What is XERF lifting in Korea?
XERF is a radiofrequency device that uses two monopolar RF frequencies together, 6.78 MHz and 2 MHz (2RF). The clinic describes 6.78 MHz as working on the superficial layer (upper dermis near the epidermis) and 2 MHz on deeper layers, and states that three depth settings (Shallow, Middle, Deep) and ten energy levels are adjusted to the area and skin condition.

How it is done
The depth settings described by the clinic are Shallow (upper dermis), Middle (lower dermis, the collagen-dense layer) and Deep (the subcutaneous fat layer up to just above the SMAS). The clinic explains that skin temperature is monitored in real time with each pulse and RF output stops automatically if the skin surface exceeds 43Β°C, and that a three-stage ICD cooling system (cooling gas spray) cools the epidermis. Depth setting and energy level are chosen according to the area and skin condition.
