What is the function of the acid mantle on the skin?

To provide hydration
To serve as a protective barrier
To promote skin absorption
To facilitate exfoliation

The correct answer is: To serve as a protective barrier

The acid mantle serves as a protective barrier for the skin. It is a thin film of fatty acids and lactic acid that maintains the skin's pH level, typically around 4.5 to 5.5, which is slightly acidic. This acidity helps to prevent the growth of harmful bacteria and fungi, effectively protecting the skin from infections. Additionally, the acid mantle contributes to the overall health of the skin by reinforcing its barrier function, which is vital for retaining moisture and preventing transepidermal water loss. A well-functioning acid mantle is essential for skin resilience, helping to guard against environmental stressors and maintaining the skin’s integrity.
