Intended Use

The CurrentBody Skin RF device is an over-the-counter home use device intended for non-invasive treatment of mild to moderate facial wrinkles for adults with Fitzpatrick skin types I-IV.

Device Story

CurrentBody Skin RF is a handheld, non-invasive, non-ablative device for home use by lay persons. It generates bipolar radiofrequency (RF) energy pulses (1 MHz) emitted into the skin via four electrodes to heat tissue, aiming to improve the appearance of wrinkles and rhytides. The device includes a user interface, power supply, RF power module, and a programmable logic controller (PLC) on a PCBA. Two redundant thermistors monitor skin temperature to maintain a target range (max 40.5 ± 0.5ºC) and adjust power output accordingly. The user applies the device to the skin; the system provides thermal feedback to ensure safety. By heating the dermis, the device intends to reduce facial wrinkles, offering a non-surgical aesthetic benefit to the user.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including electrical safety, electromagnetic compatibility, software validation, and a human factors/self-selection study. Thermal equivalence to the predicate was demonstrated via a bench experiment using porcine belly skin samples with calibrated temperature probes.

Technological Characteristics

Handheld device; ABS plastic shell; chrome-coated electrodes. Energy source: 1 MHz bipolar RF. Power: 5 ± 1 W. Safety: Two redundant thermistors for temperature control (max 40.5 ± 0.5ºC). Connectivity: None. Sterilization: Non-sterile. Software: PLC-based control. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 60601-2-2, ISO 10993-1.

### 7. NON-CLINICAL (BENCH) PERFORMANCE DATA

The following performance data (bench tests) were provided in support of the performance, safety and efficacy of the CurrentBody Skin RF device as well as the substantial equivalence determination.

# Safety Bench Tests and Verification & Validation (V&V) Summary

- . Over-heating safety. The two redundant thermistors embedded in the device constantly measure the skin temperature and constantly alter the power emitted to maintain the temperature constant within the target treatment temperature range (maximal temperature of 40.5 ± 0.5ºC). Power accuracy. The device was validated on a 200 Ω load, which is appropriate as the reference of the average load of the user. The measured total power was within the error margin, indicating that the device met the acceptance criteria.
- Parameter validation. The device was tested for its varied parameters, ● including radio frequency, pulse cycle, wave form and pulse duration. All results were within the acceptance criteria.

# Electrical safety and electromagnetic compatibility (EMC)

Electrical safety and EMC testing were conducted on the CurrentBody Skin RF device. The device complies with:

- IEC 60601-1:2005/EN 60601-1:2006, General safety standard: safety . requirements for medical electrical systems.

{6}------------------------------------------------

- IEC 60601-1-2:2014/EN 60601-1-2:2015, Medical electrical equipment . Part 1-2 - General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests.
- IEC 60601-1-11:2015, Medical electrical equipment Part 1-11 -. Requirements for the medical electrical equipment and medical electrical systems used in the home healthcare environment.
- . IEC 60601-2-2: 2017, Medical electrical equipment - Part 2-2: Particular requirements for the basic safety and essential performance of high frequency surgical equipment and high frequency surgical accessories.

## Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern because inadvertent software errors could result in skin burns to the user.

## Human Factors Validation Testing

A Self-Selection and Human Factors validation study was performed to demonstrate that users can safely and effectively self-select, prepare and perform treatment with the CurrentBody Skin RF device.

# Thermal Effects on porcine belly skin

In order to provide further evidence for the equivalence of the spatio-temporal heating profile of the subject and predicate devices, a bench experiment was conducted in porcine belly skin samples instrumented with multiple calibrated

{7}------------------------------------------------

temperature probes. Measurements showed comparable (near identical) spatiotemporal tissue heating between the subject and predicate devices.

Thus, the CurrentBody Skin RF device can be regarded as thermally equivalent to the approved Pollogen STOP U Model UXV device and no risks are raised regarding the safety and efficacy of the device.

#### 8. PERFORMANCE TESTING - ANIMAL

No animal testing was performed with the subject device.

#### 9. CLEANING, STERILIZATION, SHELF LIFE AND BIOCOMPATIBILITY

The CurrentBody Skin RF device is a non-sterile, reusable device, intended for a single user. The device cleaning instructions are based on the cleaning instructions of the predicate device due to the fact that both devices are made from the same materials and used similarly.

The shelf-life expectancy of the device is 5 years, similarly to the predicate device.

The biocompatibility evaluation for the CurrentBody Skin RF device was conducted in accordance with the FDA guidance "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing.'" September 8, 2023, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA.

#### 10. CLINICAL PERFORMANCE DATA

No clinical testing was performed with the subject device, as it is substantially equivalent to the predicate device, and thus requires no additional clinical data to prove its safety and efficacy.

{8}------------------------------------------------

#### 11. SUBSTANTIAL EQUIVALENCE

The indications for use and technological characteristics of the CurrentBody Skin RF device are substantially equivalent to the indications for use and technological characteristics of the predicate device, as can be seen in the technology comparison table below.

The design and components of both devices (i.e., power supply, RF generator and controller) are similar. The performance specifications of the CurrentBody Skin RF (i.e., RF frequency and electrical power) are substantially equivalent to those of the predicate device. The safety features and compliance with safety standards of both are similar. The body contact materials are similar. The minor differences in the technological characteristics do not raise new safety or effectiveness concerns and are demonstrated to be substantially equivalent through relevant performance tests. Furthermore, the CurrentBody Skin RF device has qualified with varied performance tests, including software validation testing, electrical and mechanical safety testing according to IEC 60601-1, electromagnetic compatibility testing according to IEC 60601-1-2, compatibility as medical electrical equipment for home healthcare environment according to 60601-1-11, and high frequency of surgical equipment according to IEC 60601-2-2. The performance tests demonstrated that the device specifications meet the system requirements and do not raise new safety or effectiveness concerns.
