Dehydration can have several negative effects on skin health. When the body is dehydrated, the skin can become dry, tight, and flaky. Dehydration can also lead to a decrease in skin elasticity, making it more prone to wrinkles and fine lines. Additionally, dehydrated skin may appear dull and lackluster, as proper hydration is essential for maintaining a healthy glow. It's important to stay well-hydrated to support overall skin health and maintain a youthful appearance.
