About the treatment
Onda Pro is a non-invasive body contouring device that uses Coolwaves, a form of microwave energy, to target the fat layer beneath the skin. Microwaves are absorbed mainly by fat tissue, with a smaller share reaching the deeper skin, so one treatment can work on fat, cellulite and skin laxity together.
Three handpieces let our team match the treatment depth to the area, from the neck and jawline to the abdomen and thighs.
Body concerns
Onda Pro is commonly used where stubborn fat, skin firmness and texture overlap. Our Medical Team will assess which concerns apply to you and plan the handpieces and areas to match.
Localised fat that remains despite a healthy diet and exercise.
Dimpled skin, commonly on the thighs, buttocks and hips.
Mild to moderate loss of firmness on the body.
Fat and loose skin around the abdomen after pregnancy, once cleared by your doctor.
Fullness under the chin, treated with the smaller handpieces.
Softened contours along the lower face and jawline.
Coolwaves technology
Coolwaves is the name DEKA, the Italian manufacturer of Onda Pro, gives to the device’s microwave energy. It is delivered at a frequency of 2.45 GHz, which passes through the skin and is absorbed mainly in the fat layer beneath it. A cooling system in the handpiece keeps the skin surface cool throughout the session.
Onda Pro has three handpieces, each focusing this energy at a different depth. Select one to see where its energy is concentrated and which areas it is used for. More than one handpiece may be used in the same session.
Handpiece selection and settings are decided by our Medical Team after assessing your body.
Focuses energy in the deeper skin of the lower face and neck.
Used for: skin tightening along the jawline and neck.
Reaches superficial fat under the chin and on areas where the fat layer is thinner.
Used for: double chin, upper arms, and fat combined with skin laxity.
Reaches deeper fat layers on larger areas of the body.
Used for: abdomen, flanks, thighs and buttocks.
1
Coolwaves energy passes through the skin and is absorbed mainly by the fat layer, while the handpiece continuously cools the skin surface.
2
Heat damages targeted fat cells, which the body clears gradually through its natural processes over the following weeks.
3
Heat reaching the deeper skin and connective tissue may prompt collagen remodelling, helping skin look firmer and smoother.
Treatment areas
Onda Pro can treat most areas where stubborn fat, cellulite or loose skin tends to collect. Each area of about 15 × 15 cm takes around 10 to 15 minutes.
Illustration only, not a patient. Areas on the back of the body, such as the buttocks and bra line, are marked from the front for reference. Suitable areas are confirmed by our Medical Team after assessment.
Treatment options
TruGlow offers more than one way to address body fat and loose skin. This overview explains how they differ.
| Treatment | How it works | Commonly used for | Typical recovery |
|---|---|---|---|
| Onda Pro This treatment | Microwave energy heats fat cells while the skin surface is cooled | Stubborn fat, cellulite and loose skin | Most people resume usual activities the same day; mild redness or tenderness may occur |
| Clatuu fat freeze | Controlled cooling of pinchable fat pockets | Localised fat bulges | Temporary numbness, redness or tenderness |
| MPT body tightening | Focused ultrasound (HIFU) delivered to set depths | Mild to moderate skin laxity and fat | Most people resume usual activities the same day |
| The Weight Management Suite | A doctor-guided programme that can include body composition analysis, nutritional counselling, exercise advice and, where suitable, medication | Overall weight management rather than specific areas | No procedure recovery; ongoing follow-up with our team |
Our Medical Team may recommend one treatment or a combination, depending on fat thickness, skin quality and your goals. If loose skin is your main concern, see our skin tightening treatments.
Suitability
Onda Pro is a body contouring treatment, not a weight-loss treatment. Please share your full medical history during consultation so our Medical Team can advise whether it is appropriate for you.
Your visit
From assessment to follow-up, each step is planned around your body and goals.
Step 1
Our Medical Team reviews your medical history, assesses fat thickness and skin quality, and recommends the handpieces, areas and number of sessions.
Step 2
The area is marked and cleansed, and a thin layer of oil is applied so the handpiece glides smoothly. Numbing is not usually needed.
Step 3
The handpiece moves continuously across each area for about 10 to 15 minutes while its cooling system protects the skin. You may feel warmth and a brief prickling sensation.
