What is the Thermage 900? Basic introduction
When you stand in front of the mirror and notice that the lines on your face are no longer as firm as before, that the contours of your chin have begun to fade, and that there is some slight excess fat around your mouth corners – at this point, many people start considering undergoing Thermage FLX treatment.
Thermage is a monopolar radiofrequency skin-tightening technology developed by the American company Solta Medical. It works by deeply heating the dermis to approximately 65°C, which stimulates the contraction and regeneration of Collagen, thereby achieving a tightening and lifting effect. The latest generation of Thermage FLX utilizes the AccuREP™ intelligent energy control technology, which automatically adjusts the output energy according to the skin impedance of different areas, resulting in more precise treatment and a significantly improved level of comfort during the procedure.
Among the numerous treatment parameters, “number of pulses” is one of the issues that people care most about. The so-called “number of pulses” refers to the frequency at which radiofrequency energy pulses are emitted. The standard configuration of the probe for the fifth-generation Thermage FLX is 900 pulses (for facial use), while the fourth-generation CPT uses 1200 pulses. This also explains why many people ask: “Is 900 pulses enough for South Korea’s Thermage treatment?”
There is no standard answer to this question, as it depends on several factors: the degree of skin laxity, the area to be treated, and the doctor’s approach to distributing the energy used during the treatment. In this article, we will analyze this issue from various perspectives: Is 900 treatments really sufficient? What are the price differences between Thermage 900 treatments in Gangnam, Seoul, and Busan? Which clinics are worth recommending? Let’s take a closer look together.
Price and market analysis of Thermage 900 in Gangnam, Seoul
Gangnam District in Seoul is the core area for medical beauty tourism in South Korea.

The specific cost may vary depending on the clinic brand, the doctor’s expertise, and whether additional treatments are included in the package.
Clinics in Gangnam District generally use genuine Thermage FLX devices and provide new probes that are customized for each individual patient. This is a very important guarantee for consumers.

In the treatment provided by Thermage 900, Toxnfill’s advantage lies in its transparent pricing and high cost-performance ratio.

PPEUM Dermatology is a chain of medical beauty clinics highly recommended by local South Koreans, with branches located in areas such as Gangnam, Hongdae, and Myeongdong. The Gangnam branch is situated beside the busy main roads of Gangnam, offering convenient transportation. It is common to see many local South Korean customers inside the clinic, which is also a testament to its quality.
In the treatment using the Thermage 900 device, what sets PPEUM apart is that doctors adjust the energy intensity according to your age and skin condition – not everyone uses the same parameters. For people aged 30–40 with mild to moderate skin laxity, 900 treatments are usually sufficient; however, for those over 45 years old with more pronounced skin sagging, doctors may recommend increasing the number of treatments to 1200 or combining them with Ultherapy HIFU.

The clinic provides detailed pre-treatment consultations, and doctors will explain the procedure in English or basic Chinese before the treatment, so that you can feel confident about the process.
Price and market analysis of Thermage 900 in Busan
Busan is South Korea’s second-largest city and also a popular destination for many tourists interested in medical aesthetics treatments. The cost of Thermage 900 treatments in Busan is generally 10-20% lower than in Seoul’s Gangnam district, which is one of the main reasons why so many people choose to undergo such procedures in Busan. According to market trends in 2026, the approximate reference prices for Thermage FLX 900 treatments in areas such as Seomyeon and Haeundae in Busan ranged from ₩1,200,000 to ₩2,200,000.
The advantages of the Busan clinic lie not only in its prices but also in shorter waiting times and more thorough communication with doctors. Unlike clinics in Gangnam District, where one doctor often has to see multiple patients at the same time, the pace at the Busan clinic is usually slower, giving doctors more time to carefully assess your condition.

Gangnam vs Busan: Price comparison of ReMaje 900
To help you more easily compare the differences in Thermage 900 treatments between Seoul’s Gangnam area and Busan, I have prepared a comparison table.

