Effector Surface Temperature Monitoring & ICD Cooling System
XERF monitors skin surface temperature in real time with every shot, displaying live data on both the device GUI and the handpiece screen. If the temperature reaches 43°C, the system automatically regulates RF output to prevent excessive heat buildup. Paired with a 3-step ICD cooling system that adjusts to treatment intensity, XERF minimizes skin burden to ensure a safer, more comfortable lifting experience.
Stable ICD Cooling & Collagen Remodeling
XERF delivers controlled thermal stimulation into the dermal layer to activate collagen production and tissue remodeling, initiating visible firmness soon after treatment. As collagen regeneration continues over the following 2–4 weeks, it progressively enhances skin elasticity, smooths fine lines, and refines texture for a natural, long-lasting lifting effect.
