Key Answer

How does XERF lifting work?

XERF is a non-surgical lifting treatment that uses monopolar radiofrequency (RF) at two frequencies, 6.78 MHz and 2 MHz, to support collagen renewal at multiple skin depths. Skin surface temperature is monitored with every shot and the output is adjusted automatically when it reaches 43°C, and one of four effector sizes is chosen for each area. A session takes about 15–30 minutes, with numbing cream used when needed. Collagen remodeling continues over the following weeks, and visible changes usually appear over 1–3 months and vary by individual.

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.
