What is the normal water content of the skin?

1. 5-10%

2. 10-15%

3. 15-20%

4. 20-25%

The correct answer is: 10-15%

The normal water content of the skin is typically around 10-15%. This range reflects the balance that the skin maintains as it acts as a barrier to minimize water loss while also facilitating some degree of moisture retention. The skin's water content is crucial for maintaining its elasticity, hydration, and overall integrity. Too little water can lead to dry, cracking skin, while excessive water may indicate underlying health issues. Understanding skin hydration is essential in wound care and general dermatological practice, as treatments often aim to maintain or restore this optimal level of moisture for healing and infection prevention.
