What are some home treatments for sore lips?

Home treatment for sore or chapped lips includes applying lip balm with petrolatum to lock in moisture and hydrating the body with increased water consumption, explains WebMD. An indoor humidifier can also help to treat sore lips by infiltrating the environment with moisture needed to repair dry lips and skin.

Try preventative measures such as avoiding oils or herbs such as eucalyptus, menthol or camphor that can dry and chap lips, recommends WebMD. Patients should also avoid biting and peeling lips as well as exfoliating the lip area to avoid irritating the skin. Harsh weather conditions also cause lips to become chapped and sore.
