About

What is Onda Body Contouring?

Onda Body Contouring is the body application of DEKA's Coolwaves™ system, which delivers microwave energy at 2.45 GHz through a dedicated body handpiece. It is the same platform behind our facial Onda lifting treatment, run with a larger applicator and a larger energy budget: the published body session here is measured at 80 kJ.

Two details in that description are worth pausing on, because they are what people usually get wrong when comparing body devices. The first is the energy type. Microwaves are not radiofrequency and not laser light; they are their own band, and the reason DEKA built a platform around them is that they interact with tissue on their own terms, and not as a stronger version of something else.

The second is the unit of sale. A session here is not sold as “one abdomen” or “one hour” but as a quantity of delivered energy, counted in kilojoules. That is deliberate: it lets your director spend more of the budget where the tissue calls for it and less where it does not, and it lets you see exactly what you are paying for instead of trusting an unmeasured pass with a handpiece. Change from body work of this kind is gradual, builds over the weeks that follow, and differs from person to person.

Treatment Areas

Where the body handpiece works

Areas are chosen at diagnosis by where soft fullness and slackness actually sit, and the kilojoule budget is divided accordingly.

01

Abdomen and the flank line

The most requested body zone, and the one where the difference between soft fullness and slackened skin is easiest to feel with a hand and hardest to judge from a photograph.

02

Upper arms

The back of the upper arm, where skin quality often bothers people more than volume does. A frequent request before weddings and summer travel.

03

Thighs

Inner and outer thighs, including areas where the surface looks dimpled instead of simply full. Those two are assessed separately, because they are different problems.

04

Buttock & hip line

The upper buttock and hip transition, treated for firmness of the outline instead of for size, and usually planned alongside the thigh.

Wherever the area, the framing is the same: this is contour and firmness work on a localised zone. It is not weight management and does not substitute for it.

Body vs Face

One platform, two jobs

Facial Onda and body Onda share the Coolwaves™ source. Almost everything downstream of it differs.

POINT 01

A dedicated body handpiece

The body applicator is built for broad, curved surfaces such as the abdomen and thigh, where coverage and consistent contact matter more than the fine control a jawline needs. Swapping handpieces is not a formality — it changes what the treatment is for.

POINT 02

A larger energy budget

Body areas are simply bigger, so the standard session here is quoted at 80 kJ, well above the budget a face is planned around. Comparing the two prices without comparing the kilojoules is comparing nothing at all.

POINT 03

A 2.45 GHz band of its own

Coolwaves™ operate at 2.45 GHz, a distinct energy band. If you are cross-shopping body devices, this is the specification worth writing down, because “energy-based body contouring” covers several technologies that do quite different things.

If you already had facial Onda

Patients who have had Onda lifting on the face often ask whether the body version feels the same. Broadly yes, in the sense that the sensation is warmth under a moving applicator, with nothing sharp involved, and there is no needle either way. The differences are scale and duration: a body area takes longer to work through, the warmth is spread over more surface, and the session is planned as a much larger quantity of energy. Knowing how your skin responded on the face is genuinely useful information for planning the body, so mention it at consultation.

Where Onda body work stops

It is not a weight-loss treatment, and no body device is. We publish no centimetre or kilogram figures on this page, because any number offered before your body has been assessed is a guess, and outcomes across the published research vary widely between individuals. Nor does Onda replace surgery where a large volume of tissue is the issue: where that is what your diagnosis shows, we do not recommend a course of sessions, and you hear that at the assessment.

How an Onda body plan is put together

01 — THE FULL ARSENAL

A body device is one option among several

Body work here sits alongside the face and body options held in every other category at this clinic, so no single machine has to justify its purchase through your booking. Where the described problem turns out to be a large volume of tissue, or body weight, we do not recommend an Onda course and say so at the assessment. What does get booked carries one number: ₩650,000 (≈ $465) for 80 kJ.

02 — DIAGNOSIS FIRST

Separating soft tissue from slack skin

Your assessment uses the EVE Muse 3D scan and five-light-source AI analysis alongside a hands-on examination of the area. How much of the fullness is soft tissue and how much is slackness in the skin above it is the finding that changes the plan, because the two are budgeted differently.

03 — DIRECTOR-PERFORMED

Director-performed, kilojoule by kilojoule

The session is performed by our directors, who decide where the energy budget is spent as they work, without a fixed template. On a curved body surface, that judgement is most of the treatment.

What a kilojoule figure lets you compare

Body treatments are the easiest place in aesthetic medicine to sell a long, vague course. Quoting a published rate against a stated kilojoule figure removes most of that vagueness: you know what is being delivered, you can compare it, and a second session stays a decision you make with information, since no obligation was signed in advance. If your diagnosis suggests the area will not reward more energy, we say so at the review and point you to something that suits you better.

How much does Onda body contouring
cost in Seoul?

At Dear Clinic in Cheongdam, an 80 kJ Onda body session is ₩650,000 (≈ $465) — the same published rate for locals and international visitors. The kilojoules are the unit: how they are distributed across your abdomen, arms, thighs or hip line is decided at diagnosis, and the quote is confirmed with you before anything begins.

