Dear Na Wu:

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.

## 510(k)s-Section 6. 510(k) Summary

## V. Device Description

The Diode Laser Hair Removal device models LHR-V8S-810, LHR-V8-810, LHR-V4S-810, and LHR-V4-810 emit pulses of invisible infrared laser light of 810mm wavelength that penetrates into the skin and is selectively absorbed by melanin in the hair follicles. This creates a localized thermal effect that disrupts hair growth from the hair follicles. The device contains a sensor that detects contact with the skin so that the device will only emit the infrared laser pulses when the sensor is in contact with the skin. The device also includes a skin cooling feature and the device is powered by an external AC/DC power adaptor.

## VI. Indications for Use

Diode Laser Hair Removal is an over-the-counter device intended for adjunctive use with shaving for hair removal sustained with periodic treatments. SILKPRO is also intended for permanent reduction in hair regrowth defined as a long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.
