My derm suggested natural toothpaste to help my chronicly dry lips. They're really bad, and nothing helps them. He said that the artificial flavors and chemicals in commercial toothpaste can be really drying and irritating to your lips, especially if you have sensitive skin (which I do). I really like my strong fake minty flavor though, and natural toothpastes kind of scare me

Any suggestions? Does anyone use one that they really like?

Everything the light touches is my kingdom.
