Review on Dale Audrey® White2Nite Professional Peppermint by Kristin Bell

I have used a whitening pen before and have been happy with the results. I ran out of this teeth whitening pen and picked up this pen to try. The main reason I bought this pen was to keep my teeth whiter. Omigosh, this formula is so subtle! It's too thin in my opinion. I always blot my teeth with a tissue to make sure they are as dry as possible before applying the whitening pen. Of course, saliva accumulates over time, especially around the lower gums just along the teeth. This formula is so runny it just won't last. I do not drink or eat anything for 30 minutes after application. I try my best to let the formula do its thing without interference. This is the worst teeth whitening pen I've ever tried. My teeth are turning slightly yellow-brown again. Worse shade than the one I started with. It also burns the gums. The formula is so thin that you can easily get on the gums. Hissing like I'm brushing my teeth and gums with hydrogen peroxide.
