No
The description focuses on microcurrent stimulation controlled by an MCU with adjustable intensity levels, and there is no mention of AI or ML terms, image processing, or data sets for training/testing.
No
The device is described as being for "aesthetic purposes" and "cosmetic effect" and is not indicated for treating or diagnosing any disease or condition. Its purpose is for facial stimulation and wrinkle removal, which are considered cosmetic rather than therapeutic.
No
The device description states its purpose is to "stimulate facial tissues for aesthetic purposes" and to achieve "cosmetic effect," with no mention of diagnosing conditions.
No
The device description explicitly states it is a hand-held hardware device with a main unit, charging station, battery, and microcurrent output stimulation function controlled by an MCU.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as "to stimulate facial tissues for aesthetic purposes." This is a cosmetic application, not a diagnostic one.
- Device Description: The description focuses on the physical characteristics and the mechanism of action (microcurrent stimulation of facial skin) for cosmetic effect. There is no mention of analyzing biological samples (blood, urine, tissue, etc.) which is a hallmark of IVD devices.
- Lack of IVD-related information: The document does not contain any information typically associated with IVD devices, such as:
- Analysis of biological samples.
- Detection or measurement of specific analytes.
- Diagnostic claims or intended use for diagnosing, monitoring, or treating a disease or condition based on in vitro analysis.
- Performance metrics like sensitivity, specificity, PPV, NPV, which are crucial for evaluating the accuracy of diagnostic tests.
The device is described as a hand-held, non-sterile, reusable device for home use, designed for cosmetic facial stimulation. This aligns with the characteristics of a general wellness or aesthetic device, not an IVD.

Device Description
The Microcurrent device (Model: HBR2-1) is a hand-held, non-sterile, reusable device designed to achieve the cosmetic effect. The device consist of main unit and wireless charging station with undetachable USB cable. The device is supplied by internal rechargeable lithium battery. It can be recharged by external charger through the charging station.
The device design with Micro current output stimulation function. The MCU-controlled microcurrent circuit generates a low-frequency microcurrent which will applied in the facial skin to do facial stimulation. In the microcurrent stimulation mode, there is ten levels of output intensity which would be adjusted by the button in the device.
The device is only intended for home use.

Dear Jet Li:
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
1
statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device 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/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) 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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
