ELI5: Why does licking your lips when they are chapped give temporary relief but then they become more chapped than when you started?

Because you are removing the protective oils and physically irritation your lips each time. The result is that it gets your lips wet again (the instant relief) but then because that barrier is gone that water quickly vanished, and now you’re worse off than when you started (because you’ve sandpapered away that protective layer).
