Safety and Efficacy Evaluation of the Xerf Device for Aesthetic Treatments

The goal of this clinical study is to evaluate the safety and clinical effectiveness of the XERF noninvasive dual-frequency monopolar radiofrequency device for aesthetic improvement of facial aging, including fine lines and wrinkles, eyebrow lifting, and tightening of lax tissue in the lower face, submental area, and neck in healthy adults.

Up to 60 participants may be enrolled across up to five clinical sites in the United States. Participants receive XERF treatments using 6.78 MHz and 2.0 MHz energy; most undergo two sessions approximately four weeks apart (the protocol allows up to three). Standardized photographs are taken at baseline and follow-up visits.

Outcomes are assessed approximately 30 and 90 days after the final treatment. Effectiveness is evaluated using investigator-assessed global aesthetic improvement and participant-reported satisfaction, while safety and tolerability are assessed through procedural pain ratings and monitoring of adverse events throughout the study.

Treatment and study plan

Noninvasive dual-frequency monopolar radiofrequency

Device

Participants received treatment with a noninvasive contact monopolar radiofrequency (RF) device (XERF) operating at 6.78 MHz and 2.0 MHz. The device delivers RF energy using depth-dependent settings (Shallow, Middle, and Deep) selected based on the target condition and facial anatomic zone. Treatments were performed with the EFFECTOR 60 tip using sliding mode, stamping mode, or a combination, after facial cleansing and application of a thin film of ultrasound gel. Adjustable cryogen gas cooling (ICD Levels 1-3) was used for epidermal protection and comfort; no topical anesthesia was used. Participants underwent two treatment sessions approximately 4 weeks apart (the protocol allowed up to three sessions). The number of shots and total energy delivered (joules) were recorded for each treatment area.

Primary outcomes

  1. Clinician-Scored Global Aesthetic Improvement Scale (GAIS) Responder Rate

    Time frame: 90 days after the final treatment

    Proportion of participants with a GAIS score ≥3 (on a 5-point scale, 1-5), assessed by site principal investigators using standardized clinical photographs. A GAIS score ≥3 was considered an effective clinical improvement.

Secondary outcomes

  1. Patient Satisfaction Score (PSS) Responder Rate

    Time frame: 30 and 90 days after the final treatment

    Proportion of participants with a Patient Satisfaction Score (PSS) ≥4 on a 6-point scale (1 = extreme dissatisfaction; 6 = significant satisfaction), assessed at follow-up visits.

  2. Clinician-Scored Global Aesthetic Improvement Scale (GAIS) Responder Rate at 30 Days

    Time frame: 30 days after the final treatment

    Proportion of participants with a GAIS score ≥3 on a 5-point scale (1-5), assessed by site principal investigators using standardized clinical photographs. GAIS ≥3 was considered effective improvement.

  3. Incidence of Adverse Events

    Time frame: From first treatment through 90 days after the final treatment

    Number and proportion of participants experiencing treatment-emergent adverse events, documented throughout the study and follow-up.
