What should I do if my lips are chapped or cracked?

When lip erosion occurs, comprehensive treatment and care measures should be taken. 1. Treat the underlying cause of the erosion appropriately. For example, if caused by cold sores (herpes labialis), oral antiviral medications such as acyclovir may be prescribed along with topical application of appropriate creams. If due to allergic cheilitis, discontinue the allergenic substance and take antihistamines such as chlorpheniramine. 2. Supplement B-complex vitamins, especially vitamin B2, which helps promote lip health. 3. Maintain a balanced diet, ensure adequate hydration, and consume foods rich in riboflavin, such as whole grains and legumes. 4. Pay attention to oral hygiene—rinse the mouth promptly after meals to prevent bacterial growth from food residues. 5. Apply physical remedies to relieve symptoms, such as rinsing with mild saline solution or applying ice packs for cold compression, to reduce swelling and pain.
