Lip balm can soothe chapped lips, but some people may be allergic to its ingredients. For those few, the products can sting instead of soothe. Dermatologists recommend looking out for flavorings, preservatives and fragrances in popular lip balms because they can cause allergic reactions. Other ways to soothe dry lips include covering the mouth with a scarf, drinking water and avoiding licking your lips too often. If your lips are still dry after trying lip balm, consider seeing a dermatologist to learn more.
