Which is the outer layer of the skin that makes the body waterproof, gives it color, and to maintain hydration levels?

The stratum corneum is the outermost layer of the skin. It is a thick row of dead cells that contain keratin. Keratin is responsible for keeping the skin elastic and in preventing the underlying cells from drying out. The skin is called the Integumentary system of the body, it is responsible for protecting muscles, bones, and vital organs inside the body. It serves as a covering that is composed of two layers the Epidermis (outermost layer) and the Dermis (inner layer). They provide the necessary impulses for temperature control in the body through the different nerves and receptors.
