The skin is not only the largest organ in the body, it is also a mirror of the health of the body’s internal organs. In addition to protection of inner tissue structures, the skin helps in regulation of body temperature and elimination of metabolic waste products. Many diseases of the digestive, cardiovascular, and nervous systems, and hormonal imbalances and inflammatory conditions are reflected on the skin. With approximately 20 square feet of surface area, the skin is primarily taken care of for cosmetic appeal. Thousands of skin care products cater to beauty and health conscious consumers who hope to avoid acne, discoloration and signs of aging, as well as skin cancer. It is estimated that the global skin care products industry revenue will be $102.3 billion by 2018.
Psoriasis is an autoimmune, chronic inflammatory skin disease characterized by thickened, red skin with silvery scaled patches. These patches typically occur on the scalp, elbows, knees, and lower back. Although the exact cause of psoriasis is not clear, it is not a contagious disease. Psoriasis affects 2-3% of the world’s population, and men and women between the ages of 15 and 45 are equally affected.
