Hard Water Contains Dissolved Minerals
If you live in a hard water area, your tap water contains extra minerals such as calcium and magnesium. They won't do you any harm, but they can affect how comfortable your skin feels once you've dried your face.
When the water dries, tiny traces of those minerals stay behind. You usually can't see them, but a lot of people notice that their skin feels tight and itchy right after washing.
