Onda Lifting: How the 2.45 GHz Microwave Treatment Works
Question: What is Onda lifting and how does it work?
Short answer
Onda lifting is a non-surgical treatment using a device made by the Italian company DEKA that delivers 2.45 GHz microwaves (Coolwaves) beneath the skin. The manufacturer explains that this energy acts on the subcutaneous fat layer and dermal collagen, and it is used on both the face and body. Research evidence is still small in scale and reactions vary from person to person, so suitability and the recovery process are checked during the consultation.
Key points
- Made by DEKA in Italy; the technology is called Coolwaves
- Uses 2.45 GHz microwaves with integrated cooling
- The manufacturer says it acts on the fat layer and dermal collagen
- Evidence on long-term effects and safety is described as still limited
- CELITA Clinic offers Onda for the face and Body Onda
What kind of energy does Onda lifting use?
Onda lifting uses a handpiece that emits 2.45 GHz microwaves together with an integrated cooling system.
The device is made by DEKA, based in Calenzano near Florence, Italy, and the manufacturer calls this microwave technology Coolwaves. Published papers also describe it as using a 2.45 GHz microwave handpiece with integrated cooling.
Whereas HIFU (ultrasound) lifting focuses ultrasound energy on a point and radiofrequency (RF) lifting uses electrical current, Onda uses a different type of energy: microwaves. This only means the type of energy is different, not that one is superior, and the choice depends on skin condition.
| Handpiece | Main use described by the manufacturer |
|---|---|
| Deep | Localized fat over large areas |
| Shallow | Cellulite, skin laxity, under the chin |
| Facial contouring, tightening |
How does the manufacturer describe how Onda works?
The manufacturer explains that Coolwaves selectively target subcutaneous fat cells and stimulate contraction and production of dermal collagen.
DEKA explains that Coolwaves act on fat cell membranes, also affect the connective tissue between fat lobules in cellulite, immediately contract dermal collagen fibers and stimulate new collagen production. The manufacturer also explains that, unlike radiofrequency, which mainly disperses energy in the superficial layers, Coolwaves are preferentially absorbed by fat tissue.
This is the manufacturer's description, and actual reactions differ from person to person depending on skin thickness, the amount of fat and skin firmness.
What Onda handpieces are there?
The manufacturer explains that three handpieces, Deep, Shallow and Pocket, deliver energy at different depths.
According to the manufacturer, Deep is used for localized fat over large areas, Shallow for cellulite, skin laxity and the area under the chin, and Pocket for facial contouring and tightening. The manufacturer explains that 5°C contact cooling protects the surface of the skin during treatment.
Which handpiece is used on which area is decided by the medical team based on the analysis results and your goals.
What does the research say about Onda lifting, and what are the side effects?
Research on Onda is still small in scale, and an international advisory board consensus also states that evaluation of long-term effects and safety is lacking.
In a small study in which 19 adults with abdominal fat had 3 treatments 4 weeks apart, abdominal circumference decreased by an average of 3.80 cm after 3 months, and no severe pain during treatment was reported. A retrospective study of 171 East Asian patients reported that the microwave-based device showed faster early improvement at 1 month, while HIFU showed greater sustained improvement at 3 months.
The same study reported only mild, temporary side effects with both methods, but the degree and duration of reactions such as redness and swelling vary from person to person. At CELITA Clinic, the expected recovery process (downtime) is explained during the consultation.
What is its approval status in Korea, and how does CELITA Clinic use it?
Onda devices are approved as medical devices by the MFDS in Korea, and CELITA Clinic offers Onda lifting for the face and Body Onda.
According to the MFDS product search, ONDA is registered as import certification 22-4482 (product name microwave stimulator, Class 2, 2022-10-12), ONDA SMART as import certification 24-369 (2024-07-26), and ONDA PRO as import approval 26-28 (product name general-purpose electrosurgical unit, Class 3, 2026-01-26). This is as of 2026 and may change.
At CELITA Clinic, people under 19 (international age) can also be consulted about lifting treatments such as Onda lifting with consent from a parent or guardian. Before treatment, skin condition is checked with AI skin analysis and an ultrasound probe.
FAQ
Is Onda FDA cleared?
No clearance record under the Onda name was found in the FDA 510(k) database. In Korea it is approved as a medical device by the MFDS, and the approval information is as of 2026.
Is Onda only used on the face?
Onda is used not only on the face but also on body areas such as the abdomen. CELITA Clinic offers body treatments separately as Body Onda, and whether it suits each area is checked during the consultation.
When can I wear makeup on the day of Onda treatment?
CELITA Clinic's general aftercare advice recommends gentle face washing and makeup 2 to 3 hours after treatment. If redness remains, follow the medical team's advice for your condition.
