What is Tear Trough Filler?

Tear trough filler is a hyaluronic acid injection used to reduce the hollow and shadowing beneath the eyes that makes you look tired. Results are subtle and natural-looking when done well, and typically last nine to eighteen months.

The under-eye area is one of the most common aesthetic concerns people bring to clinics. Dark circles, a hollow appearance, and that persistent tired look regardless of how much sleep you've had. Tear trough filler addresses the structural cause of this, but it's also one of the more technically demanding filler treatments. Here's what you need to know before considering it.

What is the tear trough?

The tear trough is the groove or hollow that runs from the inner corner of the eye diagonally down toward the cheek. It's a natural anatomical feature, but in some people it's more pronounced, creating a shadowed valley that reads as darkness or hollowness beneath the eye.

This hollow can be present from a relatively young age in some people, or it can deepen over time as facial fat pads shift and volume is lost in the mid-face. When the transition between the lower eyelid and the cheek is abrupt rather than smooth, the light hits it in a way that creates a shadow, which is what we perceive as a dark circle.

Not all dark circles are caused by the tear trough. Pigmentation, thin skin, visible blood vessels, and poor circulation all contribute too. Tear trough filler specifically addresses the hollow and shadowing caused by volume loss or a pronounced groove. It won't help dark circles caused purely by pigmentation.

How does tear trough filler work?

A small amount of soft hyaluronic acid (HA) filler is placed carefully beneath the eye, either in the tear trough itself or in the surrounding area, to smooth the transition between the lower eyelid and cheek. By filling the hollow, the sharp angle that causes shadowing is softened, and the eye area looks more rested and even.

The amount of filler used is small, usually 0.5 to 1ml across both eyes. The purpose is subtle correction, not volume addition. A well-executed tear trough treatment should be invisible, both in the sense that nobody should be able to see the filler and in the sense that the result should look like your natural face rather than a treated one.

Why is tear trough filler technically demanding?

The under-eye area is one of the most unforgiving places to inject filler for several reasons.

The skin here is the thinnest on the face. Any irregularity in placement, any excess product, or any lumpiness shows immediately. The Tyndall effect, where HA filler placed too superficially creates a bluish discolouration under thin skin, is a real risk in this area and one that requires careful depth control to avoid.

The anatomy is also complex, with blood vessels and lymphatic channels in close proximity. An injector who understands the anatomy of this specific area, not just general filler technique, is essential.

This is one of the treatments where the practitioner's experience matters most. A good result looks completely natural. A poor result can look worse than the original concern.

Who is tear trough filler for?

Tear trough filler is best suited to people with a hollow or pronounced groove beneath the eye that creates shadowing and a tired appearance. Good candidates typically:

Have a visible tear trough hollow rather than just dark pigmentation
Have reasonably firm skin in the under-eye area without significant laxity
Are looking for subtle correction rather than dramatic change
Have realistic expectations about what filler can and can't address

It's not suitable for everyone. People with very puffy under-eyes, significant skin laxity, or dark circles caused primarily by pigmentation may not benefit, and in some cases filler can make these concerns look worse. A thorough consultation with an experienced injector is important before proceeding.

Tear trough filler before and after: what to expect

Results from tear trough filler are typically visible immediately, though some swelling in the first 24 to 48 hours can temporarily affect the appearance. Once swelling settles, usually within a few days, the result reflects the final outcome.

What a good result looks like is a smoother, less hollow transition beneath the eye. The shadowing is reduced. The eye area looks more rested. The change is usually noticed by others as looking less tired, without being identifiable as treatment.

Results typically last nine to eighteen months, with variation depending on the individual's metabolism, the specific product used, and the area. The under-eye area tends to hold filler for longer than higher-movement areas like the lips.

Tear trough filler vs surgery

For people with significant skin laxity, fat prolapse (the bags rather than hollows under the eye), or concerns that extend beyond the tear trough, surgery may be a more appropriate option. Blepharoplasty (eyelid surgery) addresses structural issues that filler cannot correct and can produce more significant and longer-lasting results.

For those with a hollow tear trough and no significant laxity or bagging, filler is a meaningful and far less invasive alternative.

How much does tear trough filler cost?

Tear trough filler typically costs between £300 and £600 in the UK for both eyes. Prices vary by clinic and practitioner experience. This is a treatment where practitioner skill directly correlates with outcome, so selecting based on experience rather than price is worth doing.

Frequently asked questions

How long does tear trough filler last?

Tear trough filler typically lasts nine to eighteen months. The under-eye area tends to hold filler for longer than higher-movement areas of the face.

Does tear trough filler hurt?

A topical numbing cream is usually applied before treatment, and many practitioners also use a cannula (a blunt-tipped needle) rather than a sharp needle, which reduces discomfort and bruising risk. Most people find the treatment tolerable. Some mild tenderness for a day or two afterwards is normal.

What is tear trough filler?

Tear trough filler is a small injection of soft hyaluronic acid gel placed beneath the eye to fill the hollow that creates shadowing and a tired appearance. It smooths the transition between the lower eyelid and the cheek, reducing dark circles caused by hollowness rather than pigmentation.

How much does tear trough filler cost in the UK?

Expect to pay between £300 and £600 for both eyes at a reputable UK clinic. Practitioner experience is particularly important for this treatment given the delicacy of the area.

Can tear trough filler be dissolved?

Yes. Hyaluronic acid filler can be dissolved using an enzyme called hyaluronidase. This is an important safety net for this particular treatment, since any unsatisfactory result or complication can be reversed by an experienced practitioner.
