These two terms are often used interchangeably– but they’re not the same thing.
Dehydration is a lack of water, and dryness is a lack of lipids.
If your skin doesn’t hold its shape and takes a few moments to bounce back, it’s likely dehydrated.
Dry skin is often more uncomfortable and can come with roughness and flakes.
Both are tough on your skin, accelerate aging, and lead to inflammation.
Consistently dehydrated skin could be a sign your body needs more fluids and minerals like potassium, sodium, and magnesium (to help water get into your cells). Dry skin might mean you’re not getting enough fats in your diet (think tallow, butter, eggs, full-fat dairy).
As you support your skin from within, saturated skincare can nourish topically.
Fatty acids soften and lubricate, while naturally occurring vitamins and minerals rebuild the moisture barrier and prevent water loss.
