I. What is Thermage FLX? Why is it called “Phoenix Radio Waves”?
Thermage FLX (commonly translated in Chinese as “Phoenix Radio Waves” or “Radio Wave Facelift”) is currently the leading option worldwide.The most well-known and classic non-invasive skin tightening treatmentDeveloped by the American company Solta Medical, the first generation was launched in 2002, giving it a history of over 20 years — it truly stands as the industry leader in the radiofrequency category.
What’s currently widely used in the South Korea market is4th Generation FLX VersionThe three letters FLX stand for:
- F: Faster
- L: Leverage (for greater efficiency)
- X: Better Experience
A one-sentence summaryPhoenix Radio Waves = No surgery, no injections—uses high-frequency radio waves to “tighten” loose skin.
II. How Thermage FLX Works｜Why Does It Tighten the Face?
Thermage FLX uses high-frequency radiofrequency waves that vibrate at around 6.78 million times per second to generate heat in the skin. Through its 3D IPCHEA heating mechanism, it delivers energy evenly deep into the dermis, approximately 2–3 mm down. 。
When heat energy is applied, it produces two effects:
- Shrink immediatelyThe existing Collagen fibers contract when heated, creating an immediate sense of firmness.
- Long-term Renewal: Stimulates the regeneration and restructuring of Collagen and elastin, with results visible inContinuous improvement within 2–6 months
The key difference in one sentenceUltherapy works like a “stapler,” securing loose fascia back in place, while Thermage functions like an “iron,” smoothing and tightening the entire skin surface.
