Sarveiskerrokselle

Sarveiskerrokselle, also known as the stratum corneum, is the outermost layer of the epidermis, the protective outer skin. It is composed of flattened, dead skin cells called corneocytes, which are filled with keratin. These corneocytes are arranged in layers and are held together by a lipid matrix. The stratum corneum acts as a barrier, protecting the body from environmental insults such as pathogens, dehydration, and UV radiation. It also plays a role in sensory perception, as nerve endings are located in the underlying epidermal layers. The thickness of the stratum corneum varies across the body, being thickest on the palms of the hands and soles of the feet, and thinnest on the eyelids. This layer is constantly shedding and regenerating, with new cells migrating from the deeper layers of the epidermis. This continuous process of renewal is crucial for maintaining skin health and its protective functions. Conditions affecting the stratum corneum can lead to various skin issues, including dryness, scaling, and increased susceptibility to infection.
