When your body lacks enough water, your skin can appear:
-
Dull and less radiant
-
Dry, rough, or flaky
-
Tighter or less plump (due to reduced elasticity)
-
More wrinkled or lined, especially around the eyes and mouth
Unlike dry skin (which lacks oil), dehydrated skin lacks water, and this can emphasize fine lines and make your complexion appear tired or aged.
The good news? Rehydrating from the inside out—by drinking enough water and using hydrating skincare—can restore a more youthful, glowing appearance.
