Our Lutronic XERF treatment in Los Angeles is designed for patients who want visible tightening without needles or downtime. The technology combines 6.78 MHz and 2 MHz frequencies, and uses Wave Fit pulse plus integrated cryogen cooling to keep the surface comfortable while energy is delivered precisely.
How it Works
We start with an expert assessment of your skin, facial structure, and goals. XERF adapts to each patient using real-time impedance feedback, with multiple depth settings and intensity levels so your plan is truly personalized.
During treatment, multifrequency monopolar RF energy is delivered across different skin depths. The system uses Wave Fit pulse technology and integrated cryogen cooling for a consistently comfortable experience, without the typical numbing prep that many patients dislike.
There is no downtime, most patients return to work, errands, and social plans the same day. Collagen-building continues over time, which is why results can look better in the weeks after treatment.
