XERF skin tightening
XERF dual-frequency RF skin tightening treatment utilizes the latest dual-frequency, monopolar radiofrequency technology with an output of up to 400W. It generates heat by inducing the rotation of water molecules within the skin, raising the temperature of target tissues to 45–60°C.
This process tightens structures ranging from the dermis and reticular fibrous septa down to the superficial musculoaponeurotic system (SMAS), while simultaneously activating fibroblasts to stimulate collagen regeneration, thereby achieving tightening and lifting effect.

Functions
- Reduces wrinkles, leaving the skin refined and smooth
- Increases skin elasticity and improves sagging
- Lifts the cheek bones, creating a fuller look and more defined contours
- Reshapes the jawline and reduces the appearance of a double chin
Advantages
Unique dual-frequency radio waves
By combining dual-frequency RF (6.78 MHz + 2 MHz), RF energy is delivered to deep fat layers and the fascia, providing sustained heating and resulting in significantly enhanced firming and lifting effects.

Three Different Treatment Depths
There are three distinct treatment depths—shallow, middle, and deep—capable of heating tissues at various levels.
Patented Wave Fit Pulse
Utilizing up to 12 different energy levels—incorporating pauses and cooling pulses—the treatment first heats the skin with high energy and then maintains the temperature with an appropriate energy level, ensuring a safe and painless procedure.
Intelligent cooling system
A high-efficiency cooling spray is released prior to the RF pulse to pre-cool the skin and soothe the sensation of heat, significantly enhancing treatment comfort; combined with real-time temperature monitoring, the device automatically halts RF output if excessive heat accumulates.
Spider-web pattern treatment cartridges
It eliminates RF edge effects, resulting in more uniform and stable energy transmission and effectively preventing overheating.
World’s largest facial treatment tip
It features a 2 x 3 cm facial treatment tip with a treatment area of up to 6 cm²—50% larger than comparable devices—enhancing coverage, energy delivery, and heat accumulation.
