Thermage® FLX Advanced Skin Tightening and Rejuvenation
This is a 4th-generation RF (radiofrequency) treatment device that delivers 6.78 MHz monopolar RF energy deep into the skin—from the dermal layer to the dermal–subcutaneous fat junction—inducing collagen contraction, regeneration, and visible lifting effects.
The newly integrated AccuREP™ real-time calibration algorithm calculates tissue impedance with every pulse and automatically adjusts energy delivery to create consistent and uniform thermal zones. At the same time, the integrated vibration and cooling system operates continuously to minimize discomfort during treatment.

What is Thermage® FLX ?
Thermage® FLX is the leading radiofrequency (RF) technology for non-invasive skin tightening and rejuvenation. Exclusively at Cellon Medical Group, this pioneering treatment offers impressive results with just one session, combining the most advanced RF technology with advanced cooling systems for maximum comfort and effectiveness. With Thermage® FLX, your skin is deeply renewed, while results continue to improve over the following months, offering a natural and youthful appearance.
The Thermage® FLX treatment is ideal for those who want to address skin laxity without resorting to surgical procedures. Whether it’s for the face, neck, or body, Thermage® FLX offers a comprehensive solution for skin tightening and lifting.
How Thermage® FLX Works
Thermage® FLX uses radiofrequencies (RF) to controllably heat the deeper layers of the skin that are rich in collagen. This heat causes immediate tightening of collagen fibers and stimulates the natural process of new collagen production, offering immediately visible results that continue to improve over time. The treatment is completely safe and non-invasive, with no recovery time.

STEPS
Your Guide to Thermage® FLX Treatment

At Cellon Dermatology clinic, we offer a holistic approach that aims not only at the aesthetic improvement of your skin but also at its overall rejuvenation and health. Our specialized team will guide you through every step of the process.
1. Initial Consultation
During your first visit, we thoroughly assess your skin condition and discuss your goals for tightening and rejuvenation. We examine the degree of sagging, skin quality, and areas that need improvement. Then, we determine if Thermage® FLX is the right treatment for you and answer all your questions.
2. Personalized Plan
Based on the initial assessment, we create a personalized treatment plan. We precisely determine the application areas and adjust the intensity of the treatment according to your needs. Thermage® FLX is usually a single treatment, with annual maintenance if needed.
3. Treatment Procedure
The session begins with preparation of the treatment area. Radiofrequency energy is applied with precision to deeper collagen-rich layers of the skin. Treatment typically lasts 30–90 minutes and remains comfortable thanks to advanced cooling technology.
4. Comprehensive Post-treatment Care
After treatment, we provide clear aftercare instructions. Results may be noticeable immediately and continue to improve over 2–3 months as new collagen forms. Maintenance sessions can be scheduled for long-term results.
