Finally a natural teeth whitener
There are soo many teeth whitening products out there, and their ingredients are sketchy to say the least. I LOVE how transparent Keeko are with their ingredients, they add in additions to enhance the experience and nourish your body too which is such a nice touch. I am loving this whitening pen so far - I've been using it for around a week with already noticeable improvements (WOW!) and I can't wait for further results!
