Intended Use
SmartAppGuided™ MicroCurrent Face-Lift Pen | 6 in 1 is intended for the stimulation of neck and facial skin and is indicated for over-the-counter cosmetic use.
Device Description
SmartAppGuided™ MicroCurrent Face-Lift Pen| 6 in 1 is an over-the-counter stimulation device. Its enclosure is injection-molded thermoplastic resin with silicone embedded in it. The output contacts consist of an electrode composed of chrome-plated or titanium- gold plated sphere. The device is powered by a rechargeable lithium-ion battery and cannot be used while charging. The device produces microcurrent that is discharged through two fixed, smooth spherical electrodes, and it has 3 current intensity levels that can be adjusted by pressing the on/off button on the device. Press the on/off button to turn on the device, and two spherical electrodes provide low-level electrical pulses to the target position of the face, and when the EMS function is turned on, the vibration function is also turned on simultaneously; The device spheres are designed for optimal contact with facial skin. The device delivers microcurrent as a constant biphasic square wave comprised of 10 positive pulses followed by 10 negative pulses. The microcurrent output continuously alternates between the positive and negative spherical electrodes.
More Information

Not Found

No.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Safety Testing: Electrical, Mechanical, and Thermal Safety Testing were conducted according to IEC 60601-1, IEC 60601-1-11, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-10, ISO 10993-1, IEC 60529, IEC 62366, ISO 14971, IEC 62133.
Bench Testing: Bench testing was conducted to verify that the MicroCurrent Face-Lift Pen | 6-in-1 meets established performance requirements and waveform specifications within the designed tolerances. Testing utilized production-equivalent devices to assess waveform and output energy characteristics. A third-party accredited laboratory evaluated the device in accordance with IEC 60601-2-10. Results confirm that the waveform and energy characteristics conform to intended specifications and demonstrate substantial equivalence to the predicate device.
Software Verification and Validation Testing: Software verification and validation testing were conducted as recommended by FDA's Guidance for Industry and FDA Staff, "Content of Premarket Submissions for Device Software Functions Guidance for Industry and Food and Drug Administration Staff", issued on June 14, 2023. The software was considered a "basic" level of concern.
Animal Study: Not required.
Biocompatibility: Evaluation performed according to ISO 10993-1 and FDA Guidance "Use of International Standard ISO 10993-1". Tests conducted in accordance with ISO 10993-1:2018, ISO 10993-5:2009, ISO 10993-10:2021, ISO 10993-12:2021, ISO 10993-23:2021.

Dear Natalia Reshetnikova:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

(https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 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-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
