Despite urban myths about addictive chemicals in lip moisturizers, the Mayo Clinic in Rochester, Minnesota, says that repeatedly slathering your kisser with a favorite remedy is a healthy habit. In fact, this absorbent and sensitive part of the epidermis lacks oil glands, and saliva only dries lips out. So quality salve is a must to prevent cracking and flaking. Look for one packed with cocoa butter, calendula, rosemary extract, vitamin E, and jojoba oil, says Kim Erickson, author of Drop-Dead Gorgeous (McGraw-Hill, 2006). And don't forget to choose one with SPF 15 or 30. A few to try: Desert Essence's Lip Rescue, Jason's Lips Bee Better, and Eco Lips' Lip Care Kit, with six balms made with more than 70 percent certified-organic ingredients.
