The Series 3 mask uses an additional 514 LEDs and 3 additional light wavelengths: blue (415nm), green (532nm) and yellow (590nm). New MyDose™ technology and app connectivity allow for fully customisable light therapy sessions. Every user has the ability to build and save a treatment protocol that is entirely their own, calibrated to their unique skin type, concerns and goals. You choose the wavelengths that match your skin concerns and we calculate your optimal dose, so you can be confident that each session delivers the correct, safe and clinically effective level of light for results.
