If you are someone considering undergoing cosmetic procedures in South Korea, you have probably heard of Thermage FLX. As the most popular non-surgical tightening device currently available worldwide, the fifth-generation Thermage FLX has become the most widely discussed anti-aging treatment on the Dcard cosmetic surgery platform, thanks to its ability to provide results that last for over a year with just one treatment.
However, when you start doing some research, you’ll encounter a confusing phenomenon: for the same Thermage FLX 900 full-face treatment, the prices in Gangnam District, Seoul, and Seomyeon, Busan, differ by nearly 30%! Is this price difference merely due to legitimate cost variations, or is there something else hidden behind it?
This article will start with real market data to conduct a detailed comparison of the actual prices offered for Thermage FLX 900 treatments in the Gangnam area of Seoul and the Busan region. It will also recommend 3 verified and legitimate Dermatology clinics in each area, providing you with clear recommendations for your final choice.

Overview of the market situation for South Korea’s Thermage FLX 900 device
What is Thermage FLX? Why should we pay attention to the number of treatments?
Thermage FLX (referred to as “Thermage” in Taiwan, “热玛吉” in Mainland China, and “써마지” in South Korea) is the fifth-generation radiofrequency skin tightening device developed by the American company Solta Medical. Its core principle involves using Monopolar RF energy to heat the Collagen located deep within the dermis, causing it to contract immediately and stimulating new collagen production. This process helps to tighten the skin and reduce the appearance of fine lines.
“The number of shots is one of the most critical parameters in Thermage treatment. Each ‘shot’ represents one release of radiofrequency energy by the probe, covering a treatment area of approximately 1 square centimeter. A standard configuration of 900 shots is suitable for the entire face (including the jawline) and part of the neck, and is ideal for individuals aged 30–45 with mild to moderate skin laxity. Too few shots will result in inconspicuous effects, while too many shots not only increase the cost but also place unnecessary strain on the skin.”

Seoul Gangnam District: Why is it so expensive?
Where does the “premium” in Gangnam District come from?
Gangnam District in Seoul is the heart of South Korea’s medical aesthetics industry, bringing together the country’s top Dermatology experts and the most advanced equipment. Walking along areas such as Gangnam Station and Apgujeong Rodaeo Street, one can almost see the signboards of medical aesthetics clinics every few steps. However, this high density has not led to lower prices; instead, it has created a unique ecosystem characterized by premium prices.
- High rental costs: The commercial rental rates in the core areas of Gangnam District, such as along Gangnam-daero and Nonhyeon-ro, are 2 to 3 times higher than those in Seomyeon of Busan. These high costs are directly reflected in the treatment prices.
- Brand premium of physicians: In many clinics in Gangnam District, the “famous chief physicians” themselves are in charge. These physicians possess extensive academic backgrounds or connections in the entertainment industry, and having their names associated with a clinic inherently confers brand value.
- High-end service experience: From one-on-one personalized consultation rooms and five-star waiting areas to post-operative care packages, Gangnam Clinic offers a comprehensive “luxury experience” rather than just simple treatment.
- Price policies for foreign customers: Some clinics have separate pricing systems for foreign clients (these prices may not necessarily be higher, but the range of choices is limited). It is recommended to check transparent prices through platforms like BeautsGO.

Busan Area: A New and High-CV Option in the Medical Aesthetics Industry
Why is Thermage in Busan so affordable?
As South Korea’s second-largest urban center, Busan has seen rapid development in the medical aesthetics industry in recent years. In particular, the Seomyeon area has emerged as a medical aesthetics hub on par with Myeongdong in Seoul. For the same original Thermage FLX equipment and genuine probes, the prices in Busan are approximately 30% lower than those in Gangnam. The logic behind this is actually quite simple.
- Lower rental costs: The commercial rental rates in the core business district of Seomyeon are only 40%-50% of those in equivalent locations in Gangnam. The resulting cost savings are directly reflected in the treatment fees.
- The business model based on volume-based pricing: Since Busan clinics rely more on word-of-mouth and foreign tourists, they tend to adopt a “high cost-performance ratio” approach to attract customers, rather than pursuing a high-end, premium strategy.
- Fierce competition has led to transparent pricing: Within a radius of 500 meters around the Seomyeon station, there are over 20 Dermatology clinics, resulting in highly transparent price information and giving customers ample room to compare prices.
- Same-price policy for Chinese and Koreans: In most regular clinics in Busan, the “same-price policy for Chinese and Koreans” is implemented for foreigners, and no additional charges are made just because someone is a tourist.

