Bests & Worsts Reviews from Amazon

After reading the reviews on here, I knew I wanted to try it. However, I did not want to get my hopes up as I know how sometimes these things are gimmicks. I used the pen religiously, twice a day and it actually worked! now, my results were not a white as other reviewers, but they did get a lot lighter in 10 days' time. I noticed the difference in selfies and family photos where I would smile, I no longer had that ugly yellow tint. When I was a teen, I had a horrible dentist who ripped off my enamel and discolored my teeth after braces, these pens have actually given me more confidence to smile again.
