What effect does adequate hydration have on the skin?

Decreased elasticity
Improved texture
Increased pore size
Reduced moisture retention

The correct answer is: Improved texture

Adequate hydration has a significant impact on the skin, primarily leading to improved texture. When the body is well-hydrated, it helps maintain the skin's moisture balance, which is essential for its overall health and appearance. Hydrated skin appears smoother, plumper, and more resilient, as hydration aids in maintaining the skin barrier function and supporting cellular processes that promote skin regeneration. In contrast to the other effects mentioned, good hydration does not lead to decreased elasticity; instead, it helps maintain or improve elasticity by keeping the skin cells nourished. Additionally, while proper hydration does not increase pore size, it can help them appear smaller due to the overall improved texture of the skin. Reduced moisture retention is also contrary to the benefits of adequate hydration, as ensuring the skin is hydrated enhances its ability to retain moisture rather than diminish it. Therefore, the best description of the effect of adequate hydration on the skin is its contribution to improved texture.
