Is Tear Trough Filler Safe? Risks, Side Effects & Expert Advice

Many people seek a fresher, more rested appearance, and tear trough filler has become a popular solution for under-eye hollows and dark circles. With its growing popularity, it’s natural to ask: “Is tear trough filler safe?”

When performed by an experienced medical professional using the right technique and high-quality products, tear trough filler is generally safe. However, understanding the potential risks, side effects, and patient suitability is essential before undergoing treatment.

This guide covers everything you need to know about tear trough filler safety, including what the procedure involves, possible complications, and how expert clinics minimise risk.

Tear trough filler is a non-surgical treatment designed to restore volume beneath the eyes, soften shadows, and improve the contour between the lower eyelid and cheek. It typically uses hyaluronic acid (HA) fillers, which are biocompatible and reversible.

The procedure is performed under local anaesthetic or numbing cream, requires minimal downtime, and produces subtle, natural results. Outcomes usually last between nine and twelve months, depending on the patient and product used. Unlike surgical procedures, tear trough filler is temporary and reversible, allowing adjustments over time.

The under-eye region is one of the most anatomically sensitive areas of the face, which is why tear trough filler carries a higher degree of risk compared to other facial treatments.

The skin here is extremely thin, sometimes less than 0.5mm, and lies directly over a network of delicate blood vessels, lymphatic channels, and the orbital septum.

Beneath the skin, the tear trough groove often contains minimal subcutaneous fat, meaning there is little cushion to protect the vessels. Injecting filler too superficially can lead to visible bluish discolouration, known as the Tyndall effect, while injecting too deeply or into a blood vessel can obstruct blood flow, potentially causing tissue damage.

The area’s lymphatic system is also highly sensitive, which means improper placement can result in prolonged swelling or puffiness. Moreover, the under-eye region is closely connected to the eye itself, so even though serious complications like visual loss are extremely rare, they are taken seriously in medically led clinics.

Because of this complex anatomy, precise technique, low-volume injections, and careful patient assessment are essential. Only clinicians with advanced knowledge of facial anatomy should perform tear trough filler to ensure both safety and natural aesthetic results.

Most side effects from tear trough filler are minor and temporary, a natural consequence of the delicate under-eye skin. Patients may experience bruising, swelling, or tenderness, usually resolving within a week. Minor lumps or unevenness can occasionally occur but often settle naturally or can be corrected with hyaluronidase.

Serious complications are rare but should be understood before treatment. These include:

• Vascular occlusion, where a blood vessel becomes blocked, potentially reducing blood supply to the skin
• Overfilling, resulting in puffiness or unnatural contours
• Persistent lumps or nodules, which may require enzymatic correction

Experienced practitioners minimise these risks with conservative, low-volume injections, precise placement along safe anatomical planes, and careful monitoring. Patients are also evaluated for pre-existing conditions such as very thin skin, previous surgery, or orbital fat protrusion, which may influence both safety and results.

Hyaluronic acid (HA) fillers are the safest option for the tear trough due to their biocompatibility, reversibility, and temporary effects. HA fillers allow clinicians to make small adjustments over time, producing subtle and natural rejuvenation.

If any complications arise, hyaluronidase can safely dissolve the filler, restoring the under-eye area to its pre-treatment state. Permanent fillers or unregulated products are strongly discouraged due to the difficulty of correcting complications and increased risk of lasting deformity.

Tear trough filler is best suited for patients with under-eye hollows, mild dark circles, and good skin elasticity who are seeking subtle rejuvenation rather than dramatic changes.

Patients with very thin skin, significant lower eyelid fat, or certain medical conditions may be better served by surgical interventions, such as lower eyelid blepharoplasty, which can address structural issues more effectively.

A thorough consultation is essential to assess facial anatomy, discuss expectations, and decide whether filler or surgery offers the safest and most appropriate results.

When performed by a trained medical professional, tear trough filler is far safer than many expect. Most complications occur when treatments are carried out by non-medical injectors, with insufficient anatomical knowledge, inappropriate products, or overly aggressive techniques.

At Dr Hass Clinic, we prioritise safety through conservative, low-volume injections, precise placement along safe anatomical planes, and continuous monitoring. Hyaluronidase is always available to reverse filler immediately if necessary, ensuring any issues can be addressed safely.

Side effects are generally mild and temporary, including bruising, swelling, or minor tenderness, while serious complications are rare under expert care. Tear trough filler is temporary, reversible, and minimally invasive, offering subtle under-eye rejuvenation with minimal downtime.

A thorough consultation is essential to assess suitability, discuss expectations, and plan the safest approach. With careful technique and experienced hands, tear trough filler can restore volume, smooth shadows, and refresh your under-eye area naturally and safely.
