There is substantial heterogeneity in specifications of commercially available red and blue light-emitting diode (LED) masks for at-home acne treatment

This study was a market review of currently available at-home red and/or blue light-emitting diode devices for the treatment of acne. The specifications of currently available products (such as wavelength of light and fluence of devices) were mostly in line with specifications of devices that have been shown to be effective in treating acne in randomized controlled trials. This supplemental data includes the methods for this study, as well as the statistical analysis showing that there is no correlation between device price and device irradiance or fluence (power).

本研究旨在对目前市场上可用的家用红光和/或蓝光发光二极管设备进行市场综述，以治疗痤疮。目前可获取产品的规格（如光的波长和设备的辐射强度）大多符合在随机对照试验中已被证实有效治疗痤疮的设备规格。补充数据中包含了本研究的方法，以及统计分析显示设备价格与设备辐射强度或辐射量（功率）之间不存在相关性。
