Absolutely loved the Charcoal plus Whitening variant. Firstly, the packaging is super cute, from the design and texture of the carton to the sleek and modern tube. Also a person who loses the lids and caps to their products I truly appreciate the attached cap. The most impressive thing about this variant was that I could see the whitening effect from day 1 and it has only gotten better with regular use. I also loved the longlasting freshness that my mouth had, even after meals my teeth still had that clean-feeling slip to them which I love. I also loved that although this range is sugar free, Charcoal plus Whitening still manages to have a sweet taste while having that fresh iciness that we love.
