The Smileactives whitening pen appears to be a great product and is very easy to use. I like using it after brushing my teeth with Smile Actives toothpaste for better results. It’s a convenient way to add an extra step to the whitening routine, and so far, it appears to work well.
I’m going to continue using it for a few weeks to see the full results, but based on my experience so far, I’m happy with the product.

The toothpaste works! The gel pen is too strong for me and burns my mouth .

The pen seems to be working well. Just started using it so no real results to report yet.
