What is ONDA Body?

ONDA Body is a body contouring device that delivers microwave energy, branded as Coolwaves, into the layer of fat under the skin. The energy is designed to concentrate in fat tissue while the skin surface is cooled, so it can heat fat cells and the connective tissue around them without cutting or suction.

Because microwave energy behaves differently from the radiofrequency or ultrasound used in many other devices, ONDA is often described as working on two layers at once: reducing localized fat volume and improving the firmness and texture of the skin above. At Re:berry, ONDA sits in the body menu alongside Ulthera Body, Vacumed and Revinas, and it is also used on the face as ONDA Face Lifting.

How does Coolwaves microwave technology work?

Microwaves at the frequency ONDA uses are absorbed more by fat than by water-rich skin. In simple terms, the handpiece warms the fat layer from within while a cooling system protects the epidermis. Heated fat cells can be damaged and then cleared gradually by the body's natural processes over the following weeks.

Fat layer: targeted heat aims to reduce the volume of stubborn, diet-resistant fat.
Connective tissue: the warmth may stimulate collagen in the fibrous septa, which is why ONDA is also used for cellulite.
Skin surface: continuous cooling keeps the treatment tolerable and helps protect the skin.

Who is ONDA Body suitable for?

ONDA Body typically suits adults who are near a stable weight but have specific areas that do not respond to diet and exercise. It is a shaping treatment, not a weight-loss method, so the clearest improvements tend to appear where there is a soft, pinchable layer of fat.

Common treatment areas

Lower and upper abdomen, including post-pregnancy softness
Flanks, often called love handles
Inner and outer thighs and the area under the buttocks
Upper arms and bra-line fat
Areas where cellulite dimpling is visible

When ONDA may not be appropriate

A doctor will usually advise against or postpone ONDA if you are pregnant, have metal implants or a pacemaker near the area, have an active skin infection, or have certain circulatory or bleeding conditions. Very thin fat layers or significant loose skin may respond better to other approaches, which is why diagnosis comes first.

What happens during an ONDA Body session in Hongdae?

Consultation: a doctor assesses fat thickness, skin laxity and your goals, then decides whether ONDA alone or a combination plan makes sense.
Marking and preparation: the area is cleaned and mapped so energy is distributed evenly.
Treatment: the handpiece glides over the skin in passes. Most people feel deep warmth, sometimes with brief hot spots that the operator manages by adjusting settings.
After the session: you can usually dress and go straight back to sightseeing, work or class.

No numbing cream or anesthesia is normally needed. Many visitors staying around Hongdae fit a session into an afternoon and walk out to the Hongdae streets or the Gyeongui Line Forest Park afterwards.

How many sessions do you need, and how long do results last?

Most plans involve 2–4 sessions spaced about four weeks apart, though the number depends on the area, fat thickness and how your body responds. Because the body clears treated fat gradually, changes are usually assessed 8–12 weeks after a session rather than immediately.

Fat cells that are cleared do not typically return, but the remaining cells can still enlarge with weight gain. Keeping a stable weight, staying active and drinking enough water help maintain results. Results vary by individual. For a more detailed breakdown, see how many ONDA Body sessions you may need.

What are the side effects of ONDA Body?

ONDA is generally well tolerated, but it is still a medical treatment. Commonly reported effects include:

Redness and warmth for a few hours
Tenderness, a bruised feeling or mild swelling for several days
Temporary numbness or tingling in the treated area
Rarely, small burns or firm nodules, which should be reported to the clinic promptly

Tell the doctor about any medications, implants and recent procedures during the consultation so the plan can be adjusted to your situation.

Can ONDA Body be combined with other treatments?

Re:berry's approach is to design a combination rather than rely on one device. ONDA is sometimes paired with Berry Slim, the network's contour injection, for areas that need extra fat-targeting support. For lower-body heaviness linked to fluid retention, circulation-focused programs such as Vacumed may be planned between ONDA sessions. If loose skin is the main issue, ultrasound tightening may be considered. The doctor will explain how combinations are sequenced and spaced.

How much does ONDA Body cost at Re:berry Hongdae?

Pricing depends on the area, the amount of energy used and whether you choose a single session or a course. Your plan and its cost are confirmed in writing at consultation, before any treatment begins. To check availability, book via the channels on our Booking page, and see Location & Hours for the branch address and opening hours.

Does ONDA Body hurt?

Most people describe ONDA Body as deep warmth with occasional hot spots rather than pain. The cooling system protects the skin surface, and the operator can adjust energy if an area feels too intense. Anesthesia is not usually required, and you can generally return to normal activities right away.

Can I exercise after ONDA Body?

Light activity such as walking is usually fine on the same day. If the area feels tender, many doctors suggest waiting a day or two before intense workouts. Staying active and well hydrated during your course may support the gradual changes that follow each session.

Is ONDA Body the same as CoolSculpting?

No. CoolSculpting freezes fat cells, while ONDA Body uses microwave energy to heat them. ONDA also aims to tighten skin and improve cellulite in the same session. Which approach suits you depends on fat thickness, skin quality and the area, so a doctor's assessment helps decide.

Can tourists complete an ONDA course in Seoul?

A single session fits easily into a short trip, but a full course is spaced about four weeks apart, so it suits people who live in Seoul or visit regularly. Visitors can start at Re:berry Hongdae and ask about following up at another branch of the network.
