Which of the following is a potential cause of skin dehydration?

Excessive alcohol consumption is a potential cause of skin dehydration because alcohol acts as a diuretic, promoting increased urination and leading to a loss of fluids. This can result in the skin becoming dry, flaky, and lacking in moisture, as the body may not adequately retain hydration levels. When evaluating lifestyle choices, it is crucial to recognize that substances like alcohol can significantly impact skin health by disrupting its natural moisture balance.

In contrast, regular exercise typically promotes better circulation and oxygenation of the skin, which can contribute to a healthy appearance, while hydrating skincare products are designed to replenish moisture and protect the skin barrier. A healthy diet further supports overall skin health by providing essential nutrients and hydration. These lifestyle factors generally contribute to maintaining skin moisture rather than causing dehydration.
