What is Tear Trough Filler?

In this guide, we explain everything you need to know about tear trough fillers, including the benefits, risks, the treatment process and how they compare to surgical options.

Tear trough filler is a dermal filler treatment that addresses the indentation or hollow area under the eyes, called the tear trough. As time goes on, the fat and collagen that occurs naturally in this region decrease, causing dark circles and a hollow look. Injecting a hyaluronic acid-based filler into this area will restore volume, which reduces shadows and creates a smoother transition area between the lower eyelid and the cheek.

Hyaluronic acid is the most common type of filler used for this procedure because it holds moisture and integrates well with the skin. The treatment can be done rather quickly and is also minimally invasive and typically requires little to no downtime, making it a common choice for aesthetic patients looking to refresh their under-eye area but without surgery.

How Long Does Tear Trough Filler Last?

The longevity of tear trough filler varies based on the type of filler used, a person’s metabolism and lifestyle factors. Average results will last anywhere from 9 to 18 months. Since the area under the eyes has less movement than, say, the lips or cheeks, fillers there will typically break down at a slower rate.

Several factors may affect how long the results last:

Fillers – In this area, hyaluronic acid fillers such as Juvederm or Restylane generally last longer.
Metabolism – Those with a higher metabolism may be able to dissolve the filler at a faster rate.
Lifestyle factors – Smoking, excessive sun exposure, and poor skin care can accelerate the breakdown of the filler.
Injection technique – A skilled injector will position the filler in a manner that will maximise longevity and create a result with a natural appearance.

Though effects are not permanent, patients can maintain results with touch-up treatments as needed. Others notice longer-lasting results after multiple treatments since the filler can stimulate collagen over time.

Is Tear Trough Filler Safe?

Yes, tear trough filler is safe when carried out by a trained and experienced practitioner. The best-known example of temporary fillers, hyaluronic acid fillers are biocompatible, and can be dissolved with hyaluronidase if necessary. However, as any cosmetic procedure has risks associated with it.

Common side effects include:

Mild swelling and bruising — These tend to be temporary and dissipate in a few days.
Temporary lumpiness – While this is one of the most common side effects, it usually gets better on its own or with gentle massage.
Bleeding at the injection site – These symptoms will be temporary.

More serious risks, though rare, include:

Vascular occlusion – If the filler is injected into a blood vessel, it may block blood flow, resulting in complications.
If placed too superficially, it can create a bluish tint under the skin – referred to as the Tyndall effect.

To reduce risk, always seek a medically trained injector who performs under-eye treatments regularly.

Who is a Good Candidate for Tear Trough Filler?

Tear trough filler is ideal for patients who have:

Hollow or sunken under-eyes – This can also be due to ageing or genetics.
Mild to moderate dark circles – Due to volume loss instead of pigmentation.
Good skin elasticity – Loose or very thin skin may not hold the filler well.
Realistic expectations – While filler can improve the look of your under-eyes, it won’t take away all the signs of ageing.

Who may not be a good candidate?

Those with prominent under-eye bags – These are best treated with surgery.
People with thin, crepey skin — Filler can look more obvious or won’t settle in well.
People with chronic puffiness or swelling – Filler can increase fluid retention beneath the eyes.

Understanding the Tear Trough Area

The tear trough refers to the hollowed groove that travels from the inner corner of the eye down toward the cheek. This means fat loss, collagen depletion, and alterations in bone structure that come with age form it.

This is a delicate area because:

The skin is on the thin and sensitive side, it easily bruises.
There are many blood vessels, which increases the risk of swelling and complications.
Over time the orbital septum weakens, contributing to under-eye hollows and shadows.
Due to these complexities, treatment is best performed by a skilled practitioner who knows facial anatomy.

Tear Trough Filler Treatment Process

It usually takes 30 to 45 minutes to complete, and involves the following steps:

Consultation – The practitioner will analyse your under-eye area, ask about your goals, and decide whether filler would be a good fit.
Preparation – The skin is cleansed, and a numbing cream may be used for pain reduction.
Injection – The filler is precisely injected into the tear trough with a fine needle or cannula.
Massage – The therapist gently massages the area, providing a smooth integration.
Aftercare instructions – Patients should not touch the area too much, avoid hard work and alcohol for 24-48 hours.

What to Expect After Tear Trough Filler

Recovery from tear trough filler is generally straightforward, but knowing what to expect in the days afterwards can make the process feel much easier to plan around.

Swelling and bruising timeline

Swelling tends to peak around days two to three, so the area may look more pronounced than you expected at first. This is temporary. By days seven to ten, most patients find that swelling has settled considerably and the results begin to look as expected. Bruising, if it appears, usually follows a similar timeline and can be covered with concealer once the injection sites have closed.

Applying ice in the first 24 hours

Applying a clean cold compress or wrapped ice pack for short intervals during the first 24 hours can help reduce swelling. Do not apply ice directly to the skin, and avoid pressing firmly on the treated area.

