Skin is the largest organ of the human body. It exists as a barrier for the human body against the external environment, serving as the first line of defense, protecting the body from pathogenic microorganisms, chemicals, and physical factors. Skin also plays a role in thermoregulatory function and immunological processes. When assessing and managing skin conditions, practitioners must consider the physiological processes taking place within.

Skin plays a large factor in maintaining homeostasis of the human body, largely taking place in the stratum corneum (the most superficial layer of the epidermis which consists of 15 to 20 layers of corneocytes). When looking at the corneal layer microscopically, it resembles a brick wall. Corneocytes work as the thick bricks, cemented together with a fatty intracellular matrix as the cement. The health and ultimately the presentation of skin type is largely dependent on the integrity of the barrier, corneocytes, pH, and composition of superficial lipids.
