Thermage FLX is one of the radiofrequency treatments that has been available on the global non-surgical lifting market for the longest time and has received the most extensive discussion. In South Korea, a full-face treatment with 900 sessions of the 5th-generation FLX procedure costs approximately 900,000 South Korean won. Compared to similar treatments in Taiwan, the price difference is quite significant. This article provides an overview of the treatment details for Thermage FLX, the suitable candidates for the 900-session package, and important precautions to take when undergoing this treatment in South Korea.
What are the differences between Thermage Generation 5 (FLX) and its previous versions?
Thermage FLX is the fourth-generation upgraded model, which is what the market refers to as the “fifth generation.” Compared to the fourth generation, FLX features three main improvements: an upgraded probe (AccuREP technology, ensuring more consistent energy delivery per pulse), a new vibration mode that reduces discomfort, and a significantly shorter treatment time (much faster than the third generation).
Currently, FLX is the most commonly used product on the market. If a clinic is still using the older third-generation version, the efficiency and comfort of the treatment will be significantly lower. Remember to check which version of the equipment is being used at the clinic before making an appointment.
What exactly does “900 shots” mean?
The “number of treatments” referred to in Thermage means the number of times radiofrequency energy is applied. More treatments are not necessarily better; instead, the number should be appropriate for the specific area being treated. Generally, a basic full-face treatment involves 300 to 600 sessions, while 900 sessions constitute an enhanced full-face treatment option, suitable for:
For those with larger facial areas, moderate to significant skin laxity, or who wish to treat the areas around the eyes and neck simultaneously. Some clinics offer 900-shot packages that include treatments for the eye area (to reduce fine lines around the eyelids) or the neck, providing a more comprehensive anti-aging effect. The specific areas covered may vary depending on the clinic’s treatment plan, so it’s important to clarify these details during a personal consultation.

The working principle of Thermage
Thermage is a Monopolar RF treatment. The energy generated by this technique can penetrate deep into the dermis and the SMAS fascia, heating the Collagen and causing it to contract immediately. At the same time, this process triggers the subsequent regeneration of Collagen. As a result, patients experience a slight tightening effect on the day of the treatment, and the effects continue to improve over the following 2 to 3 months, reaching their peak at that time.
Compared with HIFU ultrasound, Thermage has a more even effect and is better at improving skin quality, reducing fine lines, and enhancing overall skin tone. Its physical effect on shaping the contours is relatively weaker; HIFU ultrasound, on the other hand, is more effective in creating a “lifting” effect. Many people use both techniques together: first using HIFU ultrasound to shape the contours and then applying Thermage to nourish the skin.
What is the difference between getting injections in South Korea and in Taiwan?
For the same standard Thermage FLX treatment, the cost in South Korea can be 3 to 5 times higher than that in Taiwan. The main reason for this difference is…
Firstly, the medical beauty market in South Korea is highly competitive, with a large number of clinics competing with each other, resulting in relatively low pricing. Secondly, the exchange rate of the Korean won has been favorable for Taiwanese tourists in recent years. Thirdly, some Korean clinics offer package discounts or additional services to tourists.
However, a low price does not necessarily mean poor quality. What is more important is to confirm whether the clinic uses genuine probes manufactured in the United States (not counterfeit products), whether the procedures are performed by doctors specializing in Dermatology or Plastic Surgery, and whether the probes are opened and verified on-site. These factors are far more crucial than the price and deserve prior attention.

How should I take care of my skin after the treatment?
BARUNGYN did not experience any injuries, and she could wash her face and go out as usual after the treatment. Her face might turn slightly red, but this usually subsides within a few hours to a day. Here are some things to keep in mind after the procedure:
In the first three days, it is important to enhance moisturization to help with the regeneration of Collagen. Sun protection is essential, as the skin becomes more sensitive to ultraviolet rays after the treatment. For at least one week, avoid using irritating skincare products such as those containing high concentrations of retinol or exfoliants. It is also recommended not to undergo any similar types of radiofrequency treatments within one month after the procedure to prevent excessive irritation.
Explanation of the fees for 900 treatments
In South Korea, getting 900 Thermage FLX treatments across the entire face costs approximately 900,000 South Korean won. The price may vary depending on the clinic and the specific areas treated. Converting 900,000 South Korean won into Taiwanese dollars, the cost is around 20,000 yuan (subject to exchange rates). This is significantly lower compared to the prices in the Taiwanese market, which typically range from 40,000 to 80,000 yuan per treatment.
When choosing a clinic, in addition to comparing prices, it is also recommended to verify the following aspects: whether the facility is equipped with FLX (5th-generation) technology, whether the probes used are genuine and original, the doctor’s licensing qualifications, and whether post-treatment instructions and follow-up care are included. Lower costs may sometimes indicate that the equipment or the operator is not of high quality; therefore, it is advisable to ask more questions during the in-person consultation.

Who is suitable for the Thermage 900 treatment?
In the following situations, it is more reasonable to choose the 900-shot full-face enhancement package: those with moderate facial sagging (drooping eye corners, prominent Nasolabial Fold Correction, blurred jawlines), those with larger facial areas, those who wish to treat their eye areas or neck at the same time, and those who have previously undergone basic treatment packages and want to improve the results.
If it is your first time trying Thermage, if the degree of relaxation desired is mild, or if your budget is limited, a treatment with 300 to 600 hairs is actually sufficient; there is no need to opt for the maximum number of hairs from the beginning. The specific recommendation should still be based on the results of a face-to-face consultation. Only after examining your skin condition can a doctor provide the most suitable treatment plan for you.
