The epidermis, the outermost layer of the skin, is composed of multiple layers, each with distinct characteristics and functions. From the most superficial to the deepest, these layers include the stratum corneum, stratum lucidum, stratum granulosum, and stratum basale. The stratum corneum is the outermost barrier of the skin, providing protection against external elements and water loss. The stratum lucidum, found only in thick skin like the palms and soles, is a thin layer that helps resist friction. The stratum granulosum contains cells that produce keratin, a protein that strengthens the skin. Finally, the stratum basale, the deepest layer of the epidermis, is responsible for cell renewal and growth.
