Your skin is the largest organ in your body and covers about 20 square feet of surface area. It consists of three layers: the epidermis (the outer layer), the dermis (the middle layer), and the hypodermis (the inner layer). Your skin protects you from infections, injuries, UV rays, and temperature changes. It also regulates your body temperature, senses touch, pain, heat, and cold, and produces vitamin D. Your skin weighs around 17 pounds on average, which is about 15% of your total body weight.
