I was skeptical at first, but I'm seeing results withing 2 weeks so i'm very happy about it. Great packaging and seems like a quality product. Will update soon.
I know about charcoal teeth whitening because I have used it before. It has a great way of cleaning and whitening your teeth. This product is excellent! Make sure to rinse well after you brush with it. Your teeth feel so soft and smooth afterwards. great for sensitive teeth like mine.
