Not all dark circles are treated the same way, and before filling we assess whether yours are caused by a hollow, by pigmentation or by the eye bag itself. Hyaluronic acid filler corrects the hollow, but in other cases the solution is different.

Tear trough filler is a non-surgical aesthetic medicine treatment that uses hyaluronic acid to improve hollowness, discoloration and skin quality in the under-eye area, adding radiance and a more rested appearance while always respecting facial harmony.
The aim is not to change your facial expression, but to rejuvenate the eye area, soften a tired appearance and improve the transition between the eyelid and the cheek, for a natural, balanced result suited to each patient.
This is a volume problem: the groove under the eye becomes noticeable because support is lacking, and the shadow is cast by the hollow itself. It is the only type of dark circle that hyaluronic acid filler corrects directly, and the one that responds best.
Sometimes the groove shows because it is the cheekbone that has lost support. In those cases we consider treating the cheekbone first: filling the under-eye area alone does not resolve the shadow.
The eyelid skin has more melanin and looks brown, not hollow. This is common in darker skin tones and tends to run in families. Filler does not improve it, because the problem is color, not volume.
Here the approach is different: depigmenting treatments, peels specific to the area or pulsed light depending on the case, and consistent sun protection.
They look bluish or purplish because the blood vessels show through very thin skin. They get worse with tiredness, lack of sleep and fluid retention.
Filler can make them worse if it is placed superficially, because the product becomes visible with a grayish tone. That is why the prior consultation measures skin thickness before injecting, and in these cases the plan is usually a different one.
What you see is not a shadow but a bulge: the fat of the lower eyelid herniates and forms the bag. Filler does not correct it and can accentuate the step.
When the bag is the main cause, the indication is surgical, with a lower blepharoplasty. In consultation we tell one from the other before proposing anything.
Tear trough filler treatment has a guide price from €400, which may vary depending on each patient's individual needs.
As this is a fully personalized aesthetic medicine procedure, the final cost may be adjusted according to various clinical and aesthetic factors, such as the type of dark circle, the degree of hollowness, skin quality, the amount of product needed, the technique used and whether there have been previous treatments in the area.
Each treatment plan is designed after an individual medical consultation, in which the specialist determines the most suitable regimen to achieve a natural, safe improvement of the eye area.
The aim is to offer a clear, transparent quote tailored to each patient, focused on softening hollowness, improving a tired appearance and adding radiance to the under-eye area in a gradual, balanced and medically supervised way.

Tear trough filler is an aesthetic medicine treatment indicated to correct hollowness and shadowing under the eyes by injecting hyaluronic acid into the tear trough. It works by restoring volume to the area gradually and naturally, with results visible from the first session and no need for surgery.

Before the treatment, you have a consultation with the specialist doctor who will perform it, in which your face, skin quality and aesthetic goals are assessed to design a fully personalized plan. This consultation costs €50, deductible from your first treatment.

When the doctor considers it necessary, a NESAI Derm ultrasound is performed in Barcelona to assess the skin before treating: dermis thickness, density, collagen, fibers and sun damage.

Preparation is simple and requires no special care: the skin should be clean, with no makeup or creams, on the day of the session. You can come to your appointment as you normally would.

The treatment is performed in the doctor's office following the previously designed plan. The technique is adapted to the anatomy and the actual characteristics of each patient's periocular area, aiming to correct hollowness, soften the shadow and improve skin quality gradually and naturally, without altering your expression.

A treatment designed to enhance your natural beauty and help you look better, always respecting your identity and your expression.
The technique is not chosen by preference, but by what the examination shows: the thickness of the eyelid skin, the depth of the tear trough and whether there is product from previous treatments. The prior ultrasound lets us see this before injecting.
It is performed with a blunt cannula, which allows a more even distribution of the hyaluronic acid and reduces the risk of bruising and swelling. It is one of the most widely used techniques because of its safety and natural-looking results.
This consists of targeted injections with a fine needle in very specific areas. It allows greater precision in selected cases, although it may be associated with more swelling or small bruises.
The product is placed in a deep plane, on the bone, to restore structural support and improve hollowness without altering the skin surface, achieving a more stable, natural result.


