RF 448 kHz Technology: Precision Energy for Skin & Body Renewal

What is Radiofrequency RF 448 kHz?

Radiofrequency (RF) 448KHz is a non-invasive technology for skin and body care that uses a precise 448,000 Hz frequency to deliver thermal energy to deep tissues, effectively activating bioregeneration, improving blood circulation, reducing fat and tightening skin.

This technology is at the heart of the Fever Master Machine, a versatile RF platform trusted by aesthetic clinics for facial rejuvenation, body contouring and physical therapy.

How Does 448K CET RET Work?

The 448K CET RET system works through two synergistic modes:

CET (Capacitive Electrical Transmission):

Targets the superficial and mid-dermis to help firm the skin and stimulate microcirculation. This gentle and effective treatment is suitable for delicate skin areas such as the face and neck.

RET (Resistance Electrical Transmission):

Delivers energy to deeper structures to promote deep heating, detoxification, lymphatic drainage and body contouring.

These two modes deliver energy precisely based on tissue resistance, ensuring safe, precise stimulation of both surface and inner layers. The 448KHz frequency also stimulates the sodium-potassium exchange pump in cells, enhancing metabolic activity and tissue regeneration.

The Fever Master Machine utilizes this dual-mode technology with adjustable intensity for various treatment goals, making it highly versatile.
