How much does Onda treatment cost at Dermatology clinics in South Korea? I visited 4 clinics in Seoul before finally getting clear on the actual price for 2026 and the things to watch out for.

When I went to Seoul this time, I originally planned to just get a hydrating treatment. But after my friend mentioned that “my chin line looks a bit loose,” it piqued my curiosity, and I added an Onda treatment to my schedule on the spot. Only after visiting four different Dermatology clinics did I realize that the prices for Onda ranged from 390,000 to 1,090,000 won. The difference didn’t lie in the reputation of the clinic, but rather in three factors: the number of sessions, the areas treated, and whether tightening treatments were included. In this article, I’ll share all the actual prices I asked about, how the clinics evaluated the treatments, and the things I think are worth paying attention to.

What exactly is Onda? Why are so many people in South Korea asking about it?

Onda (Onda Coolwaves) is an original microwave body sculpting device manufactured by Italy’s DEKA company, utilizing 2.45GHz microwave energy. In South Korea, Dermatology clinics often recommend it as an option for “non-invasive fat reduction and skin tightening.” Common treatment areas include the Double Chin, jawline, waist and abdomen, excess fat on the arms, outer Thighs, and it’s also used to address orange peel skin on the Buttocks.

I originally thought it was similar to Thermage. It wasn’t until the clinic director explained that I understood: Thermage focuses on “tightening the dermal layer,” while Onda “heats the fat layer, causing fat cells to enter apoptosis” and also promotes some collagen regeneration. As a result, for those with fat-filled cheeks or localized fat accumulation, the results are more noticeable than just simple tightening.

2026 Price Reference for Dermatology Onda in South Korea (Actual range I inquired about)

Here are the publicly available reference prices I asked about during my trip to Seoul. All amounts are in South Korean won and do not include a 10% tax surcharge. Each clinic uses a different pricing method—some charge by “area,” some by “energy (kJ),” and others by “number of shots.” So be sure to clarify the unit of measurement before checking the prices.

* Prices may vary depending on hospital promotions, exchange rates, and packages for foreigners. The information above is compiled from publicly available data as of August 2026; the actual price will be determined upon in-person consultation.

Pricing by energy is another set of calculations.

Besides pricing by treatment area, some clinics will directly quote you based on “energy usage.” The plan I saw at RE:BERRY in Gangnam was structured this way:

A quick reminder here: higher energy levels don’t necessarily mean better results. All the clinic directors I consulted said that people with thicker fat layers can use higher energy settings, but for those with thin skin or sagging skin, too high an energy level can actually cause swelling to last longer. So when comparing “40 kJ vs 100 kJ,” it’s not just about the CP value — individual factors such as fat thickness and skin elasticity also play a crucial role.

Reference prices for the 4 hospitals I inquired about (from lowest to highest)

Here are the 4 clinics I actually visited or for which I found public pricing information. Each has a different pricing logic, and comparing them side by side will make it clearer:

It’s also called Onda, but the price difference can be as much as two to three times. The key isn’t to go for the cheapest option—it’s important to ask clearly: “What level of energy does this price correspond to? Is post-treatment care included? Will it be performed by the director of the clinic?”

Second half: 5 Things I Really Care About When Choosing a Hospital

Focus Point 1｜Is the equipment original DEKA, and does it come with three types of probes?

The authentic Onda devices are produced by the Italian company DEKA. Some clinics in South Korea use other machines that claim to work on a similar microwave principle but actually deliver subpar results. I always ask the clinic director directly, “Is this an Onda Coolwaves?” and make sure it comes with three different tips: Deep for deep fat reduction, Shallow for surface tightening, and Body for larger treatment areas. At RE:BERRY, the director showed me the DEKA anti-counterfeiting code on the tip right away, which gave me much more confidence.

Focus Point 2｜How to calculate energy and treatment count – don’t just look at the price per session

When it comes to getting an “Onda treatment,” some clinics use 40 kJ while others use 100 kJ — naturally, the prices vary accordingly. I always ask them to clearly specify the energy level, treatment area, number of pulses, and duration of the procedure, then calculate the cost per kJ. This way, price comparisons are fair. THE BEAUTY provided me with a detailed breakdown showing 20 minutes per session at ₩500,000 — for someone like me who is on a tight schedule, this already takes the time cost into account.

Focus Point 3｜Treatment Area and Plan Design – Not Everyone Is a Good Candidate for the Same Approach

For areas like the Double Chin and jawline—smaller regions—results are usually noticeable after just 1 to 2 treatments. For larger areas such as the waist, abdomen, and Thighs, clinics generally recommend 3 to 5 sessions. I have fat accumulation around my jawline that causes a rounded appearance, and my doctor suggested starting with 2 sessions spaced 4 weeks apart, then deciding whether more treatments are needed. Never let the idea that “the more you buy, the cheaper it gets” influence your decision; first make sure you truly need that many sessions.

Focus Point 4｜Post-surgery care and recovery: Will swelling affect your plans?

Although Onda claims to have no recovery period, from my experience, most people still experience swelling for 2 to 7 days, especially in areas treated with higher energy levels. I always ask if the clinic offers post-surgery lymphatic drainage, LDM therapy, or Vacumed-assisted metabolism treatments. RE:BERRY includes Vacumed as part of its package, while THE BEAUTY allows clients to purchase LDM therapy separately—these are the details that determine whether it’s worth the price.

Focus Point 5｜Soft criteria such as Chinese language, Sundays, and tax refunds

I can barely speak Korean, so I make sure to check in advance whether there are Chinese-speaking consultants available or if BeautsGO can help with communication. THE BEAUTY is open until 21:00 on Fridays, which is very convenient for those arriving in Seoul in the afternoon; DIORE is located near Gangnam Station, making it easy to visit while shopping; RE:BERRY is open year-round, but it gets busier on weekends. Additionally, South Korea’s medical beauty tax refund policy will change in 2026—some clinics will now offer “the same price as in China” instead of refunds. Be sure to ask about the final price including taxes before checking out.

My honest opinion: These three types of people don’t need to rush into getting an Onda.

After visiting these clinics, I think Onda isn’t a one-size-fits-all solution. If you fall into any of the following three categories, it’s advisable to have an honest conversation with the clinic director first before spending money.

1. People with severely sagging skin and very little fat: Onda’s main advantage lies in heating the fat layer, but for those with extremely thin faces, its results may not be as good as Thermage or thread lifting.

2. Those hoping for quick results: Most people start to notice changes after 2–4 weeks, with a full treatment course typically requiring around 3 sessions—those in a hurry may end up disappointed.

3. Those who can’t tolerate post-surgery swelling: Although there are no wounds, the treated areas may swell for a few days. If you need to take photos or meet people the day after, it’s worth considering this factor.

Pro tips to save money

If you’re visiting South Korea for an Onda procedure for the first time, just like I am, you can plan it this way:

• First, identify 2–3 clinics and compare prices on BeautsGO—don’t wait until you’re there to look around last minute.

• Make sure to clarify “energy + treatment area + tax,” don’t just focus on the Korean won amount.

• Plan to stay in Seoul for 2–3 days after the procedure, so you can return for follow-up visits or corrective treatments if swelling occurs.

• Avoid using Onda and Thermage on the same area on the same day—both are thermal treatments that can easily cause excessive irritation.
