Thermage FLX Effects and Characteristics by Area: A 4th-Generation Lifting Guide for Skin Elasticity
For those concerned about sagging skin elasticity and a collapsing jawline as they age, we detail the principles and advantages of the 4th-generation radiofrequency lifting, Thermage FLX. Discover the tightening effects through dermal collagen regeneration and customized treatment methods for each area.

Hello. This is 345 Skin Clinic. As we age, skin elasticity naturally decreases, and the jawline or cheek lines become blurred, leading to a change where the overall facial contour feels heavy. In particular, many people look for effective lifting procedures because of sagging cheeks or deepening wrinkles around the nasolabial folds and mouth.
Today, we will take a detailed look at the characteristics and expected changes of Thermage FLX, a premium radio frequency (RF) lifting procedure performed at 345 Skin Clinic.

What is Thermage FLX? The Principles of 4th-Generation RF Lifting
Thermage FLX is a lifting device that precisely delivers radiofrequency energy to the dermal layer of the skin to induce the regeneration and contraction of collagen. You can expect a tightening effect that firmly fills the skin from within, helping to create a smooth facial line.
In particular, the 4th-generation device, FLX, has significantly improved energy efficiency and output stability compared to previous generations. This has the advantage of allowing for more uniform and precise improvement of elasticity across the entire face.

The before and after photos above are of an actual patient who received the Thermage FLX treatment at 345. You can see that the blurred jaw and mouth lines have become more defined, and the overall skin texture has been evenly refined. (※ Treatment results may vary depending on the individual.)

Thermage 3rd Gen vs. 4th Gen: What Has Changed?
Compared to the existing 3rd-generation (CPT) device, Thermage FLX shows a significant difference in the accuracy of energy delivery and treatment efficiency.
- Enhanced Comfort: The vibration function and cooling system are optimized to reduce discomfort during the procedure.
- Precise Tightening: The 'AccuREP™' algorithm technology is applied to emit optimal energy with every shot.
- Reduced Treatment Time: The larger tip area allows for deep and even energy delivery in a shorter amount of time.

Adherence to Genuine Products and Exact Dosage for Safe Procedures
For highly satisfactory results, it is essential to use genuine equipment and genuine tips. Thermage tips are strictly for single use; reusing them not only decreases effectiveness but can also increase the risk of side effects such as skin burns.
- Face Tip: Used to improve overall facial elasticity and double chins.
- Eye Tip: A dedicated tip for the thin and sensitive eye area, helping to improve eye wrinkles.
345 Skin Clinic strictly adheres to the use of genuine tips and the one-tip-per-person principle, enhancing the reliability of our procedures.

Recommended Treatment Combinations with Thermage FLX
Depending on individual skin concerns, combining Thermage with other procedures can yield synergistic effects.
| Combined Procedure | Expected Effects |
|---|---|
| Ultherapy | Refines facial lines and strengthens elasticity through layer-by-layer skin lifting. |
| Skin Botox | Improves fine lines on the skin's surface and creates a smooth skin texture. |
| Rejuran / Juvelook | Enhances hydration and regenerative power by improving the internal skin environment. |

345 Skin Clinic's Precision Diagnosis System
Effective lifting goes beyond simply shooting energy; it begins with accurately understanding each individual's fat volume, muscle distribution, and skin thickness. At our clinic, we use the MarkVu 4-Light Source Analysis System to scientifically diagnose your current skin condition and establish a customized treatment plan.
If you are concerned about sagging skin, we encourage you to find the most suitable elasticity improvement solution for yourself through a diagnosis by our experienced medical staff.




Frequently Asked Questions
How does Thermage FLX improve skin elasticity?
Thermage FLX precisely delivers radiofrequency energy to the dermis layer of the skin, inducing collagen regeneration and contraction. This allows for a tightening effect that fills the skin from within, helping to create a smoother facial contour.
What are the differences between Thermage FLX and the existing 3rd generation Thermage?
Thermage FLX has improved accuracy of energy delivery and treatment efficiency compared to the 3rd generation device. It reduces discomfort during treatment with optimized vibration function and cooling system, allows for precise tightening with an automatic adjustment algorithm, and shortens treatment time with a wider tip area.
Is it important to use genuine tips during Thermage FLX treatment?
Yes, using genuine tips is very important. Thermage tips are designed for single use, and reusing them not only diminishes the effect but also increases the risk of side effects such as skin burns. It is recommended to receive treatment at a clinic that adheres to the principle of using genuine devices and genuine tips.
What effects can I expect after Thermage FLX treatment?
After Thermage FLX treatment, you can expect overall skin elasticity improvement and facial contour refinement through collagen regeneration within the skin. Specifically, you may experience a clearer jawline and mouth area, and a more even skin texture.
What treatments are good to receive with Thermage FLX?
Thermage FLX can achieve synergistic effects when combined with other treatments such as Ultherapy, Skin Botox, or Rejuran/JuveLook, depending on individual skin concerns. Ultherapy helps with layer-by-layer skin lifting, Skin Botox improves fine wrinkles, and Rejuran/JuveLook helps improve the internal skin environment.
