The subject of this question is Biology.
The epidermis is the outermost layer of the skin and contains keratin and melanin. It is composed of several layers including the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum (when present), and stratum corneum.
These layers of the epidermis produce melanin which is responsible for giving the skin its color, and keratin which forms a protective, waterproof layer on the surface of the skin.
