Intended Use

NuFACE FIX Device is intended for facial stimulation and is indicated for over-the-counter cosmetic use.

Device Story

NuFACE FIX is a handheld, battery-powered device for over-the-counter cosmetic facial stimulation. It features two fixed, chrome-plated spherical electrodes that deliver low-level electrical impulses (microcurrent) to targeted facial areas. The device requires the use of a conductive gel. Operation involves pressing an on/off button; the device provides tactile feedback every 5 seconds to cue the user to relocate the device. The microcurrent output is a constant biphasic square wave. The device is intended for home use by consumers to provide facial stimulation. The output is designed to be safe and effective for cosmetic purposes, with automatic shut-off after 3 minutes to manage usage duration.

Clinical Evidence

No clinical data. Safety and effectiveness were demonstrated through bench testing, including electrical safety (IEC 60601-1 series), electromagnetic compatibility (IEC 60601-1-2), and usability engineering (IEC 62366).

Technological Characteristics

Handheld device with injection-molded thermoplastic housing. Powered by internal rechargeable lithium-ion battery. Delivers microcurrent via two chrome-plated spherical electrodes. Output: constant biphasic square wave (10 positive/10 negative pulses), 28 VDC max, 200 μA max current, 8.3 Hz frequency. Connectivity: user-supplied 5V USB port for charging. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-10, IEC 60601-1-11, IEC 62366, IEC 62133.

Indications for Use

Indicated for over-the-counter cosmetic facial stimulation.

Dear Donald Ellis:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration. listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801; medical device reporting (reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