Final decision advice: Should you go to Gangnam or Busan?
After analyzing so many options, how should one make a choice? Our advice is very clear:
If you choose Gangnam in Seoul…
- Have sufficient budget (are willing to pay treatment costs of over ₩1.6 million) and seek the expertise of top physicians in South Korea.
- Having a strong preference for a particular director or clinic (for example, consistently paying attention to the reviews of pind or barog)
- The itinerary focuses mainly on Seoul; it is not convenient to make a special trip to Busan.
- There is a need for more comprehensive Chinese-language services and a one-stop medical beauty experience.
Choose Busan if you:
- My budget is limited, but I don’t want to compromise on quality. With the same original Thermage FLX device and original probes, you can save a direct 30% on the price.
- The itinerary already includes a stop in Busan (or you can take the KTX from Seoul for a dedicated trip, which takes approximately 2.5 hours).
- Prefers a less crowded treatment environment and hopes for more one-on-one consultation time.
- I plan to enjoy both the beautiful sea views and delicious local cuisine in Busan, turning this medical beauty trip into a perfect vacation.
💡 Our ultimate recommendations
If you only offer the Thermage FLX treatment, go straight for Busan! Using the same equipment, the same probes, and achieving the same results, ordering 900 treatments can save you between ₩300,000 and ₩700,000 (approximately NT$6,800 to NT$16,000). With this amount of money, you would still have enough left to cover the cost of KTX tickets and accommodation.
If you also wish to combine these treatments with other high-end procedures such as Filler injections, botulinum toxin injections, or skin management treatments, it is recommended that you stay at Gangnam. The treatment packages offered at Gangnam Clinic are more flexible, and the doctors there have greater experience in dealing with complex cases, allowing for a higher degree of customization in the overall treatment plan.
No matter which region you ultimately choose, the most important thing is to ensure that the Thermage FLX equipment used by the clinic is genuine, including the original manufacturer’s probes, and that brand-new probes are used for each treatment. In this regard, all certified clinics listed on the BeautsGO platform have passed equipment verification, so you can book appointments with confidence.

Frequently Asked Questions
Q1: What are the differences between South Korea’s Thermage FLX 900 and 600 models?
The 900-shot package covers the entire face, including the jawline, as well as a portion of the neck area, making it ideal for those experiencing moderate skin laxity. The 600-shot package is primarily designed for facial tightening and does not include the neck. It is generally recommended that individuals over the age of 30 who have noticeable blurring of their facial contours opt for the 900-shot package.
Q2: Will the Thermage treatments in Busan use fake probes just because they are cheaper?
This is something that requires special attention. However, as long as it is a regular clinic certified by BeautsGO (such as JRYN, Renovo, and Deforest recommended in this article), the Thermage FLX devices and probes used there have all been verified by the manufacturer. It is recommended to check the anti-counterfeiting label on the probe packaging before the treatment to ensure that the probe is brand-new and unopened.
Q3: Is it possible to travel from Seoul to Busan for medical beauty treatments and return back in one day?
Certainly. Taking the KTX from Seoul Station to Busan Station takes approximately 2 hours and 30 minutes. The treatment time for Thermage 900 is around 60–90 minutes, and including the consultation and post-treatment care, the whole process can be completed within half a day. It is recommended to schedule a morning appointment so that you can return to Seoul by train in the afternoon, or you could also take the opportunity to spend a day in Busan.
Q4: Is there a recovery period required after treatment with South Korea’s Thermage FLX?
Thermage FLX is a non-invasive treatment that requires almost no recovery time after the procedure. Mild redness or swelling may occur after the treatment, but these symptoms usually subside within a few hours, allowing you to apply makeup on the same day. It is recommended to enhance moisturization and sun protection in the week following the treatment, and to avoid high-temperature environments such as saunas or hot springs.
Q5: Can foreigners getting Thermage treatments in South Korea get a tax refund?
Sure! Medical beauty treatments in South Korea are considered medical services. Visitors holding foreign passports can claim a VAT refund at the airport after receiving treatment at legitimate medical institutions. The typical refund rate ranges from 5% to 7% of the total amount spent, although this may vary depending on the refund system used by each clinic.
Q6: Do clinics in both Gangnam and Busan accept credit card payments?
All the clinics recommended in this article accept international credit cards (Visa/Mastercard) as well as local payment methods in South Korea. Some clinics offer additional discounts for cash payments (ranging from approximately 5% to 10%), so it is recommended to inquire about these details during the consultation process.
Q7: If I don’t know Korean, will there be any difficulties in communicating regarding medical aesthetics treatments in Busan?
Some clinics in Busan, such as JRYN and Renovo, offer Chinese translation services, but these services are not as widely available as those in Gangnam. It is recommended to check the option “Require Chinese translation” when making a reservation through the BeautsGO platform, and the platform will arrange the corresponding service for you. Alternatively, you can add F394666 on WeChat for assistance in arranging these services.
