How it Works The Natural WhiteSpa System starts with our Power Whitening Accelerator. Shining an intense beam of pure light filtered through over 12,000 optical fibers and 30 layers of coated optical glass, the Whitening Accelerator illuminates the teeth at a wavelength of 480 to 520 nanometers,proven to be the optimal range for tooth whitening. Harmful ulta-violet (UV) and infrared light is completely removed by the filtering system, leaving only a focused bean of cold-light in the blue cyan spectrum,which penetrates deep into the teeth,activating the Whitening Formula Gel to its optimal potency. Our proprietary formula is applied directly to the tooth surface and the Whitening Accelerator's intense cold-light activates the whitening gel to rapidly accelerate the whitening process. In just three,20-minute cycles,tooth discoloration from years of staining foods,coffee,tobacco,cola and red wine are eliminated leaving a beautiful,shiny-white smile.
