# Intended Use / Indications for Use
The STOP U device is intended for use in the non-invasive treatment of mild to moderate facial wrinkles for adult users who have Fitzpatrick Skin Types II-IV.
# Device Description
The STOP U device delivers RF current into the skin to generate heat through electrical impedance in the dermis and subcutaneous layers. The device consists of the following components and accessories: The STOP U device (applicator unit), the STOP U Power Supply and the STOP Preparation Gel.
# Technological Characteristics
The STOP U device delivers RF energy at a frequency of 1 MHz and a maximum output RMS power of 5.7 watts into the skin through its electrodes. The device generates heat through electrical impedance in the dermis and subcutaneous layers. The temperature sensor, located between the electrodes constantly monitors the skin temperature and disables RF transmission once the desired skin temperature is obtained.
## Performance Data
Pollogen conducted several performance tests to demonstrate that the STOP U device complies with performance standards and that it functions as intended.
- STOP U Electrical safety and compatibility testing was performed to validate the STOP U power control and accuracy in reference to the user's input.
- STOP U over-heating safety testing was performed to validate the conformity with the STOPU's design requirements and specifications for its temperature sensor and profile in reference to the user's input.
- -The STOP U software was validated as required.
In all instances, the STOP U device functioned as intended and observations were as expected.

## Clinical performance data
#### Safety & Effectiveness
The effect of treatment of mild to moderate facial wrinkles using the STOP U was tested in a clinical trial that was conducted to support the clearance of the prescription version of the STOP U device (K140255). Since the over-the-counter (OTC) version of the STOP U device is identical to the prescription version, this data is also applicable to support the safety and effectiveness of the OTC device.
Altogether, 40 subjects (37 female and 3 male) were enrolled in the study. Subjects were treated for improvement of facial wrinkles appearance and were followed for 3 months post last

treatment. In order to assess safety, adverse events occurrence was monitored before and after each treatment and at follow up visits. In order to evaluate treatment efficacy, pre and post treatment photos were introduced to three uninvolved physicians for blinded evaluation based on Fitzpatrick Wrinkle and Elastosis scale.
Over 80% of the subjects showed at least one grade improvement in Fitzpatrick wrinkle score at three months follow-up post treatment based on objective evaluations of the baseline and three months follow-up photographs. There were no incidences of adverse effects or complications. As expected, mild to moderate erythema and mild edema were detected at the site of treatment immediately after treatment. All cases resolved without treatment within a few hours. Treatment was well tolerated with minimal to no pain in the majority of study subjects. The data reported in this study clearly indicates that the Stop U provides a safe and effective treatment for facial wrinkles.
## Usability, Self-selection & Labeling Comprehension
Furthermore, Pollogen conducted a usability study for the STOP U device which was divided into two stages:
- Stage one Self-Selection Study of the STOP U Device; 1.
- 2. Stage two - Human Factors Validation of the Pollogen STOP U Device.
The Self -Selection study using the final STOP U packaging design produced a correct self-selection rate that met Pollogen's goal. The final packaging design promotes correct self-selection and adequately explains user eligibility to potential users in the real world.
61 subjects (39 female and 22 male) which had successfully identified themselves as potential device users participated in the Human Factors validation with 100% success rate. These results indicated that the design of the STOP U and its associated instructional materials facilitated safe use of the device.
