Body mesotherapy consists of microinjections of personalized cocktails (lipolytic, vasoactive, draining and firming active ingredients) into the areas of the body where the aim is to reduce localized fat, improve cellulite or firm the skin.
This is the most requested area. It is used to reduce localized fat and improve mild skin laxity, helping to define the abdominal contour.

In high demand for treating cellulite. It improves skin texture and reduces the “orange peel” appearance.

Indicated for eliminating fat accumulated on the hips, helping to slim the body's silhouette.

It focuses on reducing the well-known “love handles”, slimming the waist and improving the body contour.

One session €80 · The 6-session package has a 10% discount: €432
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.
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 by a licensed aesthetic doctor. It consists of the following steps:

Before treatment, you have a consultation with the aesthetic doctor at Instituto de Benito. The doctor 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. The doctor gives you home-care instructions and schedules your follow-up visits.


Body mesotherapy is indicated for people in good general health who match any of these profiles. Final suitability is confirmed by the doctor after a personalized consultation.
When diet and exercise are not quite enough to eliminate stubborn deposits.
In its different forms (edematous, fibrous or flaccid).
To restore tone and firmness.
As part of a regular anti-cellulite and firming routine.
To boost the elimination of toxins and fluids.
Areas that respond less well to other treatments.

An aesthetic doctor from the IdB team assesses whether dissolving the filler is necessary and is the right indication, deciding the dose and area according to the previous product and the result to be corrected.

Body mesotherapy is one of the most requested treatments, and at IdB it is designed as an individualized medical protocol, never as a generic session.
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.
Body mesotherapy is one of the aesthetic medicine treatments with the longest clinical track record in Europe, and is included by the Spanish Society of Aesthetic Medicine (SEME) in the combined management of cellulite and localized fat. Current medical guidelines emphasize the importance of a differential diagnosis of the type of cellulite (edematous, fibrous or mixed) before choosing the cocktail and the treatment schedule. The success of the treatment depends largely on that initial assessment.
Between 6 and 10 sessions, usually 1 per week, followed by monthly maintenance. The exact schedule is set by the doctor after assessing your case.
Yes, especially when combined with other treatments such as pressotherapy, lymphatic drainage, collagen inducers or radiofrequency.
€80 for a single session. 6-session package €480 (10% discount). Centers in Barcelona and Madrid.
6-10 sessions, usually 1 per week, depending on your goal and response. Monthly maintenance afterward.
Lipolytic therapy focuses specifically on breaking down localized fat (€200 per session, a limited alternative to surgery). Body mesotherapy is broader: it works on cellulite, fluid retention and skin quality as well as fat (€80 per session). They can be combined in comprehensive plans.
Edematous cellulite (with fluid retention) and moderate fibrous cellulite respond best. Severe fibrous and flaccid cellulite need to be combined with radiofrequency or shock waves to see results. The doctor will recommend your plan.
Visible improvement from the 3rd-4th session. The result is consolidated once the full plan is completed. Consistency is key: skipping sessions or stopping halfway gives poor results.
