top up once a year rather than letting it fully wear off first.

What are the risks and side effects?

The tear trough is thin-skinned and sits close to a network of small blood vessels, so it carries more risk than filler placed in the cheek or lips, and it should only be performed by a practitioner with specific experience in this area. The most common issue is the Tyndall effect, a blue-grey tint that appears when filler is placed too superficially, because blue light scatters differently when it passes through very thin skin. Persistent puffiness, sometimes called malar oedema, can also develop if product sits in an area with poor lymphatic drainage. Rarer but more serious is vascular occlusion, where filler is accidentally injected into a blood vessel; this is uncommon but is exactly why cannula technique, product choice, and practitioner experience matter more here than almost anywhere else on the face. It is entirely reasonable to ask your practitioner directly about their specific tear trough experience and what they would do if a complication occurred.

Tear trough filler vs the alternatives

Filler is not the only option for under-eye hollows, and it is not always the right one. Here is how it compares with the other routes people typically consider:

Option	Best for	Downtime	Typically lasts
Tear trough filler	Visible hollowing from volume loss	1 to 3 days of possible swelling or bruising	10 to 12 months, up to 18
Skin boosters / Profhilo	Crepey texture and dehydration, not hollowing	Minimal	3 to 6 months
Sculptra (whole face volume)	Broader facial volume loss, not just the eye area	Minimal, builds gradually over months	Up to 2 years
Lower eyelid surgery	Excess skin or prominent fat pads	1 to 2 weeks	Long-term or permanent
Skincare and sleep	Mild dullness or dehydration lines	None	Ongoing, modest effect

If your main concern under the eyes is texture and dehydration rather than a true hollow, it is worth having your practitioner check whether a skin quality treatment would serve you better, alone or alongside filler.

Under-eye hollowing rarely happens in isolation. It is often one visible sign of the broader volume loss that changes the whole face after 40, alongside flatter cheeks and softer jawlines. If that sounds familiar, treating the tear trough alone may only address part of the picture.

FAQs

Does tear trough filler make you look years younger?

It softens the shadow that reads as tiredness, so people often say you look rested rather than obviously younger. It will not change bone structure, skin laxity, or pigmentation.

Can tear trough filler go wrong?

Yes, which is why practitioner experience specifically in this area matters more than for most other filler sites. The main risks are the Tyndall effect, persistent puffiness, and rarely, vascular occlusion. A thorough consultation and conservative first treatment reduce the risk.

How much filler do I need under my eyes?

This depends entirely on your anatomy and the depth of the hollow. Most practitioners start conservatively and review after a couple of weeks, since it is far easier to add more filler than to remove an overfilled result quickly.

Is tear trough filler painful?

Numbing cream is applied beforehand, so most people describe pressure and mild discomfort rather than significant pain. A blunt cannula technique tends to be more comfortable than a needle.
