Dehydrated skin primarily lacks what component?

Dehydrated skin primarily lacks water. This condition occurs when the skin does not have enough moisture to maintain its usual elasticity and suppleness. Dehydration can manifest as tightness, rough texture, and a dull appearance, which are signs that the skin is not retaining sufficient hydration.

While oil (lipids) is important for creating a barrier that prevents moisture loss, dehydrated skin specifically refers to a deficiency in water content, even when oil levels might be adequate or excessive. Vitamins and minerals contribute to overall skin health but are not directly tied to the state of hydration. Therefore, recognizing that dehydration is fundamentally a lack of water is essential for effective skincare treatments and recommendations.