My recommendation: Is 900 enough? Should I choose 600, 900, or 1200?
This is a question for which there is no standard answer, but I can offer some suggestions depending on the specific circumstances. Below is the reasoning process I have developed based on years of observation and customer feedback:
Under what circumstances is 900 sufficient?
For people aged 30 to 40 with mild to moderate skin relaxation, 900 treatments are usually sufficient. At this age range, the skin condition is relatively good, and there is still a certain amount of Collagen present. The energy delivered by 900 treatments can effectively stimulate Collagen regeneration, resulting in noticeable tightening and Lifting effects.
If you fall into this category, I would recommend the Thermage FLX 900 for the face. The price is relatively affordable, and the results are quite satisfactory. Many customers have reported that 3 to 6 months after the treatment, their facial contours have become clearer, their jawlines more defined, and their overall appearance appears younger.
Under what circumstances should one consider using 1200 units?
For people over 45 years old who have significantly sagging skin and a thicker fat layer, 900 treatments may not be sufficient. At this age, the skin has undergone more extensive aging, so more intense stimulation is required to achieve noticeable results. 1200 treatments (usually using fourth-generation CPT probes) can provide more comprehensive coverage of all areas of the face, resulting in more significant outcomes.
It should be noted, however, that the pain experienced with 1200 treatments is more intense than that with 900 treatments, and the treatment duration is also longer. If you are particularly sensitive to pain, you may consider opting for a cooling and comfort system, or you can compare the differences between FLX and CPT before making a decision.
In what situations would 600 units be sufficient?
For people aged 25 to 35 with slightly loose skin who are looking for preventive anti-aging measures, 600 treatments (the lower dosage setting of the fifth-generation FLX) may be sufficient. For this age group, skin issues are not particularly severe, so 600 treatments can provide effective prevention and mild improvement.
However, it’s important to note that the results of using 600 doses may not be as noticeable as those achieved with 900 doses. If you want to see more significant improvements, I still recommend choosing 900 doses.
My personal recommendation
Overall, the 900-shot option is the best choice for the majority of people. It achieves a perfect balance between effectiveness, price, and discomfort level. 60% of customers who choose the 900-shot treatment are satisfied with the results, while only a small number of individuals with more severe skin conditions may need to increase the number of shots to 1200.
If you’re still unsure about how many implants to choose, my suggestion is to consult a doctor before the procedure and let them assess the condition of your skin before making a decision. A good doctor will provide the most appropriate advice based on your actual situation, rather than simply recommending the highest number of implants.
Frequently Asked Questions
Below are the 6 most frequently asked questions regarding South Korea’s Thermage 900 device, in the hope of helping to clarify any doubts you may have.
Q1: How long does the effect of the Thermage 900 treatment last?
A: Based on clinical data and customer feedback, the effects of Thermage FLX typically last for 12 to 18 months. The regeneration of Collagen is a continuous process, and the results are optimal 3 to 6 months after the treatment, after which they gradually diminish. To maintain these effects in the long term, it is recommended to undergo maintenance treatments every 1 to 1.5 years.
Q2: Will getting 900 injections be very painful? Are there any ways to reduce the discomfort?
A: The level of pain varies from person to person. Generally, the pain associated with 900 treatments is milder than that of 1200 treatments, but there is still a noticeable stinging sensation. Some ways to reduce pain include: ① Choosing a clinic that uses a cooling and comfortable system during the procedure; ② Taking painkillers 1 hour before the treatment (only with your doctor’s permission); ③ Communicating with your doctor about the intensity of the energy used during the treatment – and avoiding excessive high levels of energy.
Q3: How can I confirm that the Thermage FLX equipment used by the clinic is genuine?
A: There are several ways to do this: ① Request that the clinic provide anti-counterfeiting labels for the equipment and probes; ② Verify that the probes are brand-new, unopened, and assigned to a specific individual; ③ Choose clinics that have obtained BeautsGO certification, as these clinics have undergone quality audits by the platform.
Q4: How long does it take to recover after a Thermage treatment? Are there any side effects?
A: BARUNGYN is a non-invasive treatment, and there is basically no recovery period after the procedure. In some rare cases, patients may experience mild redness or sensitivity, which usually subsides within 1 to 3 days. Severe side effects are very uncommon; however, improper treatment may carry the risk of burns or uneven skin surfaces. Therefore, it is extremely important to choose an experienced doctor for this procedure.
Q5: Is it cheaper to undergo Thermage treatment in South Korea than in Taiwan or China?
A: Yes, the price of Thermage treatments in South Korea is usually 30-50% cheaper than in Taiwan and China. This is also one of the reasons why more and more people are choosing “medical tourism” – they can combine traveling with medical treatments, resulting in lower overall costs. For a detailed comparison of prices, you can refer to this article.
Q6: If I’m not satisfied with the results after 900 treatments, can I get more sessions?
A: Technically, it is possible, but it is not recommended to administer too many treatments within the same session, as the skin needs time to heal and regenerate collagen. If you are still dissatisfied with the results after 6 months, you can consider undergoing a second treatment or combining it with Ultherapy HIFU for more significant effects.
