Lip balm or beeswax provides the easiest solution to treat chapped and irritated skin around the lips. Madeline Vann, a health and medical writer at Everyday Health, explains that chapped lips usually stem from a few common causes: allergies, inflammatory skin disease and sun damage that is precancerous. In any case, lip balm relieves the skin around the lips when it becomes dry and irritated.
Vann also makes a few other suggestions regarding treating and preventing chapped lips, including drinking water to stay hydrated and using lip products with a sun protection factor. She explains what not to do, which includes licking the lips and exfoliating the lips. She also recommends avoiding antibiotic ointment, hydrocortisone, "natural" products and zinc oxide.
On WebMD, dermatologist Jennifer Linder, MD notes that people must seal in moisture and get extra hydration with beneficial oils to prevent chapped and irritated lips. She recommends products containing ingredients such as petroleum, castor seed oil, shea butter, sunflower seed oil and squalane. She also recommends products with ingredients like hyaluronic acid, sodium PCA, and glycerin to ensure the lips stay moist. Linder explains that licking the lips actually irritates them further since saliva dehydrates the skin after it dries.
