The outermost layer of the epidermis, called the stratum corneum, acts as the major waterproof barrier for the skin. It is made up of sheets of dead cells that are packed with keratin, a protein that helps to create a tough, water-resistant barrier. This layer prevents water loss and protects the body from external elements like bacteria and viruses.
The epidermis is the outermost layer of the skin, and it plays a crucial role in protecting the body from the environment. The stratum corneum is responsible for the skin's ability to retain moisture and keep the body hydrated. This waterproof barrier also helps to protect the skin from damage caused by UV rays, chemicals, and other environmental hazards.
