The skin is the largest organ in the body and plays an important role as a physical barrier to the environment. The structure of the skin allows for the inward and outward passage of water, electrolytes, and other substances while still protecting the body against environmental exposure. The skin also prevents loss of moisture, acts as a sensory organ, helps regulate body temperature, and synthesizes vitamin D3. It consists of three main layers as seen in figure 1 below: epidermis, dermis, and subcutis. The skin surface is constantly changing as the cells in the outer layers are shed and replaced by inner cells moving upwards toward surface [1].
