👉 Epiderm is a term used in medical and scientific contexts to describe the outermost layer of skin. It includes the top layer, called the stratum corneum, which protects the skin from external elements such as UV rays, dust, and pollution. The epidermis also contains hair follicles, sweat glands, and other structures that are responsible for maintaining a healthy, hydrated skin environment. Epiderm is an essential part of the human body's overall defense against infection and disease.
