Hello, this is 이지함피부과 Gangnam Branch.
Today, I would like to share a concern that we frequently encounter in the consultation room. Have you ever had an experience like this? You have not actually lost weight, but your cheeks seem to be sagging, and when you smile, your skin does not feel as firm and lifted as it used to. Have you ever looked in the mirror while washing your face in the morning and found your reflection strangely unfamiliar, staring at it for a long time?
I have met many patients who visit us after experiencing moments like these. Today, through the story of one of them, I would like to calmly explain Thermage in Seocho-dong, or Thermage FLX. I hope this article will be of some help in organizing your thoughts and concerns.

In Your Mid-40s, When It Feels Like Your Skin Betrayed You First
A few months ago, a patient in her mid-40s cautiously opened the door to the consultation room and came in. There was a slight sense of bewilderment in her expression. “Doctor, it is not that I am particularly unwell. It is just that my face seems to have sagged so much lately. My husband says I look tired these days, but honestly, I wonder if I am not tired and have simply aged.” I cannot express how deeply I empathized with her as I listened to those words.
She already knew that the issue was not fatigue, but gravity. When I examined her face, both cheeks had descended, and the area around the nasolabial folds had become deeper. The feeling of tension below the outer corners of her eyes had also decreased, leaving her overall facial contours less defined. Although she had not yet reached her 50s, it appeared that something that had been supporting her skin from within was gradually diminishing.
In fact, these changes do not appear suddenly at one particular moment. Changes that take place deep within the skin over a long period of time become noticeable all at once one day when you look in the mirror.

What Kind of Treatment Is Thermage FLX?
Thermage FLX is a lifting treatment that delivers radiofrequency (RF) energy to the deeper layers of the skin, inducing collagen contraction and regeneration. Put simply, you can think of it as delivering “warmth” into the skin to tighten the loosened structures within it. When we are young, collagen and elastin are densely arranged in the dermal layer of the skin, keeping it firm and resilient.
As we age, however, these structures gradually loosen, and gravity causes the skin to begin sagging downward. Thermage FLX delivers energy and thermal stimulation to the dermal layer and the SMAS layer beneath it—the superficial musculoaponeurotic system layer. During this process, existing collagen contracts while the production of new collagen is simultaneously stimulated. The principle is similar to smoothing out a wrinkled sweater with a steam iron: it reorganizes the loosened structures inside the skin.
The Thermage CPT available at 이지함피부과 also uses the same radiofrequency lifting principle and is an equipment option that demonstrates notable results in skin tightening and collagen regeneration. Because Thermage FLX is non-incisional, it brings about changes from within without creating wounds on the skin’s surface. This is also why many people take an interest in it.

How Does Radiofrequency Energy Work Within the Skin?
To explain in a little more detail, the radiofrequency energy delivered by Thermage FLX works by cooling the skin’s surface while selectively heating only the interior. When this heat reaches the dermal layer, the existing collagen fibers contract immediately, producing the first tightening effect. The process of forming new collagen then continues over several weeks to several months, which is why gradual changes may be felt after the treatment.
Some degree of improvement may be visible immediately after the treatment, but the main effects appear between 4 and 12 weeks, and many people experience the most complete improvement after 2 to 3 months. Results vary from person to person because skin thickness, degree of sagging, age, and skin condition differ for each patient.
The effects generally last for approximately 6 months to 1 year, depending on lifestyle habits and the condition of your skin care routine. In particular, sun protection and sufficient moisturizing after the treatment can help maintain the results.

Please Follow These Aftercare Instructions
Aftercare following Thermage treatment is just as important as the treatment itself when it comes to maintaining the results. After receiving Thermage treatment in Seocho-dong, it is recommended that you follow a few precautions. For one week after the treatment, please avoid activities that expose your skin to intense heat, such as saunas, Korean-style heated rooms, and strenuous exercise. Apply an SPF 50+ sunscreen thoroughly, and be sure to moisturize sufficiently after going outdoors.
Drink enough water and maintain regular sleeping habits, as these can also help with skin recovery. Since collagen regeneration takes place gradually, we recommend waiting patiently for 2 to 3 months rather than judging the results too soon. To maintain the effects, continuing treatment generally at intervals of 6 months to 1 year can be helpful.

A Relationship You Can Trust for the Long Term—That Is What 이지함 Strives For
At 이지함피부과, we believe dermatological care is not simply treatment, but a process of completing your beauty together with you. Every person’s skin is different, and even when people visit us with the same concern, the right solution may differ for each individual. That is why we do not simply recommend a procedure. Instead, we first aim to accurately assess each person’s skin condition and provide an appropriate diagnosis and direction.
If you are interested in Thermage in Seocho-dong, we hope you make a choice you can trust for a long time while pursuing a natural look without going too far. Rather than a single treatment, consistent skin care habits and honest medical care will continue to make a difference for longer. To become the name you think of first when skin concerns arise, 이지함 will continue to provide honest and dedicated care without change.
