Dr. Bang Chan-il, Director of Human Dermatology Seoul National University Branch
Hello,
This is Human Dermatology Seoul National University Branch.
Some people feel that their face looks flatter than before when they take photographs, or that their skin looks tired even after getting enough rest. These changes are not necessarily caused simply by increased facial fat or sagging contours. When the elastic structures supporting the skin gradually loosen, light is not reflected evenly from the skin’s surface. As a result, the skin texture may look rough, and the overall impression of the face may appear less vibrant.
Therefore, when looking into lifting procedures, it is a good idea to consider not only how strongly the facial contours can be lifted, but also how the firmness of the skin itself will be managed. Among those looking for a Thermage FLX dermatology clinic near Sadang Station, many want their skin to look smoother and healthier while maintaining their natural appearance, rather than undergoing an excessive transformation. Based on these concerns, Thermage FLX is a procedure that may help improve the foundation of the skin’s elasticity.
Before Choosing a Thermage FLX Dermatology Clinic near Sadang Station
Points to Check

Thermage FLX is a lifting procedure
that improves skin firmness
Thermage FLX is a nonsurgical lifting procedure that delivers radiofrequency energy to the skin and induces a thermal response within it. Rather than making an incision in the skin’s surface or directly pulling the tissue, it delivers energy to layers associated with the skin’s elasticity to help improve the firmness of loosened skin. Depending on the condition of the skin, it may help improve the appearance of looseness in the cheeks or jawline and fine lines around the eyes and mouth.
During the procedure, the radiofrequency energy is delivered evenly to the required depth while protecting the skin’s surface. Accordingly, it may be considered by people who prefer natural-looking changes or want to manage skin firmness without placing a significant burden on their daily lives. At a Thermage FLX dermatology clinic near Sadang Station, it is important not to approach the procedure simply as a way to pull the face strongly. Instead, the treatment plan should be established after assessing the skin’s elasticity and the direction of sagging, focusing on the areas that require it.

We assess not only the facial contours
but also the skin’s “density”
A decline in skin elasticity does not only cause the jawline to become less defined. The cheeks may feel softer and looser than before when touched, and fine lines may settle more easily around the eyes and mouth. Skin that feels less smooth and appears thinner can also be a change associated with reduced support beneath the skin. Therefore, lifting should not focus solely on the contours; it is also necessary to assess how dense and firm the skin feels.

Thermage FLX delivers thermal stimulation to the collagen environment beneath the skin and may help manage both skin texture and elasticity. Because its approach differs from procedures that add volume to the skin, it may offer natural-looking changes in which the skin appears more refined and denser, rather than producing excessive volume changes. During a consultation at a Thermage FLX dermatology clinic near Sadang Station, factors such as skin thickness and dryness, the location of fine lines, and the skin’s firmness when pressed by hand are carefully assessed to determine the appropriate care needed for the current condition of the skin.

A procedure suited to your face is important
Because facial shape and skin condition vary from person to person, using the same number of shots does not produce identical results. The areas that appear to have lost elasticity may differ between a face with prominent cheekbones and one with a broad lower jaw. The appropriate energy range may also differ between people with thin, sensitive skin and those with thicker, firmer skin. A natural treatment plan can be established only by considering the facial bone structure, fat distribution, and direction of skin sagging together.

In particular, delicate areas with thin skin, such as around the eyes and mouth, require a careful approach. In relatively thicker areas, such as the cheeks and jawline, the energy must be adjusted according to the condition of each area. At a Thermage FLX dermatology clinic near Sadang Station, importance is placed not only on the number of shots itself, but also on determining which areas should receive concentrated energy and which areas should be treated more delicately. A precise procedure tailored to each person’s areas of concern is necessary to maintain the strengths of the face while achieving natural-looking changes in firmness without an overly burdensome appearance.

Changes appear gradually
according to the skin’s regeneration process
After a Thermage FLX procedure, you may feel that your skin has become somewhat firmer due to the thermal response. However, the changes visible immediately after the procedure are not the final result. After the radiofrequency energy is delivered, collagen beneath the skin continues to undergo a process of reorganization and regeneration. Accordingly, changes in skin texture and elasticity may gradually appear over a certain period.
The timing at which changes appear and the length of time they last may vary depending on skin thickness, the degree of aging, lifestyle habits, and each person’s regenerative response. At a Thermage FLX dermatology clinic near Sadang Station, we recommend keeping the skin sufficiently moisturized so that it does not become excessively dry after the procedure and applying sunscreen carefully. It is advisable to temporarily avoid activities that may burden the skin, such as saunas involving intense heat or excessive alcohol consumption, and to care for the skin so that it can recover comfortably.


Thermage FLX is a lifting procedure chosen by many people, but it cannot be applied in the same way to every type of skin. If excessive energy is delivered to a face with thin skin and little subcutaneous fat, or if the procedure is performed without sufficiently identifying the cause of reduced elasticity, you may experience changes that differ from what you wanted. Conversely, selecting an intensity and treatment area suited to the current skin condition may help manage elasticity naturally without compromising the original impression of the face.

At our clinic, a board-certified dermatologist directly assesses skin thickness and sensitivity, facial bone structure, fat distribution, and the location of wrinkles and sagging before the procedure. If you are looking into a Thermage FLX dermatology clinic near Sadang Station, it is important to look beyond simply comparing the equipment or number of shots and check whether an accurate diagnosis by a board-certified dermatologist and a customized procedure are provided. You should proceed only after a sufficient consultation has given you an understanding of the changes that can reasonably be expected and how to care for your skin after the procedure. This can help you continue with more comfortable and satisfactory elasticity care.
