What is Dry Skin, Exactly?
It’s easy to confuse dry skin with dehydrated skin, but they’re actually quite different.
Dry skin is a skin type, meaning it’s characterized by a chronic lack of sebum, or oil. This isn’t something that can be changed overnight; it’s just how your skin is.
Dehydrated skin, on the other hand, is a skin condition, which means it’s a temporary state often due to lifestyle factors and environmental influences. In short, your skin type relates to how much oil your skin produces, while your skin condition is about water levels in your skin.
Why Is Dry Skin More Likely to Be Dehydrated?
Since dry skin already lacks oil, it’s more vulnerable to dehydration. Here's why: sebum (oil) is essential for locking moisture into the skin. Without enough oil, your skin loses water more easily, making it both dry and dehydrated.
So if you’ve noticed that your skin feels particularly dry in certain conditions or seasons, this could be why.
