If you've tried teeth whitening strips and whitening toothpaste but are unhappy with the results, giving this color-correcting purple goo a try might be worth it.
I saw an ad yesterday for hismile's V34 color correcting formula that conceals stains on teeth, similar to how purple shampoo helps tone blonde hair for a brighter look. (If you have blonde hair like I do, then you know how necessary purple shampoo is to keep your hair brass-free!)
I haven't personally tried this yet, but I'm going to. I wanted to share this info with you ASAP though! The V34 Colour Corrector Serum is pretty affordable, too. Check it out here.
