The TheraFace LED device is a lightweight device which uses specified wavelengths of LED light. For LED light irradiation function, the device produces light in the red light region of the spectrum (633±10nm), combination of IR and Red light (830nm±10nm&633 ± 10 nm), or in the blue light region of the spectrum(415±10nm).

The TheraFace LED device consists of a main control unit and its attachment applicators for the LED irradiation ring, which can be controlled by the device control button. The device is powered by one internal lithium rechargeable battery which can be charged by an external batterv charger.

Red light mode: In Red light irradiation mode, the device utilizes Light Emitting Diodes to emit The output is adjustable to one wavelength with a narrow spectral bandwidth in red light. It provides narrow bands of red-light energy and is intended to treat periorbital 633±10nm. wrinkles.

Blue light mode: In blue light irradiation mode, the device utilizes Light Emitting Diodes to emit blue light. The output is adjustable to one wavelength with a narrow spectral bandwidth in 415 ±10nm. It provides narrow bands of blue light energy to facial skin, and is intended to treat mild to moderate inflammatory acne.

Red+ IR mode: When the device is operated in the red combined with infrared light mode, it emits LED light in the RED (633 nm) and IR (830 nm) spectrum on facial skin. It is intended to treat periorbital wrinkles.

AI/ML Overview

This document is a 510(k) summary for the TheraFace LED device, asserting its substantial equivalence to previously cleared devices. It does not contain information about acceptance criteria, device performance metrics, or study details in the format requested.

Specifically, the document states:

"There were no clinical studies performed." (Page 9)
It outlines "Performance Standards Applied" (Page 8-9) which are a series of bench tests for electrical safety, electromagnetic compatibility, and biocompatibility, designed to show the device meets general safety standards, similar to predicate devices. These are not acceptance criteria related to efficacy or clinical performance.
It mentions "PERFORMANCE TESTING BENCH" (Page 9) including a "Usability Study Report" and "TheraFace LED Light Power Density Test Report," but provides no details on acceptance criteria or results from these reports.

Therefore, I cannot fulfill your request for:

A table of acceptance criteria and the reported device performance.
Sample size used for the test set and data provenance.
Number of experts used to establish ground truth and their qualifications.
Adjudication method for the test set.
Multi-reader multi-case (MRMC) comparative effectiveness study details.
Standalone performance details.
Type of ground truth used.
Sample size for the training set.
How the ground truth for the training set was established.

This document focuses on technical and safety comparisons to predicate devices, not on clinical performance studies.

Dear Thomas Padula:

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. 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}------------------------------------------------

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

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

Comparison in Detail(s):

Note 1:

For red light irradiation mode and blue light irradiation mode, the subject device can be substantially equivalent to predicate device K171821, which was defined as primary predicate device.

For Red light combined with Infrared light, it can be substantially equivalent to predicate device K162489.

Note 2:

Even though there is a console weight difference between the subject device and predicate devices; they all are portable medical devices and comply with IEC60601-1 testing. Therefore, such a minor difference would not affect safety and effectiveness.

Note 3 (LED Wavelengths; Power density):

For LED wavelength:

Although there is a Minor difference of the LED wavelengths between the subject and predicate devices due to deviation tolerance of LED wavelength, they all belong to the range of red, blue and infrared light wavelengths, and the device passed the testing according to IEC60601-2-57, so such minor difference on wavelength would not affect safety or effectiveness.

For LED Power density:

{8}------------------------------------------------

There is only minor difference of the power density between the subject and predicate devices; and the device passed the testing according to IEC60601-2-57, so such a minor deviation would not affect safety and effectiveness.

Note 4

Even though there is a difference for the material between the subject device and the predicate device, its material complies with ISO10993-5 and ISO10993-10.

(7) PERFORMANCE STANDARDS APPLIED:

A series of studies were completed to demonstrate the substantial equivalence of TheraFace LED to the predicate device. All testing was conducted in accordance with and in conformance to applicable device regulations and guidance. Results of all testing demonstrate the device is non-toxic, is comparable to other currently marketed devices and is substantially equivalent to legally marketed predicates and included:
