Dry vs. Dehydrated | The 101

The terms dry and dehydrated seem to be used interchangeably when in fact they are actually different.
Dry skin is a skin type, but dehydrated skin is a condition anyone can experience.
Dry skin has a lack of oil, or lipids. With dehydrated skin, there’s a lack of water in the stratum corneum, which is the top layer of the skin. You don’t need to have dry skin to have dehydrated skin. Oily and combination skin can be dehydrated as well, like my skin is currently.
