Hyaluronic Acid Under-Eye Filler: Benefits, Risks and Results

Dark circles, hollow under-eyes and a tired appearance can develop for several reasons, including ageing, genetics, reduced skin elasticity and changes in facial volume. Hyaluronic acid under-eye filler is a non-surgical aesthetic treatment that may help improve the appearance of hollow areas beneath the eyes by restoring lost volume. 

However, it is not suitable for every type of dark circles. Understanding how the treatment works, its potential benefits, risks, and recovery can help you decide whether it is an appropriate option for your under-eye concerns.

What Is Hyaluronic Acid Under-Eye Filler?

Hyaluronic acid (HA) is a naturally occurring substance in the body that helps retain moisture and maintain tissue hydration. In aesthetic medicine, it is used in dermal fillers to restore volume and improve facial contours.

Under-eye filler, also known as tear trough filler, involves carefully placing a suitable hyaluronic acid-based gel beneath the lower eyelid to address selected cases of volume loss.

The tear trough is the groove between the lower eyelid and upper cheek. When this area becomes hollow, it can create shadows that make the eyes appear tired or accentuate dark circles.

Unlike topical eye creams, injectable fillers work beneath the skin to provide structural support and restore volume.

How Does Hyaluronic Acid Under-Eye Filler Work?

The treatment uses a carefully selected hyaluronic acid gel to improve the transition between the lower eyelid and cheek.

During treatment, a qualified practitioner assesses the under-eye anatomy and determines whether adding volume is appropriate.

The procedure generally involves:

1. Consultation: Your practitioner examines the under-eye area, discusses your concerns, and reviews your medical history.
2. Preparation: The treatment area is cleansed, and appropriate preparation is completed.
3. Filler placement: A suitable HA filler is carefully administered using an appropriate injection technique.
4. Post-treatment guidance: You receive personalised aftercare instructions and information about potential reactions.

The aim is to soften the appearance of hollows and shadows while maintaining natural facial proportions.

What Are the Benefits of Tear Trough Filler Treatment?

For carefully selected patients, under-eye dermal fillers may offer several aesthetic benefits.

1. Improves Under-Eye Hollowness

Volume loss beneath the eyes can create a noticeable depression between the lower eyelid and cheek. HA filler can restore some of this lost volume, making the transition appear smoother.

2. Reduces Shadows That Contribute to Dark Circles

Not all dark circles are caused by pigmentation. Some result from shadows created by hollowing beneath the eyes.

By addressing the underlying depression, filler may reduce this shadowing and create a more refreshed appearance.

3. Creates a Smoother Under-Eye Contour

In suitable cases, restoring volume can improve the contour between the lower eyelid and cheek. This may help reduce the appearance of tired-looking eyes without changing your natural facial features dramatically.

4. Provides Temporary, Reversible Volume Correction

Most hyaluronic acid fillers can be dissolved using an enzyme called hyaluronidase when clinically appropriate. However, reversal is not always straightforward, and dissolving filler carries its own risks.

The treatment is temporary, so results gradually change as the body breaks down the filler.

Who Is a Suitable Candidate for Under-Eye Filler?

Hyaluronic acid injections may be considered for adults with visible tear trough hollows that contribute to a tired appearance.

You may be suitable if:

• You have noticeable hollowness beneath your eyes.
• Volume loss creates shadows between your lower eyelids and cheeks.
• Your skin and under-eye anatomy are appropriate for filler placement.
• You have realistic expectations about the results.
• You do not have medical or anatomical factors that make treatment unsuitable.

However, filler is not necessarily the right solution for everyone.

People with prominent under-eye bags, significant puffiness, excess skin or certain anatomical characteristics may experience unsatisfactory results from additional volume.

Dark circles caused primarily by pigmentation or visible blood vessels also require a different approach.

A face-to-face assessment is essential before recommending treatment.

What Are the Risks and Side Effects of Under-Eye Filler?

The under-eye area has delicate skin and complex anatomy, making tear trough treatment particularly demanding.

Common temporary side effects include:

• Swelling around the injection site.
• Bruising or redness.
• Tenderness and mild discomfort.
• Temporary unevenness or lumpiness.
• Increased puffiness in the treated area.

Other complications can include prolonged swelling, filler migration, visible blue-grey discolouration (the Tyndall effect), infection, and contour irregularities.

Rare but serious complications: Accidental injection into a blood vessel can restrict blood supply and cause tissue damage. Facial filler injections have also been associated with visual disturbances, including blindness.

The US Food and Drug Administration explains these potential complications in its official dermal filler safety guidance.

This is why appropriate anatomical knowledge, practitioner training, careful patient selection, and an emergency complication-management plan are essential.

How Long Do Hyaluronic Acid Under-Eye Fillers Last?

The longevity of under-eye filler varies depending on several factors, including:

• The specific filler formulation.
• The amount of product used.
• Individual metabolism.
• Under-eye anatomy and tissue characteristics.
• Previous filler treatments.

Results may last several months or longer, but there is no guaranteed duration for every patient.

A 2024 randomised controlled clinical study involving 333 participants investigated HA filler for moderate-to-severe under-eye hollows. Researchers reported an 87.4% treatment response at three months. 

Among treated participants, 63.5% maintained the defined improvement through month 12 after the initial treatment. These findings relate to the specific filler and treatment protocol studied, not every under-eye filler product.

What Is the Recovery Like After Under-Eye Filler?

Recovery is generally manageable, although temporary swelling and bruising are possible.

Your practitioner should provide individual aftercare instructions. These may include:

• Avoid rubbing or applying pressure to the treated area.
• Follow advice about exercise and strenuous activity.
• Avoid excessive heat if advised during the initial recovery period.
• Keep the treatment area clean.
• Attend any recommended follow-up appointment.

Mild swelling or bruising may settle over several days, but some reactions can last longer. Contact your practitioner if symptoms are worsening or unusual.

Seek urgent medical attention if you experience severe or increasing pain, skin colour changes, sudden visual disturbances, or any sudden loss of vision after filler treatment.

Is Under-Eye Filler Better Than Lumi Eyes?

The two treatments address different under-eye concerns.

At Sarivaa Aesthetics, the distinction is important when choosing an appropriate treatment.

Lumi Eyes uses polynucleotide technology to focus on under-eye skin quality, whereas tear trough filler restores volume in selected cases.

Neither treatment is suitable for everyone. Read our guide to Lumi Eyes vs Tear Trough Filler: Which Treatment Is Right for Your Under-Eyes? for a more detailed comparison.
