Star-Sparkling Brightening Sonic Toothbrush is a blue light whitening toothbrush that uses nano blue light whitening technology. The high-intensity blue light promotes a rapid reaction between the customed toothpaste and the surface pigments of the teeth, resulting in long-lasting whitening effects. The intensity of the blue light is adjustable, allowing users to select the appropriate level based on their personal preference. The whitening effect is extremely powerful, with a real whitening increase of 6 shades in just 10 days.
