What is the role of the acid mantle in skin physiology?

Protection against UV rays
Maintaining skin hydration
Barrier against bacteria
Regulating temperature

The correct answer is: Barrier against bacteria

The acid mantle plays a crucial role as a barrier against bacteria. This thin film of fatty acids and lactic acid on the skin’s surface creates an environment that is slightly acidic, which helps to inhibit the growth of harmful microbes. By maintaining a low pH, the acid mantle protects the skin from bacterial invasion and other pathogens that can lead to infections and irritations. This barrier function is essential for overall skin health and integrity, helping to keep the skin balanced and functioning properly. In contrast, while aspects like hydration and UV protection are important for skin health, they are not the primary function of the acid mantle.
