Nasolabial fold filler is a minimally invasive aesthetic medicine treatment that uses hyaluronic acid to soften the lines and folds that form between the nose and the corners of the mouth. This procedure helps restore lost volume, improve hydration and give the skin greater firmness, for a more rejuvenated, rested and natural-looking face.
Results are visible immediately, with a harmonious effect that respects facial expression. The treatment stimulates skin quality and can last between 8 and 12 months, depending on each patient's skin type and metabolism.


Nasolabial fold filler with hyaluronic acid is included in the guidelines of the Spanish Society of Aesthetic Medicine (SEME) on facial rejuvenation. The current technique prioritizes addressing the midface (cheek) as the primary cause of the descent, and only treats the fold directly when it is pronounced due to anatomy or is genetic in origin, not due to structural sagging.

The treatment is performed entirely in the doctor's office at Instituto de Benito in Barcelona or Madrid, in an outpatient session always designed and supervised by a licensed aesthetic doctor. It consists of the following steps:

Before the treatment, you have a consultation with the aesthetic doctor at Instituto de Benito, who studies your case, listens to your goals, rules out contraindications and designs a personalized plan. The first aesthetic medicine 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: the area must be clean and free of creams. The doctor will tell you whether you should avoid any medication (anticoagulants, NSAIDs) in the days beforehand to minimize bruising, and will discuss with you any circumstances relevant to your safety.

The doctor disinfects the area, applies topical anesthesia if necessary and performs the microinjections with very fine needles, following the plan designed. The session is carried out entirely in the doctor's office and the patient returns to their routine immediately.

Results appear within the timeframe expected for the treatment, with a natural, harmonious finish. The doctor gives you home care instructions and schedules your follow-up appointments.


The final price depends on the area or areas to be treated, the product or cocktail used and the number of sessions the doctor recommends after the consultation. The first aesthetic medicine consultation costs €50 (deductible from your first treatment). We offer financing for extended treatments and treatment packages.
Nasolabial fold filler is indicated for people in good general health who fit any of these profiles. Final suitability is confirmed by the doctor after a personalized consultation.
The descent of the midface deepens the fold over the years.
In people who have had pronounced folds since they were young.
When the folds convey tiredness or sadness.
Combined with cheek filler to correct the cause as well as the effect.
The lines from the corner of the mouth toward the chin are treated with the same technique and product.
As part of a complete harmonization plan.
Patient safety comes before any aesthetic result. Nasolabial fold filler should not be performed, or should be postponed, in the following cases:
| Contraindicación | Motivo |
|---|---|
| Pregnancy and breastfeeding | There are not enough safety studies on the fetus or the breastfed infant. |
| Clotting disorders or anticoagulants | High risk of extensive bruising or bleeding. |
| Active autoimmune diseases | Lupus, scleroderma, dermatomyositis: unpredictable tissue response. |
| Immunosuppression | Active cancer treatment, uncontrolled HIV, transplant recipients. |
| Known allergy to the product | Risk of anaphylaxis. |
| Tendency to keloids | Risk of scarring. |
| Under 18 years of age | Unless very specifically prescribed by a doctor. |
Nasolabial fold filler is a safe treatment when performed by a licensed doctor in an authorized center with approved medical products. Even so, every medical procedure has a profile of possible effects that it is only honest to share with you.
An aesthetic doctor from the IdB team assesses whether your fold should be treated directly or whether it is better to treat it from the cheek (the cause).





The nasolabial fold is treated with a precise technique because overfilling it produces "chipmunk cheeks"; Instituto de Benito prioritizes repositioning the cheek when it is the cause.
At Instituto de Benito, patient safety comes before any aesthetic goal. We work with audited clinical protocols, medical products with medical CE marking and batch traceability, single-use instruments, dedicated aesthetic medicine rooms and personalized follow-up between sessions. We never delegate a medical-aesthetic procedure to non-medical staff.
Results usually last between 9 and 12 months, depending on the type of product used, facial anatomy and each patient's metabolism.
The nasolabial fold runs from the side of the nose to the corner of the mouth.
Marionette lines appear from the corner of the mouth toward the chin. Although they are different areas, they often appear at the same time and can be treated in the same session.
The price of nasolabial fold treatment is €300 per area.
We perform the treatment at our clinics in Barcelona and Madrid.
In many cases, the nasolabial fold does not appear because of a lack of volume in that area, but because of the descent of the midface tissues, especially the cheek.
That is why treating the cheek can offer a more natural, harmonious and longer-lasting result than filling the fold alone.
Most patients need between 0.5 ml and 1 ml per side, although the exact amount depends on the depth of the fold, skin quality and facial structure. The medical assessment will determine the amount needed to achieve a balanced result.
It depends on the origin of the fold.
If there is a loss of volume or facial support, hyaluronic acid is usually the first option.
If the problem is related to greater skin laxity or tissue descent, a thread lift may be indicated. In some cases, both treatments are combined to optimize the result.
Yes. When the loss of cheek support is corrected in addition to the fold, results can last longer and offer an overall improvement of the face.
When the treatment is performed with a full facial assessment and an appropriate amount of product, the goal is to maintain a natural expression. That is why, in many cases, the fold is not filled directly; instead, the cause behind it is corrected first.
