A brighter smile and healthier skin

It's a mouthwash! It's a cancer preventer! Into the large file of information on ingredients in normal everyday products that have surprising health benefits comes research that sanquinarine, an ingredient in toothpaste and mouthwash, can help prevent skin cancer. Now, if it would do that while it was also cleaning your teeth, that would be something, but apparently you actually have to apply it to your skin. Does this mean we'll soon be heading to the beach with a fresh coating of Colgate on our noses instead of zinc oxide? At least we'll smell minty fresh.
