No
The description details a device with fixed modes (Sonic and Photon) and user-selectable intensity levels. There is no mention of adaptive behavior, learning from data, or any components typically associated with AI/ML. The performance studies listed are standard electrical and safety tests, not AI/ML model validation.
Yes.
The device is indicated for "treating wrinkles on the face" and "treatment of the mild to moderate inflammatory acne" which are therapeutic purposes. It also lists several IEC standards that apply to medical electrical equipment, including those specifically for "therapeutic" use.
No
This device is designed for aesthetic and therapeutic purposes (treating wrinkles and acne), not for diagnosing medical conditions.
No
The device description clearly states it is a "hand-held device" and includes physical components like an "applicator" and "charging base" with a "treatment surface" that comes into direct contact with the skin. It also mentions "two keys" for operation. While it mentions compliance with IEC 62304 (Medical device software), the device itself is a physical hardware device with embedded software, not a software-only medical device.
Based on the provided information, the Looper (Model: ZX-579S) device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Looper's Function: The Looper device is a hand-held device that applies light (red and blue) and sonic vibrations directly to the skin for aesthetic and therapeutic purposes (treating wrinkles and acne). It does not analyze any biological samples taken from the body.
The device's intended use, description, and the standards it was tested against (which are related to medical electrical equipment and light therapy, not diagnostics) all indicate that it is a therapeutic and aesthetic device, not an IVD.

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.
