XF-680 4D RF Skin Tightening System — Dual-Frequency Monopolar RF with ICD Cooling
Simultaneous 6.78MHz + 2MHz delivery reaches SMAS layer. Real-time impedance feedback, Wave Fit Pulse technology, CE approved. XERF-compatible technology for clinics and distributors.
3 Depth Settings
ICD Cooling
10 Intensity Levels
CE Approved
Product Overview
The XF-680 is a non-invasive dual-frequency monopolar RF system that delivers simultaneous 6.78 MHz and 2 MHz radiofrequency energy. Unlike single-frequency RF devices, the dual-frequency approach treats skin across shallow, middle, and deep layers in a single pass — reaching the SMAS (Superficial Musculoaponeurotic System) layer at approximately 4.5mm depth for comprehensive skin tightening and collagen remodeling.
The system features Wave Fit Pulse technology which divides each treatment shot into 12 sub-pulses in a wave-like energy pattern, paired with Integrated Cryogen Delivery (ICD) for simultaneous cooling. The 3-way spider-pattern handpiece tip ensures uniform energy distribution without edge heat accumulation. Real-Time Accurate Impedance Feedback continuously adapts energy output to each patient’s unique skin profile for safe, personalized treatments.

Key Features
Dual-Frequency Simultaneous RF
6.78 MHz + 2 MHz delivered simultaneously in a single pass. Treats from superficial dermis down to SMAS layer (~4.5mm) for multi-depth collagen stimulation that single-frequency devices cannot achieve.
Wave Fit Pulse Technology
Each treatment shot is divided into 12 sub-pulses with energy moderated in a wave-like pattern. This ensures comfortable heating to remodeling temperatures while minimizing discomfort — no numbing required.
Integrated Cryogen Delivery (ICD)
Every RF sub-pulse is paired with a simultaneous cryogen cooling sub-pulse. The epidermis stays protected while deep dermal layers reach therapeutic temperatures for safe, comfortable treatments.
Spider-Pattern Energy Distribution
The 3-way spider-web radiation pattern delivers uniform energy across the treatment tip, preventing edge heat accumulation — a common pain point with conventional monopolar RF devices.
Real-Time Impedance Feedback
Built-in Accurate Impedance Feedback continuously measures skin impedance before and during each pulse, adapting energy output in real time to each patient’s unique skin profile for personalized safety.
Zero Downtime, No Numbing
Patients walk in and return to daily activities immediately. The ICD cooling + Wave Fit Pulse combination means most patients require no topical anesthetic. Suitable for Fitzpatrick skin types I through VI.
Treatment Applications

What’s in the Box
Effector Tips Are Consumables
The 40 included effector tips are single-use consumables. Reorder replacements from us anytime to keep treatments running without interruption.
- $80 USD per tip — sold individually
- ~600 shots per tip — each tip is rated for about 600 firings
- ~900 shots per full-face + neck session — a single treatment uses more than one tip
We recommend keeping a buffer of replacement tips on hand so you never have to pause a patient's treatment schedule.
