Understanding the Features of Thermage in Seocho-gu

Hello, this is the Gangnam branch of Lee Jiham Dermatology.

Have you ever stood in front of the mirror, gently lifted your cheeks, and paused in that position for a moment? Some of you may have a habit of doing the movement that used to pass by without a second thought. The moment you think, “When did my skin start to look like this?” many people begin looking for information about lifting procedures.

Today, for those people, I’d like to talk about Thermage FLX by sharing the story of a patient I actually met in the clinic. If you read this article to the end, I’m sure you’ll take away information that will be helpful for anyone considering Thermage in Seocho-gu.

What exactly is Thermage FLX?

Thermage FLX is a procedure that delivers radio frequency (RF) energy to the deeper layers of the skin to induce collagen regeneration and skin tightening. It is often called “radio frequency lifting.” To explain it more simply, the skin is made up of the outer epidermis, the dermis beneath it, and the SMAS layer (superficial musculoaponeurotic system).

As we age, collagen and elastin in the dermis decrease, causing the skin to sag and lose elasticity. Thermage FLX focuses thermal energy on the dermis and SMAS layer to contract collagen fibers and stimulate the production of new collagen. It may be easier to understand if you think of it as using proper heat to restore an overextended spring to a firmer state.

The FLX version, upgraded from the previous Thermage CPT, is a device with improved energy delivery uniformity and skin contact detection, allowing for more precise treatment. When searching for Thermage in Seocho-gu, many people confuse these two models, so it is important to check exactly which device is being used. Lee Jiham Dermatology has both Thermage CPT and Thermage FLX, and selects the appropriate device according to the patient’s skin condition.

Why Thermage FLX is especially effective

The people I usually recommend Thermage FLX for are those whose skin sagging has progressed overall but who still do not want a surgical option, those who hope for collagen regeneration along with skin tightening, and those who want to treat a relatively large area in a single session. One of the biggest features of Thermage FLX is that it delivers heat to the deep layers of the dermis while protecting the epidermis.

Because it induces collagen denaturation and regeneration inside the dermis without directly injuring the skin surface, returning to daily life after the procedure is relatively easy. Some redness or swelling may occur immediately after treatment, but in most cases it subsides within 1 to 3 days. Compared with ultrasound lifting (Doublo Gold, Vro, Shurink), Thermage FLX is more suitable for overall skin tightening because it delivers thermal energy uniformly over a broader area.

By contrast, ultrasound lifting delivers focused energy to a specific depth to directly stimulate the SMAS layer, so it can be effective when sagging is severe. The two methods are not mutually exclusive, and depending on the skin condition, they can be used together or in sequence. If you are considering Thermage in Seocho-gu, understanding these differences in treatment principles first will help you make the right choice.

What you do after Thermage FLX is important.

You may feel some immediate effect right after Thermage FLX, but the full changes appear over 4 to 12 weeks. This is because time is needed for new collagen to form and for the dermal structure to be reorganized. Many people experience the most noticeable changes after 2 to 3 months, and although results vary by individual, they generally last about 6 months to 1 year.

To extend this period as much as possible, daily care is important. For one week after the procedure, avoid saunas, jjimjilbangs, and strenuous exercise, and be sure to apply sunscreen with SPF 50 or higher carefully.

UV rays are one of the biggest external factors that accelerate skin aging, so you should block them thoroughly, especially during the period when the skin is sensitive after treatment. Drinking enough water and maintaining moisture also help create an environment for collagen regeneration.

Skin care is not just a single procedure.

At Lee Jiham Dermatology, we see dermatologic care not simply as treatment, but as a “process of completing your beauty.” Above all, what matters most is natural results without overdoing it and long-term trust. Rather than promising dramatic changes from a single procedure, we aim to provide diagnoses and solutions tailored to each person’s skin.

Every skin type is different, and even the same procedure should be applied and managed differently. Through honest medical care, proven procedures, and the hands of a specialist, we aim to become a clinic you can trust for a long time, not just for a single visit. In order to become the name that first comes to mind when skin concerns arise, we will continue to provide honest and safe care without change.

Did you gently lift your cheeks in the mirror again today?

To finish with one last thought: feeling that your skin elasticity is changing is an unfamiliar and unsettling experience for anyone. But it is a natural part of aging, and if managed at the right time with the right method, improvement is certainly possible.

For those who arrived at this article while searching for Thermage in Seocho-gu, I hope today’s post has been at least somewhat practical. What matters is not the procedure that others say is good, but first understanding what your skin needs right now. Like the patient who opened the clinic door and walked in, I hope you will take that first brave step. Lee Jiham Dermatology will be by your side on that journey.
