In brief
Microwave Contouring uses microwave-based energy, delivered at Kaiteki through the Onda platform, to address localised fat, cellulite appearance and skin firmness. Which areas are treatable, and whether any of yours are, is settled by examining the area rather than by naming the concern.

What is Microwave Contouring?
Microwave Contouring is a category of non-invasive body- and face-contouring technology that uses microwave-based energy to act on tissue beneath the skin's surface. At Kaiteki this is delivered using the Onda platform, which the manufacturer refers to as Coolwaves® technology.
It is used on localised fat on areas such as the abdomen, flanks, thighs and arms, on the dimpled appearance of cellulite, and on skin firmness, including the face and jawline. It is not a weight-loss treatment: it treats localised areas, not overall body weight.
How can microwave energy reach fat without burning the skin?
Microwave energy is delivered beneath the skin's surface while built-in cooling helps keep the surface protected during treatment. The energy is intended to act on the targeted tissue, for example localised fat cells or the fibrous bands associated with cellulite, and may also prompt a gradual collagen-remodelling response supporting firmness.
Concerns this treatment addresses
Each of these pages covers what the concern is and every option considered for it, not only Microwave Contouring.
Who should postpone or avoid it
Mention every device or implant at consultation.
- Pregnancy. Treatment is deferred.
- Implants or medical devices in the treatment area.
- Some skin or health conditions, which your doctor goes through with you.
What a session involves
Consultation and assessment
Your first visit is a consultation, not a treatment. The doctor examines the area, decides whether it is treatable, and chooses between Onda for Body and Onda for Face.
The treatment
After the area is examined, a handpiece is moved over it to deliver the energy while the surface is cooled. Most people describe a warming sensation.
In the treatment room
A practitioner moves the handpiece across the patient's abdomen.
A gloved practitioner applies the handpiece to the upper arm area.
A practitioner works under the jaw with the handpiece.
After a session
Downtime is usually limited.
Straight afterwards
Temporary warmth, redness or mild tenderness over the treated area can occur and typically settles.
Most people return to usual activities. The doctor gives aftercare guidance specific to you.
Risks, side effects, and what Microwave Contouring cannot do
Like any energy-based treatment, it carries risks, which are explained before a course is booked.
Common and temporary
Redness, swelling, warmth or tenderness in the treated area.Less common
The energy is thermal, so the risk that matters is overheating one spot. It is managed by keeping the handpiece moving and by treating within what the doctor judges the tissue can take.Pigment change and Malaysian skin
Microwave energy heats tissue beneath a cooled surface rather than targeting pigment, so it does not rely on colour contrast the way a laser does.What it cannot do
- It is not a weight-loss treatment: it treats localised areas, not overall body weight.
- Not every area is treatable. That is settled by examining it, not by naming the concern.
- It is not a single-session treatment. A course is common, and a body area generally takes more sessions than a facial one.
Tell your doctor about every implant or medical device, and your full medical history.
What affects the number of sessions, and the cost
Sessions and cost depend on the areas treated and how you respond. A facial area and a body area take very different amounts of time on the handpiece, so cost follows the areas agreed at consultation.
- The area being treated, body or face.
- The concern being addressed.
- How many sessions the course needs, which depends on your response.

Devices used at Kaiteki
Which platform is used depends on your individual assessment.
Common questions
What device is used at Kaiteki?
The Onda platform, which its manufacturer calls Coolwaves® technology.
Is it painful, and is there downtime?
Built-in cooling protects the surface, and most people describe a warming sensation. Downtime is usually limited.
How many sessions will I need?
A course of several sessions spaced a few weeks apart is common. A body area generally takes more sessions than a facial one, simply because there is more of it.
Is Onda a weight-loss treatment?
No. It addresses localised areas of fat and skin firmness, not overall body weight, and it is not a substitute for weight management.
What is the difference between Onda and Onda Pro?
Onda Pro is DEKA's newer generation of Onda. Both use the same Coolwaves® microwave technology, and Onda Pro has dedicated handpieces for the face and the body. Kaiteki has both, and the doctor chooses the device for the area being treated.
