Think about it… :Think about it… Your skin is the largest organ in your body! It weighs approximately 8 pounds and covers a surface area of 22 square feet. You have about 300 million skin cells, and every minute you shed up to 40,000 of them. The photo in the last slide was of a cat scratch on the skin. Scratches generally heal and the dead skin is shed so they disappear.
