The XERF system offers the world’s first multifrequency monopolar RF treatment. By combining both 6.78 MHz and 2 MHz frequencies, XERF can deliver energy not just deeper, but exactly where you need it most, creating smoother and tighter skin. The XERF system leverages Wave Fit™ pulse and Advanced Integrated Cryogen Delivery cooling technology to control energy delivery while maintaining surface temperature, for a Never-Numb™ treatment. XERF sessions require a shorter room time vs. similar treatments that require numbing, potentially increasing the number of patients that can be treated per day.
What internal temperatures are created by the XERF system, and how were they measured?
In in-vivo studies, Cynosure Lutronic measured internal skin temperatures of 50°C, 60°C, and 70°C using ultrasound-guided fiber-optic imaging. Following the XERF treatment, histological analysis confirmed collagen remodeling
How do you know XERF treatments strengthen collagen and tighten the skin?
Histological evidence from in-vivo porcine studies shows increased thickening and tightening of collagen bundles at multiple tissue depths, along with an observable upward pull in the fascia.
How do you know how deeply the XERF system delivers RF energy?
Histological analysis from multiple clinical studies confirms the XERF system delivers RF energy to the SMAS (Superficial Musculoaponeurotic System). The SMAS is a foundational tissue layer beneath the skin that plays a key role in lifting and tightening sagging skin and reducing the appearance of jowls.
