Questions like “Can ONDA cause harm to the body?” and “I heard some beauty salons are using counterfeit versions of ONDA—is that true?” are becoming increasingly common in online forums. Body microwave lipolysis using ONDA has gained huge popularity in South Korea’s medical aesthetics industry in recent years, thanks to its non-invasive nature and short recovery time. Yet precisely because of its popularity, fake products have started appearing on the market. This article will clarify how ONDA actually works, outline common side effects, and show you how to tell the difference between genuine ONDA PRO devices and other imitation instruments before going to South Korea for treatment. Short answer: Genuine ONDA PRO units have been certified, ensuring safety, but fake versions are circulating on the market. Before choosing a clinic, it’s advisable to verify that the equipment is authentic and that the doctors have the proper qualifications to avoid unpleasant surprises.

What is the principle behind ONDA microwave fat melting?
Straight answer: ONDA uses “Coolwaves technology” to heat the subcutaneous fat layer, causing fat cells to metabolize as a result of the heat. At the same time, it stimulates the production of new collagen in the dermal layer, thereby achieving firming and localized shaping effects. It’s not a traditional liposuction procedure but rather a non-invasive treatment.
Unlike traditional cryolipolysis or laser lipolysis, ONDA’s microwaves allow for precise control over the depth of heating, targeting the fat layer while protecting the epidermis from damage. The treatment usually requires multiple sessions, with results appearing gradually rather than showing obvious changes right after just one session. Be sure to ask your doctor about the recommended number of sessions and intervals during your consultation.
What are the common side effects?
Under normal use, ONDA’s side effects are generally mild and short-lived, including:
- Mild redness and burning sensation at the treatment area, which usually subside within a few hours
- Mild localized swelling, which usually subsides within 1 to 3 days
- Very few people may experience temporary skin sensitivity or stinging.
The “side effect concerns” circulating online often stem not from the ONDA technology itself, but rather from insufficient experience among operators, incorrect energy settings, or the use of unauthorized devices. This is also why it’s so important to choose a clinic with a proper medical background and procedures performed by qualified doctors.
The genuine ONDA PRO vs. counterfeit models
In recent years, many “ONDA-like” devices have appeared on the market. While they may look similar, their technical specifications and safety certifications might not meet industry standards. It’s recommended that patients keep the following points in mind:
- The genuine ONDA PRO is manufactured by the Italian company DEKA, and clinics should be able to provide proof of equipment authorization.
- Reputable clinics are operated by licensed physicians, not cosmetologists or unqualified staff.
- A thorough skin and health assessment should be conducted before the treatment, rather than just getting the procedure right away.
- The price is significantly lower than market rates, so be sure to pay close attention to the equipment and staff qualifications.
During the in-person consultation, you can directly ask whether “this device is an authentic Onda original” and whether “the person operating it is a licensed doctor.” Reputable clinics will generally give clear answers and avoid such questions.

Who is suitable/not suitable for getting ONDA?
ONDA is particularly suitable for those dealing with localized fat accumulation and mild skin laxity who also wish to tighten the affected areas. Common treatment sites include the arms, waist, abdomen, and Thighs. It is generally not recommended for individuals who are pregnant or breastfeeding, those with severe cardiovascular diseases, or those who have metal implants or pacemakers. Whether it’s appropriate for a specific person depends on a doctor’s assessment of their medical history and overall health condition.

Frequently Asked Questions
Q1: Is ONDA effective after just one treatment?
It’s generally not recommended to have the procedure done just once. Most treatment plans involve 3 to 4 sessions spaced about 2 to 4 weeks apart, giving the body time to metabolize the substances and allowing the results to build up gradually. The exact number of sessions should be determined based on the doctor’s assessment.
Q2: Could ONDA make skin sagging worse?
Under proper procedures, ONDA’s microwaves simultaneously stimulate the production of new collagen in the dermis, which theoretically helps tighten the skin and prevents further sagging. However, if the energy level isn’t set correctly or the technician lacks experience, it may affect the results. That’s why it’s crucial to choose a reputable clinic with medical expertise.
Q3: How can I know if the clinic I visit uses genuine equipment?
You can ask to see the original manufacturer’s labels or certification documents for the equipment during your in-person consultation, or check the list of clinics certified by South Korea through official agents in advance, so as to avoid making decisions based solely on what the clinic claims.
Just a quick reminder: your skin might experience mild redness and swelling after the treatment, which usually subsides on its own within a few days.
If you already have severe cardiovascular disease, be sure to discuss your medical history thoroughly with your doctor first.
It’s recommended to ask to see the genuine certification for the equipment during your in-person consultation to ensure the treatment is safe and reliable.
Drinking plenty of water and avoiding spicy foods after the treatment can help accelerate metabolism.
If you have any doubts about the results of the treatment, feel free to schedule another follow-up appointment to discuss it with the director.
