XERF
The world's first dual-frequency monopolar RF system — delivering 6.78 MHz and 2 MHz simultaneously to tighten skin at every layer from the upper dermis down to the structural SMAS, with no needles, no numbing, and no downtime.

About XERF
XERF is the most advanced non-invasive radiofrequency tightening system available — and the world's first to deliver two RF frequencies simultaneously. Developed over seven years in South Korea before receiving FDA clearance in the United States, XERF represents a meaningful leap beyond older single-frequency RF technologies. The 6.78 MHz frequency targets the upper dermis, remodeling collagen and elastin fibers responsible for surface texture and fine lines. The deeper 2 MHz frequency reaches the SMAS — the Superficial Musculoaponeurotic System — the same structural layer addressed in surgical facelifts, governing the lift and definition of the jawline, cheeks, and neck. Treating both simultaneously, within a single session, is what separates XERF from all prior RF devices. The system features real-time Accurate Impedance Feedback, which continuously analyzes each patient's skin profile and allows AI-guided energy delivery to ensure consistent, safe, and personalized results. Integrated cryogen cooling protects the skin surface throughout, making the treatment comfortable without topical numbing. With 10 intensity levels and 3 depth settings, the provider can precisely calibrate each pass for the patient's anatomy and goals. Patients typically notice mild, immediate tightening and firmness from their first session. Progressive collagen remodeling continues over 4–12 weeks, with the full result developing gradually. Many patients sustain visible benefit for 12 months or longer — particularly with good skincare, sun protection, and a maintenance plan. Unlike RF microneedling, which requires numbing and has several days of recovery, XERF needs no preparation and no downtime. You can resume all activities immediately after treatment. XERF is appropriate for face, jawline, jowls, neck, brows, cheeks, arms, and abdomen, and is generally safe across all skin types and tones. It is an excellent option for patients with mild to moderate laxity who want meaningful structural tightening without surgery, injectables, or recovery time.
