The cells of the stratum corneum are held together by an overlapping mechanism and with proteins that serve as a binding "glue". The stratum corneum serves an important barrier function by keeping molecules from passing into and out of the skin, thus protecting the lower layers of skin. Disorders such as atopic dermatitis arise when this barrier function does not work properly.
