Glossary Skin Barrier Function

protects against external threats and prevents water loss

The Skin Barrier Function, also known as the Epidermal Barrier Function, refers to the skin's ability to protect the body from external threats like pathogens, chemicals, and physical injuries, while also preventing excessive water loss. This function is primarily carried out by the outermost layer of the skin, the stratum corneum, which consists of tightly packed dead skin cells and lipids that form a protective barrier.
