After consulting with three different Gangnam clinics, I finally decided to undergo the Thermage FLX treatment at VelyB. It turns out that there are such significant differences between the fourth and third generations of this technology.

In Gangnam, there are so many Dermatology clinics that they are as common as convenience stores. However, finding one that does not force customers to follow a standard treatment plan and where doctors adjust the treatment parameters according to an individual’s specific situation really depends on luck. I stayed in Seoul for some time and visited four different clinics for Thermage consultations. In the end, I chose the VelyB Dermatology Clinic at Gangnam Station to undergo the fourth-generation FLX treatment. The reason was that they were one of the few clinics in South Korea that truly practiced the principle of “individualized treatment for each patient.” Moreover, their prices were transparent, and no additional treatments were added midway through the process. This article describes my actual experience during the treatment and also provides the latest information on the Thermage FLX treatment at VelyB Dermatology Clinic at Gangnam Station in 2026.

My first impression upon entering the VelyB Gangnam store: it doesn’t look like a clinic at all, but more like a studio.

VelyB Dermatology currently has over 40 branches in South Korea, making it a rather large-scale chain brand in the local market. The Gangnam branch is located on the 3rd floor of Hansung Building, at No. 423 Gangnam-daero, Seocho-gu, Seoul. It is only a 3-minute walk from Exit 4 of the Gangnam subway station, so the location is extremely convenient.

The feeling upon entering the door is quite different from that of traditional clinics. The overall decoration features a bright and minimalist style; the lobby is adorned with artistic paintings, the sofas are soft and comfortable, and there is drinking water available in the waiting area. What surprised me particularly was the emphasis on privacy protection – each customer is assigned an individual consultation room, so there is no awkward situation where several people have to discuss skin issues in the same space.

At the front desk, there is a staff member who can communicate in basic Chinese. The overall language services available include Korean, Chinese, English, Japanese, and Thai, making this institution particularly friendly towards foreigners. The clinic is closed on Sundays and public holidays, but it is open until 9 p.m. on Mondays, Wednesdays, and Fridays, which is quite convenient for working professionals.

What exactly are the improvements in the fourth generation of Thermage FLX? Director VelyB Kim Hye-rin explains it this way.

In 2022, Kim Hye-rim, on behalf of the director of the institute, led the brand to win the grand prize in the Dermatology category of the “South Korea Consumer Satisfaction Award.” The medical team she led all graduated from legitimate medical universities in South Korea, and many of them are members of academic organizations such as the Skin Anti-Aging Medical Association.

Regarding Thermage FLX, President Jin particularly emphasized three key aspects of the fourth-generation improvements during the consultation:

• Increased area and reduced time: The area of the probe has been increased from 3.0 cm² to 4.0 cm², and the number of laser pulses applied to the face has been reduced from 900 to 600, resulting in an overall reduction of treatment time by approximately 25%.
• Intelligent safety: The patented AccuREP™ algorithm automatically detects the skin impedance value before each emission and dynamically adjusts the output parameters, significantly reducing the risk of burns.
• The level of pain is significantly reduced: The 3D comprehensive circular vibration mode, combined with the full-course cooling system, allows Director Jin to claim that “the pain is reduced by more than 50%.” For someone like me who is particularly sensitive to pain, this is a crucial factor that makes this treatment highly attractive.

In terms of clinical data, official information from VelyB indicates that the skin elasticity index increases by more than 38% after the procedure, while the depth of the Nasolabial Fold Correction is reduced by over 42%. Additionally, 3 to 6 months after the surgery, the body enters a peak period for collagen regeneration.

It is recommended to request a detailed written statement of all costs before the procedure, including the costs of consumables and anesthesia, in order to avoid any disputes afterwards.

Complete record of the Thermage FLX treatment on that day: How long did it take from entering the clinic until the treatment was completed?

My actual process is roughly as follows:

1. Skin examination (about 10 minutes): The device analyzes various aspects such as the degree of skin aging, collagen density, and oil distribution. Based on the results, the clinic director customizes an energy treatment plan for each patient.
2. Cleanse and remove makeup (about 5 minutes): The clinic provides makeup removers to thoroughly cleanse the facial oils.
3. Applying anesthetic (about 30 minutes): Apply the anesthetic evenly across the entire face and wait for 30 minutes for it to take effect.
4. Energy test (5 minutes): The director first tested two or three areas in the lower jaw region to determine my skin’s tolerance level; for sensitive skin, the energy level was adjusted from 3.5 to 2.8.
5. Formal treatment (approximately 45 minutes): 600 hairs will be applied to the entire face. During the procedure, the director will continuously check on the patient’s comfort and make any adjustments necessary if any discomfort is experienced.
6. Postoperative sedation (about 15 minutes): Medical ice compresses + restorative facial masks; the nursing staff are very gentle in their approach.

The entire procedure took approximately 2 to 2.5 hours, which was shorter than I expected. The discomfort during the procedure was indeed much less intense than with the third-generation technology; it mainly consisted of a warm sensation and mild stinging sensations, all of which were completely within an acceptable range. After the surgery, my face turned slightly red, but this redness subsided after about 1 hour.

Is the VelyB Gangnam store suitable for me? Here are some honest thoughts for those who are considering going there.

The following are the criteria I have compiled based on my own medical treatment experiences and reviews from other users:

✅ Recommended target groups for participation

• Between the ages of 25 and 40, the face begins to show signs of relaxation, but it has not yet reached the point where surgery is necessary.
• Sensitive to pain, but still seeking noticeable results (the FLX fourth-generation vibration + cooling system provides greater comfort)
• People with language barriers (the institution provides basic Chinese services)
• It is hoped that results can be seen after just one treatment session, thus reducing the need for multiple visits to the clinic.
• It is necessary to combine multiple treatment sessions (the hospital offers packages that combine Thermage and HIFU).

⚠️ Groups that require special attention

• People with very limited budgets and who are sensitive to prices (the hospital targets the mid-to-high-end market segment).
• People who have no desire at all to be approached regarding any additional services or products (especially since some medical institutions tend to be more aggressive in promoting such offerings during certain periods).
• Those who expect immediate results and perfection right after the procedure (it takes 3 to 6 months for Thermage to reach its peak effect in collagen regeneration)
• Those who need to schedule a consultation on Sunday (VelyB is closed on Sundays and public holidays throughout Korea).
