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

Description

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).
