XERF™ takes a structural approach to skin tightening, using dual-frequency radiofrequency energy to target multiple tissue depths. This non-surgical treatment helps improve firmness and redefine facial contours with minimal downtime.

  • INVESTMENT

    Starting at $2200 per session.

  • RECOVERY

    XERF requires little to no downtime, with most patients returning to their usual activities immediately. Temporary redness, warmth or mild swelling may occur and generally settles within hours. Results develop gradually as collagen remodels in the weeks and months following treatment.

  • NUMBER OF TREATMENTS

    An initial course of two treatments may be recommended, depending on your skin laxity and goals. At your consultation, the KOZA team will recommend the spacing of your appointments and a maintenance plan tailored to your skin.

WHAT DOES XERF TREAT

XERF addresses facial and neck laxity, fine lines and wrinkles, and loss of firmness. Treatment can help improve jawline definition, soften the appearance of early jowls and provide a subtle lift to the brow.

HOW DOES XERF WORK

XERF uses dual-frequency radiofrequency energy—6.78 MHz and 2 MHz—to deliver controlled heat at shallow, middle and deeper tissue levels. This supports collagen remodelling for firmer, smoother skin over time. Integrated cooling helps protect the skin’s surface, while adjustable depth and intensity settings allow treatment to be personalised.
