Our largest organ, the skin forms a wall against the outside world. It helps keep water from escaping and stops disease-causing microorganisms, ultraviolet light, and noxious chemicals from penetrating deeper. The skin’s oils play an essential role in that barrier function. Some lipids discourage colonization with fungi and bacteria. In addition, dry skin cracks more easily, which not only hurts but also creates holes in the wall. In a nutshell, dry Skin becomes inflamed and infected very easily. There are, however, things we can do to keep skin moist.
