    Glossary Barrier Function

    skin's defense against environmental threats and moisture loss

    The barrier function refers to the skin's ability to act as a protective shield against environmental aggressors, such as pathogens, chemicals, and physical injuries. It involves the outermost layer of the skin, known as the stratum corneum, which maintains hydration and prevents the entry of harmful substances. This function is crucial for overall skin health and integrity, and its impairment can lead to conditions like eczema and increased susceptibility to infections.
