What outcome can result from improper hydration in the skin over time?

Improved complexion
Increased risk of dermatitis
Enhanced skin resilience
Decreased risk of aging

The correct answer is: Increased risk of dermatitis

Improper hydration in the skin can lead to an increased risk of dermatitis over time. Hydration is crucial for maintaining the skin's protective barrier, which helps prevent irritants, allergens, and pathogens from penetrating the skin. When the skin is not adequately hydrated, it can become dry, flaky, and more susceptible to inflammation and irritation. This can result in conditions such as dermatitis, which is characterized by redness, swelling, and itching. Maintaining proper hydration helps to keep the skin soft and supple, thereby reinforcing its barrier function and reducing the likelihood of dermatitis and other skin-related issues. In contrast, the other outcomes listed would typically not arise from improper hydration. For instance, improved complexion, enhanced skin resilience, and decreased risk of aging are all associated with adequate hydration rather than its absence. Proper hydration supports the skin's overall health and appearance, highlighting the importance of maintaining moisture balance for preventing skin problems.
