Thermage FLX
Hello, this is Jamsil On Dermatology :)
Last Monday, we shared a detailed introduction to our Jamsil On clinic. Starting today, we’ll be sharing a variety of content that can help support your skin health! Our first topic is Thermage FLX lifting. I think the most basic foundation of skin health is “dermal layer care.” Today, let’s take a closer look at why the dermal layer is so important and whether Thermage FLX can help manage dermal layer health :)

Thermage FLX
Why is the dermal layer important?
The skin is broadly divided into the epidermis, dermis, and subcutaneous tissue. Among these, the dermal layer plays the most essential role in skin structure! Looking more closely at the dermal layer, you can see that it is densely made up of collagen and elastin fibers, which are involved in maintaining the skin’s elasticity, density, and volume. As a result, when the dermal layer weakens due to various external stimuli or aging, the skin easily sags and loses elasticity.
When dermal damage accelerates, it also affects the epidermis! As a result, wrinkles become more noticeable and the skin texture can become rougher. Please keep in mind that visible signs of aging are not simply a problem on the skin’s surface, but rather stem from structural weakening in the dermal layer.

What happens when the dermal layer is damaged?
What kinds of skin problems can you experience when the dermal layer is damaged? You can think of various skin concerns appearing in a chain reaction. First, overall facial elasticity decreases, causing the skin to sag and making expression lines more likely to deepen. In addition, the skin may become drier and its protective function may weaken, making it more sensitive to external irritation.
Pore enlargement, rough skin texture, and loss of facial volume are also typical results of reduced dermal elasticity. When collagen and elastin, which are important for maintaining firmness, decrease, the skin inevitably loses its ability to support itself. That is why prompt response and care are necessary before damage accumulates!
<When the dermal layer is damaged?>
-
Overall facial elasticity decreases
-
Skin becomes even drier
-
Fine lines, nasolabial folds, and other wrinkles deepen
-
Pores enlarge and skin texture becomes rough
-
Volume is lost, causing hollowness

Thermage FLX
A treatment that can improve the overall condition of the dermal environment is Thermage FLX! Thermage FLX is a lifting device that delivers radiofrequency energy deep into the dermal layer to stimulate collagen regeneration. Rather than using high-temperature heat, it generates deep heat within the dermis through consistent radiofrequency thermal energy, which promotes collagen and elastin remodeling.
It comes with two customized tips that can be applied not only to the entire face but also to delicate areas such as around the eyes, allowing area-specific lifting. For example, the 4.0 cm² Face Tip is suitable for larger areas such as the jawline and cheekbones, while the 0.25 cm² Eye Tip allows delicate control specifically for the skin around the eyes. Another point to remember is that it can act at different depths and intensities depending on the area.

Principle and advantages
Let’s take a closer look at the principle. The radiofrequency energy of Thermage FLX induces a thermal reaction in the dermal layer. This raises the temperature inside the dermis! If a certain temperature is maintained for a set period of time, collagen tissue undergoes denaturation. During this process, collagen and elastin tissue are remodeled, and new collagen is also produced.
Thanks to this, you can feel a firm tightening effect immediately after the lifting treatment! Then, over time, various elasticity-related effects from collagen regeneration naturally appear on the face. Meanwhile, many people are also concerned about pain. Thermage itself is equipped with cooling and vibration systems, and thorough anesthesia is performed before the procedure, so there is no need to worry too much :)

-
Deep heat generated within the dermis through radiofrequency
-
Collagen and elastin remodeling
-
New collagen is produced, creating an elasticity effect
-
Pore tightening, improvement of fine wrinkles, and enhanced skin density

Principle and advantages
Mark-Vu diagnostic system
To accurately assess the firmness of the dermal layer, it is difficult to judge by observing only the skin surface. Therefore, precise observation deep within the skin is necessary! This is made possible by Mark-Vu. The Mark-Vu diagnostic system uses camera-based analysis to help measure skin depth, elasticity, pore condition, wrinkles, and more in detail.
Based on the imaging results, the lifting device and treatment range most suitable for the current skin condition are planned. Rather than relying only on intuition, it is very useful because it allows customized treatment based on objective diagnostic data. Please note that it can also be used for pigmentation treatment, scar treatment, and skin booster procedures in addition to lifting!
