Why does licking your lips dry them out?

I've noticed that whenever my lips are dry I tend to lick them. And, it's something that I do whenever I get nervous as well. But, it just makes my lips feel more dry, especially if they are chapped already. Does anyone know why licking one's lips makes them even more dry?

I think it is like when you see a water droplet on your hand, you lick it off. You took away the moisture. And the same can be applied to your lips. When we lick our lips, we lick away the moisture, we don't add to it.

It the evaporation rate! When you have moisture on lips or on skin, if you don't put anything on top to lock the moisture into the skin/ lip. The moisture would evaporate into the air, and not only that, it would bring the moisture already in your skin/ lips back into the air, therefore, you feel dry. That's why they say you can use a cloth mask on your face till it's totally dry, because it would be worse than not doing a facial mask at all.
