How light changes your skin
Red and near-infrared light reach the mitochondria inside your skin cells - the part of the cell that produces ATP, the energy currency that powers everything from collagen synthesis to wound healing. Blue light, at 415nm, targets the bacteria that drive most breakouts. Different wavelengths do different work. The right mask gives you the ones that matter most for your skin, in the right combination, at the right intensity.
Before & After
Six-week treatment cycle, three 10-minute sessions per week. Results vary; individual experience may differ.