Exercise and alcohol

Avoid strenuous exercise and alcohol for 48 hours after treatment. Both increase blood flow and can make swelling and bruising around the under-eye area more noticeable.

Returning to skincare and makeup

Avoid applying makeup and skincare products directly to the treated area for at least 24 hours. After that, you can return to your usual routine, although it is best to avoid rubbing or applying firm pressure around the eyes while any tenderness remains.

When to contact the clinic

If your symptoms appear to be getting worse after day three rather than improving, or if you notice unusual pain, skin discolouration, or any changes in your vision, contact the clinic promptly. These can be early signs of a complication that needs attention.

Side Effects and Potential Risks

Most side effects are mild, but it’s important to know possible risks. The most common side effect almost always is swelling and bruising, which generally go away in a couple of days. The less common side effects, such as lumpiness or asymmetry, can often be corrected by massaging gently or with more treatment.

In rare instances, more severe complications, including vascular occlusion or infection, may occur. This is why it is important to choose an experienced injector. An expert physician will know how to minimise the risks, how to detect complications early, and will know how to institute corrective action if necessary.

How Does Tear Trough Filler Compare to Surgical Treatments?

Tear trough filler is well suited to patients who want a non-surgical approach to under-eye hollowness. It works by restoring volume naturally and can deliver quick results with minimal recovery time, making it an appealing option for people who want a refreshed appearance without surgery. The trade-off is that results are not permanent and maintenance treatments are needed.

Lower blepharoplasty is the main surgical alternative. This procedure removes excess skin and fat from beneath the eyes and is better suited to patients with significant under-eye bags or sagging skin, both of which filler cannot adequately address. Recovery typically takes two to four weeks, but the results can be long-lasting.

One of the clearest advantages of filler over surgery is reversibility. Hyaluronic acid filler can be dissolved with hyaluronidase if a patient is unhappy with the outcome, whereas surgical changes are permanent. Filler also avoids the costs and risks associated with theatre and anaesthesia, although ongoing top-up treatments mean cumulative costs can increase over time.

The right choice depends on the individual’s concerns, anatomy and goals. Patients with mild to moderate hollowness may be good candidates for filler, while those with pronounced under-eye bags or loose skin are more likely to benefit from surgery.

The cost of tear trough filler in the UK varies primarily according to the amount of product required, which differs from patient to patient. Because of this, a consultation is the most reliable way to receive an accurate, personalised quote. For a general overview of what to expect to pay, find out more about tear trough filler costs.

Types of Fillers Used for Tear Troughs

Not all hyaluronic acid fillers behave in the same way, and the under-eye area requires a product with the right consistency and spreadability. The table below outlines the three fillers most commonly used for tear trough treatment.

Filler Name	Key Characteristic	Best Suited For
Restylane	Smooth, firm consistency that integrates naturally with surrounding tissue	Moderate to deep hollows with good skin elasticity
Juvederm Volbella	Softer formulation that delivers subtle, low-profile correction	Mild hollowness, first-time patients or those wanting a conservative result
Teosyal Redensity II	Hybrid formula developed specifically for the periorbital zone, with lower hydrophilicity than standard HA fillers	Patients prone to post-treatment swelling or those with thinner under-eye skin

Product selection depends on individual anatomy, though at Botonics, we generally favour Restylane for tear trough correction. In our experience it integrates smoothly with the delicate under-eye tissue, offers reliable longevity (typically 8–12 months, sometimes longer), and gives consistent, natural-looking results. Most patients need 2.0ml or more depending on the degree of hollowness.

Key Considerations Before Undergoing Tear Trough Treatment

Make sure to think about the following before opting for tear trough filler:

Pick an experienced injector — A skilled injector is safer and produces more natural results.
Understand the limitations – Filler works best for volume loss, not pigmentation or excess skin.
Watch out for risks – While relatively safe, there can be complications if done incorrectly.
Committing to upkeep — Fillers are temporary, and you need touch-ups over time.

Frequently Asked Questions

Does tear trough filler hurt?

A numbing cream is applied before treatment, so discomfort is minimal. Most patients describe a feeling of mild pressure during the injections rather than pain.

At what age should you consider tear trough filler?

Volume loss under the eyes can begin at different ages depending on genetics and lifestyle, and it may be worth discussing filler when it becomes a noticeable concern. There is no upper age limit, provided the skin is in suitable condition.

How much filler is typically needed?

The amount of filler required varies depending on the degree of hollowness, the product used, and your individual anatomy. Your practitioner will confirm the appropriate volume during your consultation.

What happens if I dislike the results?

Hyaluronic acid filler is reversible. If you are unhappy with the outcome, it can be dissolved at any time using an enzyme called hyaluronidase.

Conclusion

The under-eye area can be rejuvenated using the effective non-surgical treatment of tear trough filler to replenish lost volume and reduce shadows. It provides a minimally invasive way to get a refreshed, youthful look, with minimal downtime.

The treatment is typically safe, but finding a qualified practitioner is essential for best results. If you are interested in tear trough filler, book a consultation with a qualified provider here at Botonics to see if it’s the right option for you.
