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

What is 448 kHz Radiofrequency (RF)?

Radiofrequency (RF) 448 kHz is a non-invasive aesthetic technology designed for skin and body treatments. It delivers controlled thermal energy at a precise 448,000 Hz frequency into deep tissues, helping to stimulate collagen production, improve blood circulation, support fat metabolism, and tighten the skin.

This technology is integrated into the Fever Master RF Machine, a professional platform widely used in aesthetic clinics for facial rejuvenation, body contouring, and physical therapy applications.

How 448 kHz CET & RET Technology Works for Body Contouring

The 448 kHz CET RET system is an advanced radiofrequency (RF) technology that works through two complementary modes to
deliver effective body sculpting and skin treatment results. By adapting energy delivery based on tissue type,
it ensures precise and efficient treatment at different depths.

CET (Capacitive Electric Transfer)

CET primarily targets the superficial tissues (3–5 cm deep) and the mid-dermal layer of the skin. By delivering gentle and evenly distributed radiofrequency energy, it achieves the following benefits:

• Improve skin firmness and elasticity
• Promotes microcirculation
• Stimulates collagen production
• Improves skin texture and tone

Applicable Areas: Face, neck, and other delicate skin regions

RET (Resistive Electric Transfer)

RET mode delivers energy to deep tissues to generate intense thermal energy. This offers the following benefits:

• Promotes fat metabolism
• Facilitates lymphatic drainage
• Reduces localized fat accumulation
• Enhances body contour firmness

Applicable Areas: Abdomen, Thighs, Arms, Back

These two modes deliver energy precisely based on tissue resistance, ensuring safe, precise stimulation of both surface and inner layers. The 448 kHz 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.
