It’s easy to assume that the words “dry” and “dehydrated” can be used interchangeably, but when it comes to skincare, they shouldn’t be. Both may result in your skin feeling, well, dry, but are caused by different factors and therefore, require different ingredients and skincare products to help your complexion bounce back. If you’ve ever gotten frustrated because your moisturizer or hydrating serum didn’t seem to be yielding the results you were seeking, it may be due to improperly diagnosing whether your skin is dry or just dehydrated.