Every planEVE Muse 3D + AI assessment · doctor consultation · aftercare guidanceincluded

Published rate as of September 2026. Nothing is pre-sold as a multi-session package: you book one session at a time, and whether a second is worth your money is a conversation held after we have both seen how the area responded. The facial version of this platform is priced separately on the Onda lifting page, and all published rates are on the full price list. Appointments are available every day, including Sundays and public holidays.

Caution

Aftercare after a Coolwaves body session

Warmth and mild redness over the treated area are normal and usually settle within hours.
The area can feel tender or slightly firm to the touch for a few days as tissue responds.
Drink water normally and keep moving; ordinary activity is encouraged after this treatment.
Hold off on saunas, very hot baths and intense heat exposure for the period your director specifies.
Tell us if tenderness, swelling or any lump persists beyond the window we described at your session.

FAQ

Onda body contouring, answered

Is Onda body contouring worth it?
It suits a specific brief: a localised area that stays soft or slack despite a stable weight, treated without needles or surgery. It is not a way to lose weight, and it will not restructure a body shape. Whether the area you have in mind is likely to reward the energy is exactly what the diagnosis is for, and you will get a direct answer before booking.
How much does Onda body contouring cost in Seoul?
An 80 kJ session at Dear Clinic is ₩650,000 (≈ $465), the same published rate for locals and international visitors. The price is tied to the delivered energy rather than to a time slot or a body part, so you can compare it meaningfully against other quotes. Nothing is pre-sold as a package.
What are Coolwaves, and how are they different from radiofrequency?
Coolwaves™ are microwaves delivered at 2.45 GHz by DEKA's Onda platform. Microwaves sit in a different band from radiofrequency and are not laser light at all, which is why the treatment is categorised on its own and not as another RF body device. If you are comparing machines, the frequency and the energy delivered are the two specifications worth recording.
Is this the same machine as the facial Onda treatment?
Same platform, different handpiece and different energy budget. Facial Onda lifting uses the platform's face configuration on a much smaller area; the body treatment uses a dedicated body handpiece and is quoted at 80 kJ. If you have already had the facial treatment here, tell your director — how your skin responded is useful information for planning body work.
Will I lose centimetres or weight?
We publish no centimetre or weight figures for this treatment, and any number quoted to you before your body has been examined is a guess. This is contour and firmness work on a localised zone; weight management is a different problem with different tools. Published research reports varied outcomes between individuals. What you can expect is a measured amount of energy delivered to an agreed area, and a review of what actually changed.
How many sessions will I need?
That is set at consultation and reviewed as you go. Because sessions are sold one at a time, the decision about a second is made after both of us have seen how the area responded to the first. Body tissue also changes gradually, so an assessment point some weeks out is more informative than one taken the following day.
Does it hurt?
Most people describe warmth building under a moving applicator, sometimes reaching a hot but manageable peak over firmer areas. There are no needles and no anaesthetic is normally needed. Tell your director if a zone becomes uncomfortable; the pace and the way the energy is distributed can be adjusted while the session runs.
Is there downtime?
Very little for most people. Warmth and mild redness over the area settle within hours, and tenderness or a slightly firm feel can linger for a few days. Ordinary activity, work and light exercise usually continue the same day; saunas, very hot baths and intense heat exposure wait for the period your director specifies.
When will I see a difference?
Change from this kind of body work is gradual and builds over the weeks after a session as tissue responds, and not in the minutes after you stand up from the bed. Photographs at agreed intervals are more useful than a mirror check on day two, and your assessment points are set with you at the start.
Can it be combined with other body treatments?
Sometimes, and the sequencing matters more than the combination. Different body approaches ask the tissue to recover in different ways, so your director paces them instead of stacking them in one visit. What can sensibly be combined, and in what order, is decided at diagnosis for your specific plan.
Who should not have this treatment?
Body energy treatments are not suitable for everyone, and pregnancy, certain implanted devices and some medical conditions are among the reasons a session may be declined or postponed. Bring your medical history and any current medication to the consultation; screening for suitability happens before anything is booked.
I am visiting Seoul — can an 80 kJ session fit a short trip?
Comfortably. Assessment and consultation take the first part of the visit, and the session itself can follow the same day once the area is healthy and your director confirms suitability; how long the session runs depends on the size of the area and how the 80 kJ is spread across it, and that is confirmed when your plan is agreed. There is no bruise to schedule around and no needle, so a flight the next morning is not a problem, and the warmth and mild redness settle within hours. Everyone pays the same published rate, weekends and public holidays are ordinary booking days, and the form below is answered in English within one business day with no deposit taken to hold the slot.

Scientific Evidence

Science behind microwave body contouring — peer-reviewed references

The published literature on microwave-based body contouring is small. We have found three indexed, peer-reviewed papers worth listing, and we list all three rather than selecting the most flattering: a nine-month follow-up on abdominal localised adiposity, a clinical-evidence paper on localised adiposity, skin laxity and cellulite, and a German-language report on subcutaneous fat reduction with a microwave-based body contouring system.

Three papers is an early evidence base and we say so plainly. They carry verifiable DOIs from indexed journals, and they describe the technology; what your own area does is assessed at your diagnosis and reviewed afterwards.
