Look for hydrating ingredients like beeswax, shea butter, vitamin E and almond, jojoba or coconut oils. Good old petroleum jelly (think Vaseline) works well too. If you have sensitive skin, use camphor based medicated lip balms sparingly. (They can be irritating.) Instead, opt for the camphor free A?sop Rosehip Seed Lip Treatment with shea butter ($15; 888 223 2750). But if you have hearty skin, try ChapStick Medicated lip balm ($1.69; at drugstores) with camphor and menthol.
