Why Lips Get Chapped - Science Explained

Why do lips crack and peel so easily while the rest of your face survives

the same cold air? Lips are different skin. They’re thinner and

lose water faster. They also have fewer oil glands than most skin, so there’s less

natural protection. Cold air plus wind plus indoor heat usually mean low humidity so

moisture evaporates quickly. The trap: licking your lips feels helpful, but saliva evaporates

and can dry them out more. A simple fix is a thick balm or ointment

that seals in moisture especially before bed and before going outside. And don’t forget

SPF sun can damage lips even in winter. If you like quick body explanations
