Show Notes

Red light devices promise a lot—but do they deliver? Wirecutter supervising editor Rory Evans demystifies the science behind them, shares her top picks, and explains who might want to think twice before trying one.

Correction: In this episode, we misstated that the irradiance, or power over an area, of red light devices is measured in megawatts per square centimeters. It is measured in milliwatts, not megawatts.
