Dry, chapped lips often improve with a fragrance-free balm or plain white petroleum jelly. Cold weather, dry air, sun exposure and lip licking can make symptoms worse.
Simple lip-care routine
Apply a gentle moisturizer several times daily and before bed. Choose SPF 30 or higher lip protection outdoors. Avoid products that sting or contain menthol, camphor or strong flavourings.
When to seek help
See a dermatologist if symptoms continue after two to three weeks of gentle care.
