Dear Alain Dijkstra:

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.

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

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).

### Comparison in Detail(s):

Note 1: Although the "Indications for Use / Intended use" is a little different from the predicate devices, the acne removal function of the model MT-12MA and MT-12MC (mode1) of subject device is consistent with predicate device (K230720), the wrinkle removal function of the model MT-12MC (mode 2) of subject device is consistent with predicate device (K221946), the wrinkle removal function of the model MT-12MC (mode 3) of subject device is consistent with predicate device (K200104). So, this difference will not affect the safety and effectiveness of the subject device.

Note 2: Although the "Power Supply" is a little different from the predicate devices, they all complied with the IEC 60601-1, IEC 62133-2, and IEC 60601-1-2 safety standards' requirements. So, these slight differences will not raise any safety or effectiveness issues.

Note 3: The wavelengths of the subject device can be covered by the predicate device. The wavelength of MT-12MA and MT-12MC Mode 1 is 630nm and 415nm, which is consistent with the predicate device 1 (K230720); The wavelength of MT-12MC Mode 2 is 830nm which is consistent with the predicate device 2 (K221946); The wavelength of MT-12MC Mode 3 is 590nm which is consistent with the predicate device 3 (K200104).

So, the treatment wavelength of the subject device is acceptable.

Note 4: Although the "Number of LEDs" is different from the predicate devices, it will not change the irradiance which is similar. So, these differences will not raise any safety or effectiveness issues.

Note 5: Although the "Irradiance", "Dose / per time" and "Treatment Time" are a little different from the predicate devices, the values of each treatment for these parameters are very close. Dose is equal to Irradiance (W/cm²) * Time (s). Through calculation, it can be concluded that the dose of the subject device at 630+415nm is 0.03 * 3 * 60=5.4J/cm², which is consistent with the dose of the predicate device (K230720) at 0.03 * 3 * 60=5.4J/cm²; The dose of subject device 830+630nm is 0.035 * 9 * 60=18.9J/cm², which is similar to the dose of predicate device (K221946) of 0.03 * 10 * 60=18J/cm², and the dose of

{9}------------------------------------------------

590nm is 0.035 * 21 * 60=44.1J/cm², which is similar to the dose of predicate device (K200104) of 0.035 * 20 * 60=42J/cm². So, these differences will not raise any safety or effectiveness issues.

- � IEC 60601-1-11 Edition 2.1 2020-07 Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance -- Collateral Standard: Requirements for Medical Electrical Equipment and Medical Electrical Systems Used in the Home Healthcare Environment.
- � IEC 60601-2-57 Edition 1.0 2011-01 Medical Electrical Equipment - Part 2-57: Particular requirements for the basic safety and essential performance of non-laser light source equipment intended for therapeutic, diagnostic, monitoring and cosmetic/aesthetic use.
- � IEC 60601-1-2 Edition 4.1 2020-09 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances -Requirements and tests.
- � IEC 62471 First edition 2006-07 Photobiological safety of lamps and lamp systems.
- � IEC 62133-2 Edition 1.0 2017-02 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications - Part 2: Lithium systems.

### 2) Biocompatibility Test

The subject device is biocompatible for its intended use. They are complied with biocompatibility standards ISO 10993-5 (Cytotoxicity), ISO 10993-10 (Sensitization), ISO 10993-23 (Skin Irritation) and ISO 10993-11 (Acute Systemic Toxicity and Material-mediated Pyrogens) and USP 151.

### 3) Software verification and validation

Software verification and validation testing were conducted and documentation was provided as recommended by FDA'S Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level concern, since a malfunction of, or a latent design flaw in, the Software Device leads to an erroneous diagnosis or a delay in delivery of appropriate medical care that would likely lead to Minor Injury.

### 4) Usability validation

Usability testing was conducted on the Face Patches (Models: MT-12MC), which complies with IEC 62366-1 and IEC 60601-1-6.

# 5) Light output
