Dear Cassie Lee:

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.

## 4. Device Description

Looper (Model: ZX-579S) is a hand-held device for over-the-counter aesthetic purposes, it's a multifunctional comprehensive beauty instrument. It's combined with the two kinds of operation functions: SONIC and PHOTON mode.

Sonic mode: The Sonic waves can provide vibrating to facial skin. The device provides 5 vibration intensities for users to choose from.

Photon mode: The red light is intended for use in treating wrinkles on the face, and the blue light is intended for the treatment of the mild to moderate inflammatory acne. It emits energy in the red spectrum for the treatment of facial wrinkles. The therapeutic probe is designed for direct contact with the face for treatment.

The Looper device consists of an applicator and charging base. An applicator is a hand-held unit used for treatment. The treatment surface is located at the applicator tip and comes in direct contact with the skin. The charging base charging for the applicator. And there is no external data connection capability (e.g., through USB, Ethernet, WiFi, Bluetooth, etc.) for the device.

There are two keys: the PHOTON key and the SONIC key. The PHOTON is to select red light and the Sonic is to select the SONIC mode and adjust the sonic. Both keys can turn on/off the device.

#### Comparison in Detail(s): Note 1:

Although the "Main Unit Weight", "Dimensions of device", "Power source" and "Indicator" of subject device is different from the predicate devices, they are all compliance with IEC 60601-1 requirement for the product and not affect the safety or effectiveness. So the differences of function specification will not raise any safety or effectiveness issue.

# Note 2:

Although the "Irradiation area" and "Irradiance" is a little different from the predicate devices, they are all compliance with IEC 60601-1-11 and IEC 60601-2-57 requirements. So the differences will not raise any safety or effectiveness issue.

# Note 3:

The Nature of body contact is skin contact. And the contact duration is less than 24 hours. The materials and manufacturing used for the subject device are identical to those of the device K171821, and the materials have been demonstrated to conform with the following biocompatibility standards:

· ISO 10993-5:2009, Biological evaluation of medical devices - Part 5: Tests for In Vitro cytotoxicity · ISO 10993-10: 2010, Biological evaluation of medical devices - Part 10: Tests for irritation and delayedtype hypersensitivity

#### Final Conclusion:

Although there has some slight differences between with subject device and predicate device, the subject device Looper (Model: ZX-579S) is Substantial Equivalence to the predicate devices K171821, K162098 and K172909. Because compare with predicate device, the subject device is very similar in design principle, intended use, indications for use, functions, material and the applicable standards. And the subject meets the same standards as the predicate device, so the differences between subject device and predicate device do not raise and new questions of safety or effectiveness.
