this mouthwash is said to brighten teeth with bluverite which is blue colorants that temporarily atick on the surface for a subtle brightening effect. it also contains hydrogen peroxide, which whitens over time.
hydrogen peroxide can whiten teeth but there isnt enough inn this product to do so. it can help maintain white teeth if used with more concentrated methods.
the smurfy cast fades in seconds to a tone that is flattering but doeasnt gleam.
