Skin is an important organ. Not only is it the largest organ of the human body, it also protects the body in a number of ways, providing innate immunity through its function as a physical barrier against pathogenic microbial invasion, controlling fluid loss and regulating body temperature (Sibbald et al, 2003). The stratum corneum is the outermost of the five layers of the epidermis and is largely responsible for the skin’s vital barrier function. If the stratum corneum breaks down, the barrier function of the skin can become impaired.
