Physical/Mechanical barrier
The skin is the organ that has two layers, the epidermis and the dermis. The epidermis is the outermost layer responsible for providing a waterproof barrier and the dermis is the layer beneath it that contains blood vessels and nerve endings.
The stratum corneum is the outermost layer of the epidermis and is avascular, meaning it lacks blood vessels. This layer is made up of dead skin cells that provide a protective barrier for the underlying layers of skin.
