Active Wow Teeth Whitening Charcoal Powder
I am always looking for ways to have a movie-star-glowing grin, so I was excited to find this popular Active Wow Teeth Whitening Charcoal Powder ($25). It's the No. 1 bestselling option on Amazon. I decided to put the product to the test myself.
Wondering how charcoal works? The brand explains it best. "Derived from the highest-quality coconut sources, Active Wow's activated charcoal formula is safe to use for whitening your teeth, while being easy on your gums. Active Wow naturally whitens your teeth, not through harsh dental-grade whitening peroxides, but through the power of activated charcoal, nature's best purifiers, and detoxifiers."