Tear trough filler is indicated for people who want to improve hollowness, discoloration and a tired appearance in the under-eye area, whether due to genetic predisposition or to the changes that come with the passage of time, naturally and without surgery.
It is a treatment designed to rejuvenate the eye area, add radiance and soften the transition between the lower eyelid and the cheek, always preserving the natural expression of the face.
It is especially recommended if:
Indicated when there is volume loss in the area, helping to soften the groove and improve a tired-looking eye area.
Ideal for people whose eyes look dull or fatigued, even when they are getting enough rest.
Recommended in cases where dark circles have been present from an early age and do not improve with topical treatments.
Suitable when the passage of time causes thinning of the skin and greater hollowness in the periocular area.
To soften the step between the lower eyelid and the cheek, for a more even, harmonious eye area.
Designed for those who want to improve the under-eye area with a non-surgical, safe procedure with natural results.
Patient safety comes before any aesthetic result. Dark circle treatment should not be performed, or should be postponed, in the following cases:
| Contraindication | Reason |
|---|---|
| Pregnancy and breastfeeding | Injectable treatments are not performed during pregnancy or breastfeeding. |
| Active infection or lesion in the area | Herpes, folliculitis, dermatitis or open wounds: treatment is postponed until they have resolved. |
| Autoimmune disease or immunosuppression in an active phase | Requires individual assessment and, in some cases, a report from the specialist managing the case. |
| Anticoagulant treatment or a clotting disorder | Increases the risk of bruising; it is assessed with the prescribing doctor. |
| Known allergy to any of the components | Contraindicates the treatment. |
| Eye bags caused by significant fat herniation | Filler does not correct them and can worsen their appearance; the indication would be surgical. |
| Tendency to fluid retention | The periocular area is especially sensitive and may swell more. |
Dark circle treatment is safe when performed by a licensed physician in an authorized center using approved medical devices. Even so, every medical procedure has a profile of possible effects that it is only honest to share with you.
Instituto de Benito is a benchmark in aesthetic medicine treatments.
The team tailors each treatment to the patient, with the aim of a natural result.

«I always explain to my patients that this is a delicate treatment»

At Instituto de Benito, patient safety is always the top priority. All aesthetic medicine treatments are performed after a thorough medical consultation and with personalized follow-up, which makes it possible to anticipate and manage any possible effect or issue early, ensuring a safe, responsible approach.

A more rested, radiant and rejuvenated eye area, with a visible improvement in hollowness and a tired appearance. The result is natural and harmonious, noticeable immediately, and settles gradually over the first few weeks.
Tear trough filler starts at €400 at Instituto de Benito.
The final cost depends on the amount of product needed, on whether cheekbone support needs to be treated first and on whether there are previous fillers in the area that need to be assessed. The prior ultrasound lets us see this before injecting.
Discomfort is usually mild. You may feel slight pressure or a pricking sensation, which most patients tolerate well. If necessary, topical anesthesia is applied for greater comfort.
It usually lasts 12 to 18 months, depending on the patient's metabolism, the type of hyaluronic acid used and the characteristics of the treated area.
Tear trough filler is a safe procedure when performed by specialized doctors using products suited to the periocular area. Even so, like any aesthetic medicine treatment, it can have side effects.
At Instituto de Benito, safety is the priority and the treatment is performed under strict medical protocols, minimizing risks and ensuring a precise, controlled approach.
We recommend avoiding makeup for the first 24 hours to reduce the risk of infection and allow the product to integrate properly.
Most patients resume their usual routine the same day or the next day. We advise avoiding intense exercise, heat and saunas for 24–48 hours.
No. When the treatment is properly indicated and performed, the result cannot be felt to the touch and looks completely natural.
Yes. It can be combined with treatments such as skin boosters, laser or radiofrequency, always after a personalized medical consultation.
