Skin

The skin is the largest organ of the human body. Its size (about 20 square feet in an average sized adult) and external location make it susceptible to a wide variety of diseases, disorders, discolorations, and growths, as well as to damage from the environment and the aging process. The severity and appearance of skin problems vary considerably. The skin is one of the most vulnerable organs of the body. Though seldom life threatening, skin disorders can be uncomfortable and may cause chronic disabilities. In addition, because the skin is so visible, skin disorders can lead to psychological stress.
