Patients with cheilitis who have already developed crusts are in the process of healing, and they must not tear off the crusts with their hands, as this can lead to infection and worsen the condition. It is advisable for patients to keep their lips moist through methods such as local moist compresses. They can also apply mild, non-irritating lip balms. In daily life, patients should avoid licking or biting their lips and maintain a proper local temperature. It is important to avoid external stimuli such as spicy foods, sun exposure, or cold, all of which can trigger recurrent cheilitis or exacerbate the condition. Patients can also apply erythromycin eye ointment to promote local healing. (Please follow medical advice when using medications.)
