Intended Use

The NuFACE Mini Device is intended for facial and neck stimulation and is indicated for over-the-counter use.

Device Description

The NuFACE® Mini Device is an over- the- counter facial and neck toning device. The chrome plated dual spheres of the NuFACE® Mini are designed to gently glide over the skin to deliver low-level electrical impulses to strategic locations on the face and neck. The NuFACE® Mini electrodes are designed for optimal contact with the face.

The NuFACE® Mini microcurrent continually alternates between the positive electrodes and allows the user to adjust settings.

The NuFACE® Mini Device measures approximately 2.5" W x 4.2" D. Its outer case is injection mold thermoplastic resin. The device comes with an external Power Supply to recharge the lithium ion battery of the device when not in use. The external Power Supply is a pre- approved wall adapter. All charging circuitry is contained within the device itself.

AI/ML Overview

This document is a 510(k) Premarket Notification for the NuFACE Mini Device. It aims to demonstrate substantial equivalence to a predicate device, the NuFACE Trinity Device, rather than proving the device meets specific performance acceptance criteria through clinical studies. Therefore, much of the requested information regarding study design, sample sizes, expert ground truth establishment, and comparative effectiveness studies is not present in this type of submission.

However, based on the provided text, here's what can be extracted and inferred:

1. A table of acceptance criteria and the reported device performance

Since this filing is for substantial equivalence, the "acceptance criteria" are primarily established by the characteristics and performance of the predicate device (NuFACE Trinity). The reported device performance for the NuFACE Mini is presented as a comparison to the predicate.
