## Definition

the outermost layer of the skin. It is the thin, protective layer that you can see and touch.

For teachers: the outermost of the three layers of the skin, consisting of stratified squamous epithelium. It provides a waterproof barrier and protects against environmental damage.

## Examples

- The epidermis is the thin layer on the surface of your skin.

- The epidermis is constantly renewing itself through a process of cell division and migration, eventually shedding dead skin cells to maintain a healthy barrier against pathogens.
