Review on 😁 Crest 3D White Professional Effects Whitestrips: Advanced Teeth Whitening Kit by Kristina Perez

I don't know if I hate it but I can't tell the difference. I've been using it for its intended purpose since I received it on April 27, 2017. I also use Crest 2-Step Whitening Toothpaste. I was very happy to start this because I recently quit smoking. I wasn't expecting a pearly white result, but I'd appreciate a can of shades. Crest claims that stains take years to remove. I saw great reviews for this product, it might work for you but not for me. I won't be buying another box of these. The reason I gave it 2 stars is because I didn't feel any sensitivity while using this product. I'm sure this is a bonus for some people.
