High-intensity cold-light activates the Whitening Gel, a special whitening formula that contains hydrogen peroxide (H2O2) and 20 nanometer silicon dioxide (SiO2), along with several other special ingredients.
The one-hour procedure oxidizes the pigmentation of 16 or more teeth through to the dentin layer, restoring them to a beautiful, natural white.
We uses the most advanced technology to produce a cold light emitting diode with a wavelength of 465-467.5 nanometers.
The light is filtered through over 12,000 fibers, reaching a total length of one mile, and finally through one optical-lenses.
