Reducing localised fat with high-intensity focused ultrasound. It destroys fat cells selectively and permanently — without surgery, without anaesthetic and without downtime.
In short
Focused ultrasound with Liposonix technology reduces localised fat on the abdomen, flanks or thighs without surgery or needles. A session takes 60–90 minutes with no downtime, and the result lasts 12–18 months; the price is set at the assessment. Treatment is performed by Dr. Rubén Bermejo Pérez, a registered aesthetic physician (COMB no. 63226), at Clínica Sagrada Família, Barcelona.
Dr. Bermejo explains how focused ultrasound removes localised fat in small areas, without surgery.
Medical judgement
“Focused ultrasound doesn't suck out or cut. It destroys the fat cell with millimetre precision — and the body removes it on its own over the following weeks.”Dr. Rubén Bermejo Pérez
How it works · Focused ultrasound for fat
Localised fat, treated where it is.
Focused ultrasound designed for fat.
At the focal point, fat cells break down and the body removes them.
It isn't immediate. Treated fat cells don't come back, but habits still count.
What it treats
The abdomen is where this treatment gives the most consistent results. Ultrasound reaches the subcutaneous fat layer at a precise depth of 1.3 cm — destroying fat cells without affecting the skin or nearby tissue. Volume reduces gradually over 8–12 weeks as the body naturally removes the damaged cells.
The inner and outer thighs and saddlebag area are where fat resistant to exercise and diet can be treated very effectively. The device's precision allows safe work near sensitive structures.
The lower back, flanks and love handles are fat deposits that respond very well. You don't see them until you look at yourself side-on or from behind — so they have a significant visual impact on your silhouette even if they're not the first areas you think of.
It can be used as a non-invasive alternative to liposuction in patients with moderate localised fat who don't want or can't have surgery. The result isn't as dramatic as surgery but is permanent for the destroyed fat cells — with zero downtime and no anaesthetic risks.
No filters
It's a single session and the result comes gradually as your body removes the treated fat. This is what the studies say.
Treatment day
The area is treated in a single session. You feel warmth and the occasional prick while the energy is applied.
Following days
The area may be tender, slightly swollen or bruised. You carry on as normal.
4–8 weeks
Your body naturally removes the treated fat. You notice the change in how your clothes fit.
12 weeks
Waist reduction is usually between 2 and 4 cm at 12 weeks. Keeping your weight stable is key.
What it doesn't do: it isn't a weight-loss or obesity treatment: it's designed for localised fat in people with a stable weight.
The practical side
Everything you need to know before your consultation. No small print.
Destroyed fat cells don't regenerate. The result holds with a stable weight. One maintenance session a year is enough.
It varies with the area and its size. The whole abdomen takes longer than a small area.
Possible redness and warmth for the first few hours, and mild tenderness for 24–48 h. Normal life straight away.
It depends on the areas treated and the number of pulses needed. It is set at the assessment.

In the consultation we study your case, talk about what you want and set the goals together. If you don't need treatment, I'll tell you that too.

It's a high-intensity focused ultrasound (HIFU) device designed specifically to destroy localised fat. Unlike other HIFU devices, it has a fixed focal depth of 1.3 cm — the depth of the subcutaneous fat layer — which allows very high precision and selectivity. The destroyed fat cells are removed naturally by the body over the following weeks.
Liposuction physically removes fat through surgery — the result is more dramatic and immediate but involves general or epidural anaesthesia, weeks of recovery and surgical risks. Focused ultrasound destroys fat cells without surgery — the result is more gradual and moderate, but with no recovery or anaesthetic risks. I'll explain which makes more sense for you at the assessment.
In the reference trial the average waist reduction was about 2 cm at 12 weeks — but it varies a lot with the thickness of the fat layer, the area treated and each patient's metabolism. The goal isn't a specific number of centimetres but reshaping the silhouette. The best results are in patients with moderate localised fat and a stable weight.
There's discomfort during the session — intense warmth and pressure with each pulse. Intensity varies with the area and fat thickness. The abdomen is usually more tolerable than the flanks or thighs. No anaesthetic is needed. Most patients describe it as uncomfortable but tolerable.
The result starts to show between 4 and 6 weeks — that's how long the body takes to remove the destroyed fat cells. The maximum result shows at 10–12 weeks. During that time it's important to keep your weight stable.
No. Destroyed fat cells are removed for good — they don't regenerate. However, if you gain weight, the remaining fat cells in the area and elsewhere can grow. That's why the result holds best with a stable weight.
In most cases a single session gives a visible, significant result. Areas with more fat may need a second session at 3–4 months, once the first result has fully settled. One maintenance session a year is recommended.
