What’s the Difference between Dry Skin and Dehydrated Skin?
Many people confuse the two. They’re not the same thing and it’s helpful to understand the difference in order to advance your skin health. For the answer to that vexing questing, as I most often do, I turned to the experts on the Paula’s Choice Research Team for insights. There’s a superb piece on the Paula’s Choice site titled, What is Dehydrated Skin & How to Choose the Best Products. Here is an excerpt:
Dehydrated skin often looks and feels like dry skin all over your face, but there's a major difference between the two: dehydrated skin is usually a temporary concern (with various surprising causes) and dry skin typically doesn't change over time. If you have dehydrated skin, your skin may also produce a normal or even excessive amount of oil on its surface.
"Dehydrated skin" is something we’re asked about frequently. It seems there’s a lot of confusion about what this skin concern is about. A major part of the confusion is that the term "dehydrated skin" is often used interchangeably with "dry skin" or "combination skin" but they are not the same! Dehydrated skin can occur in all skin types and is not exclusive to those with dry skin or combination skin.
The Difference Between Dry Skin and Dehydrated Skin
Having classically dry skin is easy to recognize. Dry skin frequently feels tight and dry, with no oil anywhere to be seen. This situation rarely fluctuates; skin feels dry all year long. The dryness might get worse depending on the climate, season, or activity, but regardless of those things, without great skin care products, the uncomfortable dry, tight feeling will persist.
As mentioned above, dehydrated skin can look and feel similar, but there’s a major difference: Dehydrated skin tends to come and go, it does not persist.
