Even though people use the terms dehydration and dryness interchangeably when it comes to dry skin, they are not the same thing. Dryness comes from changes in hormones, aging, medications or extreme weather, among other things. Dehydration has to do with what is going on inside the body in terms of keeping the body hydrated with enough water and other fluids. Waste removal and replenishing vital organs requires proper hydration to function, including the biggest organ of all, the skin. So while dehydration can lead to dry skin, they are not the same thing. In order to have smooth and youthful skin, both must be conquered.
