The skin of an average human regenerates itself approximately every 27 days. Skin cells are continually recycling, with 30,000 to 40,000 skin cells dying every day. The entire top 18 to 23 layers of skin are made of dead cells.
The skin is the largest organ on the human body, weighing around 6 pounds on an average human. The skin is responsible for protecting the body from germs and infections and requires proper care to stay healthy. Thorough cleaning and moisturizing, limiting exposure to harsh sun rays and balanced nutrition are all required to keep skin healthy and protect its vitality.
