The anti-wrinkle treatment at Instituto de Benito is an aesthetic medicine procedure based on a medical treatment that temporarily relaxes the muscles responsible for dynamic expression wrinkles (the ones that appear with facial movement) on the forehead, between the eyebrows and around the eyes (crow's feet). It is one of the most requested treatments in aesthetic medicine because it is quick, well tolerated and gives a natural-looking result when performed by an experienced doctor.
Which areas can we treat?
Horizontal forehead lines appear when you raise your eyebrows. Botulinum toxin helps soften these lines while keeping your expression natural and avoiding a stiff look.

This is one of the most frequently treated areas. The vertical lines that form when you frown can make you look angry or tired. The treatment relaxes these muscles and softens your expression, for a more rested-looking face.

These wrinkles appear when you smile or make facial expressions. Botulinum toxin reduces them without losing the expressiveness of your eyes, for a fresher look.

This includes areas such as the barcode lines (upper lip), the corners of the mouth and the chin. Here the application is more precise and personalized, as the aim is to balance your expression without affecting function, improving the overall appearance of the face.


The treatment is carried out entirely in a medical office at Instituto de Benito in Barcelona or Madrid, in an outpatient session that is always planned and performed 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 should be clean and free of creams. Your doctor will tell you whether you should avoid any medication in the days beforehand to minimize bruising, and will discuss with you anything 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.


Standard treatment €390 · Touch-up treatment €275.

Patient safety comes before any aesthetic result. Anti-wrinkle 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. |
| Neuromuscular disease | Myasthenia gravis and similar conditions are a contraindication for botulinum toxin. |
| Treatment with aminoglycosides | They can increase the effect of the toxin; the timing of the treatment is assessed. |
Anti-wrinkle treatment is safe when performed by a licensed doctor in an authorized center using approved medical products. Even so, every medical procedure has a profile of possible effects that it is only honest to share with you.
The team tailors each treatment to the patient, with the aim of a natural result.





Anti-wrinkle treatment is one of the most prescribed procedures at Instituto de Benito, and we apply a strict protocol for dosing, dilution and batch traceability in every session, without exception.
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.
The product used in anti-wrinkle treatment is authorized by the Spanish Agency of Medicines and Medical Devices (AEMPS) and by the European Medicines Agency (EMA) for aesthetic use in adults, with decades of accumulated clinical evidence. The Spanish Society of Aesthetic Medicine (SEME) lists it among the most studied facial aesthetic medicine treatments and sets out specific guidelines on dosing, technique and informed consent, which we follow in every session. It is only administered on prescription and applied directly by a doctor.
The effect of anti-wrinkle treatment lasts between 4 and 6 months. To maintain the result, we recommend repeating the session every 4-6 months.
The first effects are visible after 3-7 days, with the optimal result 14 days after the session.

Anti-wrinkle treatment temporarily relaxes the muscles responsible for dynamic wrinkles (the ones that appear with facial movement). Hyaluronic acid filler adds volume and fills static or structural wrinkles. They are complementary: many patients combine the two. Anti-wrinkle treatment works on the forehead, between the eyebrows and on crow's feet; hyaluronic acid on folds, under-eye circles, lips, cheekbones
According to the scientific literature compiled by the SEME, more than 95% of patients see a clear improvement in dynamic wrinkles 14 days after treatment. A small proportion (≈1-3%) are less sensitive to the product because they develop antibodies; in those cases the doctor adjusts the regimen.
The doctor assesses your natural facial movement during the consultation (you will be asked to raise your eyebrows, frown and smile) and decides the injection points and the dose based on the strength of your muscles, the depth of your wrinkles and your aesthetic goal: a subtle preventive effect, moderate softening or a more marked result.
The optimal result appears after 14 days. If you have a wedding, a professional event or a photo shoot, plan your session 2-3 weeks in advance so that the initial swelling (minimal, lasting hours) has already passed and the effect has settled.
