The skin is the body’s largest organ and is made up of water, proteins, lipids and different minerals and chemicals. Its job is to protect the body from infections and germs. The skin regenerates itself about every 27 days. The stratum corneum is the outer layer of dead skin cells that used to exist in the epidermis. The epidermis is the outer layer of the skin and is also the thinnest layer. It is responsible for protecting the body from the environment.
