The bleaching process is carried out by a high-intensity cold light lamp: a powerful accelerator when working together with Beyond gel. Blue light with a wavelength of 480-520 nanometers passes through 12,000 optical fibers, eliminating harmful UV and IR radiation. Protection against overheating and irradiation makes whitening absolutely safe. Improvements in the radiation and filtration system reduce the time of the procedure. Used for photo bleaching by an average of 8 tones.
