1 Under-eye filler explained: how the treatment works

Under-eye filler works by placing a soft, lightweight hyaluronic acid gel, typically Lumiera, into the tear trough to support the under-eye structure and smooth the transition between the lower eyelid and the cheek. By restoring this underlying framework, the filler reduces the depth of the groove, improves light distribution and diminishes the appearance of dark circles. The gel integrates naturally with the tissue, maintaining a natural look and expression. A full session takes 20–30 minutes, and most fillers used in this delicate area contain lidocaine for enhanced comfort.

2 Ideal candidate for under-eye filler: key factors to consider

You may be a suitable candidate if you:

  • Have prominent dark circles caused by volume loss or tear trough hollowing.

  • Notice a tired appearance despite adequate sleep.

  • Want to soften shadows without surgery.

  • Have realistic expectations and stable skin quality in the lower eyelid area.

A professional assessment determines whether filler, skincare, PRP or a combined approach is most appropriate.

3 Under-eye filler session: step-by-step

Under-eye filler follows a precise protocol to ensure safety and natural-looking results:

Consultation and evaluation:

Assessment of tear trough depth, skin thickness and contributing factors.

Preparation:

Cleansing, disinfection and optional numbing cream for comfort.

Injection phase:

Lumiera filler containing lidocaine is placed with a fine needle or micro-cannula to restore volume and soften shadows.

Refinement:

The injector adjusts placement to ensure symmetry and smooth blending with the mid-face.

Post-treatment guidance:

Instructions are given to minimise swelling and support proper integration.

4 Under-eye filler before and after: recovery timeline

Recovery is generally quick, with results refining over the first two weeks.

Immediately after:

Mild swelling and slight redness; the area already appears brighter.

Days 1–3:

Swelling decreases and the contour becomes smoother.

Days 4–7:

The filler integrates naturally with the tissue.

Week 2:

Final results appear with a rested and more uniform look.

Results typically last 9–12 months, depending on filler properties, metabolism and lifestyle.

5 Recovery tips after under-eye filler for smooth healing

These steps support optimal healing and long-lasting results:

  • Avoid touching or massaging the area for the first 24 hours.

  • Sleep slightly elevated the first night.

  • Avoid intense exercise, heat and steam rooms for 24–48 hours.

  • Use SPF daily to protect skin quality.

  • Stay hydrated to support tissue integration.

6 Potential risks of under-eye filler to be aware of

Under-eye filler is usually safe when performed by experienced injectors, but mild reactions may occur.

  • Common effects: Mild swelling, redness or tenderness immediately after treatment.

  • Specific risks: Temporary asymmetry or slight lumpiness as the filler settles.

  • Rare risks: Vascular complications (very rare), migration (uncommon but possible), or infection (rare, especially without proper hygiene).

Choosing a qualified practitioner significantly reduces these risks.

KEIT Day Hospital has clinical facilities dedicated to aesthetic medicine treatments, organised to ensure appropriate standards of hygiene, procedural precision and patient comfort.
For under-eye filler treatment, the doctor assesses the depth of the tear trough, skin thickness and volume distribution in the periocular region, using instruments and materials specifically designed for injectable procedures. Treatment is performed using fine needles or sterile, single-use microcannulas, selected according to the patient's anatomical characteristics and the injection technique.
The organisation of the clinical facilities and the availability of medical resources allow the different stages of the procedure to be managed, from skin preparation to observation immediately after treatment.

KEIT Day Hospital works with medical professionals experienced in aesthetic medicine, injection techniques and facial anatomy. For under-eye filler treatment, knowledge of the anatomical structures around the eyes is essential for identifying the injection planes, considering the course of blood vessels and determining the quantity and distribution of the product.
Treatment is personalised according to the depth of the tear trough, skin quality and the presence of any under-eye bags or swelling, avoiding excessive correction that could make the filler visible or accentuate irregularities.
An additional advantage is the presence of a multidisciplinary medical team within KEIT Day Hospital, allowing specialists in anaesthesia and intensive care or other medical disciplines to be involved when additional assessments or specific medical assistance are required.

Before under-eye filler treatment, the doctor carries out an individual assessment of the periocular anatomy, tear trough depth, skin condition and the patient's expectations. The consultation includes taking a medical history, with particular attention to allergies, medications being taken, previous aesthetic treatments, skin infections and possible contraindications.
Assessment of the under-eye region makes it possible to distinguish shadows caused by volume loss from dark circles primarily caused by pigmentation, skin translucency or vascular congestion. Treatment is not planned according to standard filler quantities but according to the anatomical characteristics and the degree of correction actually required.
When filler is not the most appropriate solution, for example in the presence of prominent under-eye bags or a marked tendency towards swelling, the doctor assesses the available alternatives and discusses their limitations with the patient.

KEIT Day Hospital follows hygiene and infection prevention protocols that include disinfecting clinical areas, skin antisepsis and the use of sterile, single-use devices during injectable treatments. For under-eye filler treatment, particular attention is paid to proper skin preparation, the handling of needles and microcannulas and checking the packaging of the products used.
Each filler is identified by its brand name, batch number and traceability information, which are recorded in the patient's clinical documentation. The choice of hyaluronic acid takes into account the product's characteristics, the delicate nature of the periocular region, the injection plane and the desired result. These checks contribute to treatment safety and traceability.

Under-eye filler treatment is a minimally invasive procedure, generally performed without general anaesthesia. To improve patient comfort, products containing lidocaine or other local anaesthetic measures may be used when indicated. The proximity to the eyes and the complexity of the vascular anatomy require particular care when planning and performing injections.
In addition to temporary effects such as swelling or bruising, irregularities, persistent oedema or rare but serious complications, including vascular occlusion and, in exceptional cases, permanent visual impairment, may occur. Prompt recognition of symptoms and activation of emergency protocols are essential.
Managing suspected vascular occlusion caused by hyaluronic acid requires specific protocols, which may include the prompt use of hyaluronidase when indicated. Any visual disturbances require immediate emergency specialist care.
One of KEIT Day Hospital's distinguishing features is the availability of hospital infrastructure and a multidisciplinary medical team. The facility has three equipped operating theatres, specialists in anaesthesia and intensive care, equipment for monitoring vital signs, emergency management devices and a postoperative recovery room. These resources provide additional medical support, alongside the specific protocols required to manage complications associated with injectable treatments.

At KEIT Day Hospital, patient care continues after under-eye filler treatment has been completed. Patients receive personalised instructions on precautions to take, temporary effects that may occur and warning signs requiring immediate medical assessment.
Follow-up is determined according to the patient's individual response to treatment. A follow-up appointment after approximately 10–14 days, when indicated, allows the result to be assessed after the initial swelling has subsided, checking symmetry, the transition between the lower eyelid and cheek, and the possible presence of oedema or irregularities.
For international patients, care may also continue remotely through communication with medical staff and guidance on necessary follow-up appointments. KEIT Day Hospital also provides an emergency contact number, available 24 hours a day, 7 days a week.
