The primary function of the stratum corneum is to provide protection against environmental damage. This outermost layer of the epidermis is composed of dead skin cells that form a barrier, effectively shielding the underlying tissues from various environmental stressors such as UV radiation, pathogens, and pollutants. Its structure, rich in keratin and lipids, helps to reduce water loss while preventing external agents from penetrating the skin, making it crucial for maintaining skin hydration and overall integrity.

Other functions, such as cell regeneration or production of melanin, occur in different layers of the skin, while absorption of nutrients is not a primary role of the stratum corneum. Instead, the absorption of substances primarily takes place through the living layers of the epidermis or the dermis, where active cellular processes are occurring. The stratum corneum's main role is therefore firmly rooted in its protective capabilities.
