Last year, because of the extra fat on my chin and those stubborn deposits around my waist that wouldn’t go away no matter how much I exercised, I flew to Seoul. A friend suggested, “Go get ONDA treatment—it’s super popular in South Korea.” So I started doing my research. To my surprise, there were several clinics in Gangnam claiming to offer ONDA treatments, all run by the same director, with each clinic’s official website stating things like “DEKA original certification” and “no recovery time needed.” I was really confused—since they all used the name ONDA, which one should I choose? Would it be a waste of time if I picked the wrong one? This is my honest review after visiting three clinics and doing thorough research. There are no rankings or recommendations here—just guidance to help you decide based on what part of your body you want to improve.

I. What exactly is ONDA? Understand it first before making a choice.
Many people think ONDA is a “weight loss device,” but in reality it focuses on combining fat dissolution with skin tightening. It’s a microwave therapy device produced by Italy’s DEKA company, operating at a frequency of 2.45GHz — exactly the frequency that water within fat cells absorbs, heating those cells to around 43–45°C and triggering apoptosis (the cells dying on their own and being eliminated through lymphatic metabolism). At the same time, the dermal layer heats up, causing Collagen to contract and thus tightening the skin. It has already received certifications from CE, KFDA, and FDA.
It differs from other procedures we often hear about in this way:
• Compared to CoolSculpting: While CoolSculpting uses freezing, HIFU uses heating. ONDA adds an extra “skin tightening” effect, so you lose weight without sagging.
• Compared to Thermag
e/HIFU: The latter two primarily target firming the dermis with little impact on fat layers; ONDA, on the other hand, addresses both fat reduction and skin tightening.
• Three different tips available: Deep (for deep fat), Shallow (for shallow fat plus dermal firming), and Superficial (for cellulite and surface issues). You can switch tips depending on whether you’re treating your face or body.
Who it’s suitable for: People with a BMI of 18–30 who have stubborn localized fat along with sagging skin (Double Chin, sides of the waist, saddle area, arms, Thighs). Not suitable for: Those with extensive obesity; it’s recommended to lose weight first or consider liposuction. For those with only sagging skin without fat, a pure lifting procedure would be more appropriate.
II. The 3 clinics I visited in person – what makes each one stand out
RE:BERRY Reberry (Gangnam/Myeongdong/Incheon Airport)
I consider it the top choice among “body sculpting” treatments. What really sets it apart is that it uses DEKA Onda Premium-certified equipment (less than 50 clinics in all of Korea have this certification), meaning the machines, probes, and consumables are all supplied directly from the manufacturer. This is extremely important for someone like me who is worried about using refurbished probes. The treatment is performed personally by Director Dr. Yoon-Gon Ryu, who follows a “one patient, one doctor” policy—no changes in doctors from consultation to follow-up visits. The transparent pricing is what makes me feel most at ease—no surprise exorbitant fees once I arrive at the clinic.
It has three branches: Gangnam (the flagship store, open 365 days a year), Myeongdong (perfect for those shopping there), and Incheon Airport (with airport shuttle service, extremely convenient for transit passengers). It offers post-treatment follow-up via Chinese LINE for up to 3 months, making it very user-friendly for tourists from Taiwan and Hong Kong. If you’re considering a treatment on a larger area of your body, I’d recommend starting with this clinic first.

DIORE (Gangnam)
If you’re looking to improve your “face” – such as a Double Chin, loose jawline, or sagging flesh around the corners of your mouth – I’d recommend DIORE. Their ONDA treatment focuses on facial lifting and is performed personally by Dr. Lee Gwang-ryeol, the clinic’s lead physician. Pain sensitivity is a major concern for me, and DIORE’s probe comes equipped with built-in cooling technology. This keeps the skin surface cool while warming the deeper layers beneath, resulting in almost no pain at all – no anesthesia needed. There’s no redness or swelling right after the treatment, so you can head straight to Gangnam-daero to enjoy some barbecue.
What sets this clinic apart is its commitment to avoiding the “factory-style robotic treatment” approach. The director dynamically switches between 7mm and 3mm probes based on the distribution of your facial soft tissues, steering clear of areas prone to indentation such as below the cheekbones, while focusing on the lower jawline and Marionette Line Correction. For those who are sensitive to pain or have sagging cheeks, DIORE is definitely a clinic I would recommend.

Brandnew Clinic (Cheongdam-dong)
If you’re looking to achieve a more “systematic” body transformation, Brandnew is one of the earliest clinics in South Korea to introduce Body Onda. It breaks down the body into specific areas: upper arms, abdomen and waist, Thighs/Under Buttock Fold, and areas above the knees. Since fat thickness and sagging vary from one area to another, the treatment plan adjusts energy levels and session counts accordingly—rather than using just one machine to treat the entire body. The clinic’s director performs the procedure and advises patients to avoid heat exposure for 3 days after treatment (such as saunas or hot baths) and to drink plenty of water to boost metabolism.
Prices are determined based on the treatment area and number of sessions during a in-person consultation, and they’re not fully listed on the official website like at RE:BERRY. However, the categorized options make it easier for those who want to treat multiple areas on their body. The location in Cheongdam-dong is convenient for people living in that area.

VI. 8 Key Things I Always Check Before Choosing an ONDA Clinic
Focus Point 1｜Is the equipment original DEKA?
Certified clinics such as DEKA Onda Premium are given priority, with probes and consumables supplied directly from the manufacturer to ensure you avoid refurbished or unapproved equipment, thus guaranteeing both safety and optimal results.
Focus Point 2｜Is the practitioner a doctor or a skilled technician?
The ONDA energy level needs to be adjusted according to different fat thickness levels. There’s a significant difference between treatments performed personally by the clinic director/doctor and those done by nursing staff. All three clinics claim that doctors handle the procedures themselves, and I’ll verify this in person during my consultation.
Focus Point 3｜Whether the price includes tax and probe consumables
In South Korea, medical beauty quotes are usually given “excluding tax,” with an additional 10% VAT charged on site. Make sure to clarify whether the price includes probes and whether payment is due in full upfront—don’t let a low initial price trick you into facing extra charges when you get there.
Focus Point 4｜Is Chinese-language consultation and post-operative follow-up available?
This is extremely important for tourists from Taiwan and Hong Kong. RE:BERRY offers 3 months of post-treatment follow-up via Chinese-language LINE; other clinics also provide a Chinese-speaking support service before booking, ensuring coverage once you return home.
Focus Point 5｜Are the facial/body handles separate?
The Deep/Shallow/Superficial three heads are designed for different depths, with separate probes for the face and body. If a clinic uses just one head for the entire body, be cautious—there’s a risk it wasn’t adjusted according to specific body areas.
Focus Point 6 | Recovery Period and Post-Procedure Restrictions
ONDA requires no recovery time, but avoid heat exposure (such as saunas and hot baths) for 3 days after the procedure. Drink plenty of water to boost metabolism, with results gradually becoming apparent over 2–3 months—don’t give up just because you don’t see effects right away.
Focus Point 7｜Are the Indications Correct?
For those with a BMI over 30 and extensive obesity, ONDA isn’t the top choice; targeting localized fat along with sagging skin is the most effective solution. Be honest about your own condition first and don’t let anyone push you into treatments that aren’t suitable for you.
Focus Point 8｜Are There Real Reviews?
Go to Google and Naver to check out real reviews and case studies. Focus on feedback from after the procedure has been done for some time, rather than just immediate positive comments. All three platforms have a certain number of reviews, so take ten minutes to browse them before making a decision.
