They are naked. Unlike the rest of your skin, your lips lack oil glands (called sebaceous glands). That’s a huge design flaw, honestly.
Without that natural oily shield, moisture evaporates like crazy. You’re basically walking around with two little sponges exposed to the wind.
The Tempting Lick Trap
You lick your lips for relief. It feels good for about two seconds. Then it backfires hard.
Saliva contains enzymes that break down food. Those same enzymes eat your lip skin for breakfast. The water in saliva evaporates, taking more moisture with it than was there before. You’ve just made the problem worse.
Fun fact: that tight, dry feeling after licking? That’s your lips screaming, “Why would you do this to me?”
