How does the dual-light system work, and what is the difference between the blue and red light modes?

The mouthpiece in this kit emits two wavelengths. The blue light is the primary driver: it photoactivates the whitening gel applied to your teeth, accelerating the surface reaction that loosens and lifts stain molecules (chromophores) from coffee, tea, red wine, or tobacco. The red light runs simultaneously as a complementary element intended to support a fresher oral environment during the session; it does not replace brushing, flossing, or professional hygiene. Both lights operate together in the same cycle — you do not need to switch modes manually. The combined approach mirrors the gel-plus-light principle used in professional settings, adapted for home use. Results vary based on your starting shade, the type of staining (external vs. internal), and how consistently you follow the instructions. This is a cosmetic brightening system, not a dental treatment, and it does not alter the natural structure of the tooth.
