What is the protective barrier of lipids and secretions on the skin's surface called?

The protective barrier of lipids and secretions on the skin's surface is known as the acid mantle. This thin film is primarily composed of sebum (oily secretions from sebaceous glands) and sweat, which work together to create an optimal environment for the skin's health. The acid mantle plays a crucial role in protecting the skin from pathogens, pollutants, and environmental damage while preventing moisture loss.

Maintaining the integrity of the acid mantle is vital for overall skin health, as it helps to balance the skin's pH, supporting beneficial bacteria while hindering the growth of harmful microorganisms. When the acid mantle is compromised, it can lead to issues such as dryness, irritation, and sensitivity, highlighting the importance of this barrier in skin care and protection.

Other terms related to skin health, such as the hydrolipidic film, skin barrier, and dermal layer, refer to different components or layers of the skin and do not specifically denote the protective function associated with the acid mantle.
