XERF — WOOA Plastic Surgery
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. Per the clinic website: treatment time 20–30 minutes; cream anesthesia; recovery listed as "same-day recovery possible". The duration of effect is given as 1–2 years in the information table but about 6 months in the FAQ on the same page, so please confirm at consultation.

Who this is for
- Those concerned about fine lines, skin texture or pores
- Those concerned about loss of skin elasticity
- Those concerned about facial contour lines such as the jawline or double chin
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 43°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.
