LED masks have made a significant impact on the beauty care sector. These products use low level light therapy to treat damaged skin and encourage skin regeneration. However, there are no specific safety standards for LED masks. Therefore, consumers may incur risks, such as skin damage and eye burns. In this study, selected LED masks were investigated based on their number of LED modules and wavelength bands (blue, yellow, and red light). The irradiance and radiance were measured according to the measurement criteria of IEC62471, which is an international standard for photobiological safety. This standard was used to derive the results and to find the corresponding hazards to humans. The products use blue light, and the inclusion of a separate eye protection device was checked. The application of an automatic output blocking system was checked when the product is used for a particular period. This study aims to present a domestic photobiological safety standard management plan and guidelines for the use of LED masks according to the test results.
