Dear Riley Chan:

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

# IV. Device Description

The Light Therapy System is an Over-the-Counter (OTC), home-use, wearable light based device, and intended for the use in treating full-face wrinkles and mild to moderate inflammatory acne. Light radiates from the inner surface of the device onto the face. This light is generated by LED with four different spectrum wavelengths: blue (460nm), amber (605nm), red (630nm) and infrared (850nm), and the device has four light treatment, that is, blue light and mixed light mode to treat acne, while amber light mode and red+ IR mode to treat facial wrinkles.

The device is powered by external power supply by connecting with the power adapter and controlled by the controller that should be connected to the main unit. The device's power-on/off, mode switch and treatment time adjustment can be operated by the controller. The device will automatically shut down when the treatment time is over.

# V. Indications for Use

Blue light: Treatment of mild to moderate inflammatory acne.

Red+IR light: Treatment of facial wrinkles.

Amber light: Treatment of facial wrinkles.

Mixed light: Treatment of mild to moderate inflammatory acne.

# VI. Comparison of Technological Characteristics With the Predicate Device

The Light Therapy System has the same intended use as the predicate devices. The technological characteristics such as wavelength, intensity, are similar to the predicate devices. Any minor differences between the subject device and the listed predicate devices do no raise any issues of safety or efficacy. Performance data supports that the device is safe and as effective as the predicate devices for its intended use.

Therefore, the Light Therapy System may be found substantially equivalent to its predicate devices.
