Crest Whitening Emulsions Leave-on Teeth Whitening Kit
An easy-to-use Crest teeth whitening gel with a spatula applicator, this delivers real lightening effects in a single day, no rinsing necessary. (Some users commented that it didn’t adhere to their teeth well, however.) “It painlessly whitened my sensitive teeth about two shades over one day — the difference is noticeable,” marveled GH Beauty Lab Senior Chemist Sabina Wizemann. “It stayed put, and after a minute or two, I didn’t even feel it on.”
Snow The Magic Strips Dissolving Teeth Whitening Strips
Gentle on teeth and on the palette, Snow’s refreshing teeth whitening strips dissolve in the mouth after about 15 minutes for no-fuss brightening. In GH Beauty Lab testing, users agreed they were easy to use, didn’t sensitize teeth or gums and felt refreshing, although one complained about the “sticky consistency” as they dissolved.
“Other whiteners I’ve used tasted really bad, but this minty flavor was great,” a tester commented. Another reported that it was “super convenient and less harsh than others, but still whitened my teeth.”
