There are two main programs to follow—Blemish Repair, which uses a combination of blue light (415 nm), infrared, and red LED (630-830 nm) for eight minutes, and Better Aging, which uses just infrared and red LED for six minutes. It’s recommended to follow one program daily for eight weeks, switching to the four-minute Skin Sustain program afterward to maintain the best results. I also like that there are three settings—red light only (press the button once), blue light only (press twice), and red-and-blue light combo (press three times). It has a single 630-nm red light wavelength, and former WIRED reviewer Medea Giordano found it quite relaxing to use. With vibration and warmth therapy thrown in with the light, it feels like a full spa experience.
