I love Chapstick Flava Craze Blue Crazeberry It's been my favorite for years. The only place I can find it is a Walgreen's. So, each time I'm there, I buy 2 or 3. I have a drawer full of them. My husband teases me that I can't walk more than ten feet in the house without there being a Chapstick.
Aquaphor by Eucerin. Available at drugstores, sold as a "healing ointment," but I have been using it as a lipbalm for years, as reccommended by my dermatologist. It is inexpensive, flavorless, and long-lasting. I have tried Le Mer, Kiehl's, and others, and this one is just way better.
And, it also works on chapped nasal passages when you have a cold!
