Hismile V34 Colour Corrector Serum ($24)
Kim Kardashian has proclaimed her love for this “purple shampoo of teeth.” In a previous Instagram story, she told followers she was “obsessed” with the formula that “uses V34 color correcting technology to minimize unwanted yellow tones and staining.” She even showed the camera how “white and neutralized” her teeth looked after using the product. The brand notes that this serum works best when paired with a whitening treatment, but it could also be used on its own, along with toothpaste, to conceal yellow undertones.
