Which skin function is essential for maintaining hydration?

Barrier function
Thermoregulation
Sensation
Excretion

The correct answer is: Barrier function

The barrier function of the skin is crucial for maintaining hydration. This function primarily involves the stratum corneum, the outermost layer of the skin, which acts as a protective shield. It prevents transepidermal water loss by forming a barrier that retains moisture within the skin and protects it from external factors such as environmental pollutants and pathogens. A compromised barrier can lead to increased water loss, resulting in dryness and vulnerabilities to irritants and infections. Thus, the integrity of the barrier function is vital for retaining hydration and maintaining skin health.
