Cavitation

What is cavitation and how does it work?

Cavitation is based on the physical action of low-frequency ultrasound (usually 30–40 kHz) — the ultrasound wave creates microbubbles in the fat cells, and their collapse breaks down the membranes of those fat cells. The released fat content can then be gradually removed by the body via the lymphatic system (it is mainly metabolised through the liver). Unlike liposuction, which is a surgical intervention, cavitation is non-invasive and requires no recovery time.

On the Estonian market, cavitation devices divide into classic 30–40 kHz ultrasound and combined systems, which additionally have radiofrequency (RF) and vacuum massage. The combined approach gives better results — RF heats the skin and stimulates collagen, while vacuum massage improves lymphatic drainage. A quality salon invests in professional-grade devices (not merely the variants meant for home use).

The result emerges gradually — the first changes may be noticed after 3–4 sessions, a significant result after 6–10 sessions. The typical protocol is 1–2 sessions per week (no more often than that, so the body has time to remove the fat content). Since cavitation does not permanently reduce the number of fat cells the way lipo does, it is important to maintain the result with healthy eating and regular physical activity.

Cavitation prices and how a session unfolds

The price of a cavitation session depends on the salon, the device used and the treatment area. Single sessions usually start from 40–80 € per session, while course packages (8–10 sessions) are typically 250–600 € depending on the salon and the grade of the device. Combined sessions (cavitation + RF + vacuum) carry a higher price (60–120 € per session) but usually give better results.

A typical visit begins with a consultation, where the cosmetologist assesses the patient's body contour, the thickness of the fatty tissue and their suitability for cavitation. Cavitation is most effective on the stomach, thighs, buttocks, upper arms and flanks — on small, localised fat pockets that are hard to shift with training and diet. Cavitation is not a weight-loss method and is not suitable in cases of greater obesity (BMI over 30).

A session lasts 30–60 minutes. The cosmetologist applies ultrasound gel to the skin and guides the device's handpiece rhythmically across the treatment area. The patient feels mild warmth and a high-frequency sound. After the session, drinking plenty of water and light physical activity (walking, yoga) are recommended, to encourage lymphatic drainage of the released fats. Salons such as SIM Ilusalong in Tallinn, ProAge Ilukliinik in Tartu and Thaleia Ilusalong in Tartu often offer cavitation together with other body contouring procedures.

How to choose a beauty salon that performs cavitation?

The first check is the salon's operating licence and the cosmetologist's education. Although in Estonia cavitation does not require a medical operating licence from the Health Board (Terviseamet) (since it is not classified as a medical procedure), offering cosmetology services does require a cosmetology business licence. Favour a salon where a thorough consultation is held before the course and where there is experience with this procedure.

Pay attention to the device used. Professional-grade cavitation devices are registered as medical devices (with the CE marking) and support deeper penetration (a better result) than devices intended for home use. Combined systems (cavitation + RF + vacuum) are usually more effective. A good salon will show the patient the manufacturer and model of the device and will speak openly about its capabilities and limitations.

At the consultation the cosmetologist must give a realistic forecast. Cavitation is effective for small and medium localised fat pockets — it is not a weight-loss method and does not solve the problems of large areas. A warning signal is a promise that 10 kg will go in a couple of weeks or that fat pockets will disappear entirely with one session. Favour a salon where it is said openly that the outcome of the course also depends on the patient's own lifestyle (nutrition, water, movement).

Risks, side effects and contraindications

Cavitation is a relatively safe non-invasive procedure, but it does bring real side effects: temporary redness and a feeling of warmth in the treatment area, mild haematomas (especially in sensitive people or when combined with vacuum massage), mild pressure sensitivity in the ears (in some patients, from the sound of the ultrasound), dry mouth and thirst (due to the release of fat content — afterwards it is important to drink plenty of water). More serious complications are rare.

Contraindications include pregnancy and breastfeeding, a pacemaker or other electronic medical devices (ultrasound may interfere with their operation), heart and cardiovascular diseases, blood clotting disorders, severe high blood pressure, kidney or liver disease (since the released fat is metabolised in the liver), an active malignant tumour, autoimmune diseases in an active phase, recent operations (at least 6 weeks beforehand) and menstruation (a relative contraindication, best postponed).

After cavitation, drink plenty of water (at least 2 litres the next day), do light physical activity (walking, yoga) and avoid alcohol for 24 hours (alcohol burdens the liver, which processes the released fat). Combining it with healthy eating and regular physical activity gives the best result. After a full course, maintenance procedures once a month help hold the result.

Cavitation in Estonia's more popular cities

In Tallinn the cavitation service is offered by many beauty salons and body contouring centres, including SIM Ilusalong, whose focus is professional body contouring procedures. In the capital both classic cavitation devices and combined systems (cavitation + RF + vacuum) are available, the latter giving a more complete result.

In Tartu, cavitation is offered by ProAge Ilukliinik, Thaleia Ilusalong and other salons where the cosmetologists have specialised in body contouring procedures. Beauty salons in Pärnu, Narva and the county centres (for example Bella Canella in Valga) mostly cover the basic cavitation procedures. Since a course requires 6–10 visits at 1–2 week intervals, choose a salon according to geographical convenience. For maintaining a longer-term result, a relationship with one salon and one cosmetologist is better — someone who knows how your body is progressing and can adapt the protocol as needed.
