Which is the outermost layer of the skin?

Dermis
Cuticle
Subcutaneous
Epidermis

The correct answer is: Dermis

The outermost layer of the skin is called the epidermis, not the dermis, cuticle, or subcutaneous layer. The dermis is the layer located beneath the epidermis, so it cannot be the outermost layer. The cuticle is a protective layer found in plants and insects, not in the human skin. The subcutaneous layer is the deepest layer of the skin and is mainly composed of fat tissue, so it is also not the outermost layer. Only the epidermis, with its tough and waterproof structure, serves as the protective barrier between our bodies and the environment. Therefore, the epidermis is the outermost layer of the skin.
