Thermage FLX RF System Facts


Skin tightening


Mechanism of action

Pulsed RadioFrequency (RF) technology heats the deep, collagen-rich layers of the skin, producing new collagen growth over time. The new collagen growth tightens the skin. Simultaneous rotational vibration is used to cool the skin’s surface for patient comfort.

How it works

The device delivers radiofrequency energy while the tip vibrates simultaneously. The body’s healing response stimulates the production of new collagen. As the new collagen grows, the skin tightens with continued improvement up to six months.

FDA Cleared

Yes, the Radiofrequency component of the device is cleared for facial and periorbital  wrinkles. (these indications not addressed in this Report)
