Detailed answer

Dehydration diminishes the skin's ability to retain moisture, leading to a weakened moisture barrier. This can result in increased dryness, wrinkles, and dullness. When the skin lacks proper hydration, it becomes less supple and more prone to fine lines and wrinkles. Dehydrated skin also has a slower cell turnover rate, which can make the skin appear rough and uneven. Additionally, dehydration can exacerbate existing skin conditions, such as eczema or acne. Therefore, maintaining proper hydration is crucial for preserving the youthfulness and health of the skin.
