Chapped lip remedy
Presuming chapped, cracked lips are due to cold weather and not toothpaste, contact allergy from lipstick compound and lip care products, or medications you are taking.
First, stay hydrated and avoid licking you lips as this can leave lips drier. Use an oil-based emollient
cream, or a petrolatum or beeswax containing lip balm. Apply frequently. If severe, short term low potency steroid helps.