Step 4
Mild redness, warmth or tenderness may occur and usually settles within hours to a few days. Most people return to normal activities straight away.
Timeline
Onda Pro results build in stages rather than appearing straight after treatment. Heat from each session damages the targeted fat cells, which the body then breaks down and clears through its natural processes over the following weeks. At the same time, warmth reaching the deeper skin prompts collagen to remodel.
Skin may start to look firmer within a few weeks, while fat reduction is usually more noticeable 1 to 3 months after your course, as the effect of each session adds up.
After each session
Day 0 to 3
Warmth, redness or tenderness may be felt and usually settles quickly.
Treatment course
Weeks 0 to 16
Most plans involve 3 to 4 sessions spaced about 3 to 4 weeks apart.
Progressive change
Weeks 4 to 12
Contours may look more defined and skin smoother as fat is cleared and collagen remodels.
Maintenance
Beyond 3 months
A balanced diet, regular exercise and a stable weight help maintain results.
Results vary between individuals and depend on factors including fat thickness, skin quality, lifestyle and the number of sessions.

FAQs
Not sure whether Onda Pro or another body treatment suits you? Our team can help.
Onda Pro delivers Coolwaves microwave energy through the skin into the fat layer. The energy heats and damages targeted fat cells, which the body then clears gradually. Heat reaching the deeper skin may also support collagen remodelling. A cooling system in the handpiece protects the skin surface during treatment.
Onda Pro is designed to reduce localised fat, improve the look of cellulite and firm loose skin. How well it works varies between individuals. Most people need a course of sessions, and changes develop gradually over 1 to 3 months. It tends to suit people who are close to their target weight and have realistic expectations. Our Medical Team will advise during your consultation whether you are likely to benefit.
Onda Pro is the updated version of the Onda system by DEKA. Both use Coolwaves microwave energy. Onda Pro comes with three handpieces, Pocket, Shallow and Deep, so treatment can be matched to smaller areas such as the double chin as well as larger body areas.
Most people feel warmth and a brief prickling or stinging sensation as the handpiece moves. Numbing is not usually needed, and settings can be adjusted during the session for comfort.
Most people return to work and usual activities the same day. Some redness, warmth, tenderness or mild swelling may occur and usually settles within hours to a few days.
Most plans involve 3 to 4 sessions spaced about 3 to 4 weeks apart. The number depends on the areas treated, fat thickness and skin quality, and will be advised by our Medical Team after assessment.
Some people notice firmer-looking skin within a few weeks. Fat reduction develops gradually as treated fat cells are cleared, with changes usually seen over 1 to 3 months. Results vary between individuals.
Fat cells that have been treated and cleared by the body are not replaced in the same way. However, the remaining fat cells can still grow if you gain weight, and skin continues to age naturally. A balanced diet, regular exercise and a stable weight help maintain your results. Some people choose maintenance sessions as advised by our Medical Team.
Common body areas include the abdomen, flanks, upper arms, thighs, buttocks and bra line. On the face, the smaller handpieces can be used for the double chin, jawline and neck.
Yes, cellulite is one of the concerns Onda Pro is used for. By working on the fat layer and the connective tissue beneath the skin, it may help the skin surface look smoother. Cellulite has several causes, so our Medical Team will advise on realistic expectations.
No. Onda Pro is designed to contour specific areas of stubborn fat and loose skin. It is intended for people who are close to their target weight. For support with overall weight, see The Weight Management Suite.
Fat freezing uses controlled cooling on pinchable fat pockets. Onda Pro uses microwave energy that can also reach firmer fat and work on cellulite and loose skin in the same session. Our Medical Team can advise which suits your concerns.
Both are non-invasive. HIFU, such as our MPT body tightening, uses focused ultrasound delivered to set depths and is mainly used for skin laxity. Onda Pro uses microwave energy that is absorbed mainly by fat, so it is used for stubborn fat and cellulite as well as loose skin. Our Medical Team can advise which suits your concerns.
In some cases, yes. Depending on your assessment, our Medical Team may suggest another treatment alongside Onda Pro, or for a different area. Any combination is planned around your goals, skin quality and medical history.
The cost depends on the areas treated and the number of sessions recommended. Please contact our team for current pricing after your assessment.
