What is the outermost layer of the skin?

Epidermis
Dermis
Hypodermis
Stratum corneum

The correct answer is: Epidermis

The outermost layer of the skin is indeed the epidermis. The epidermis serves as the primary barrier between the body and the external environment, playing a crucial role in protecting against pathogens, UV radiation, and dehydration. It is composed of several layers of cells, with the most superficial layer being the stratum corneum. This layer contains dead skin cells that are continually shed and replaced, functioning as a robust shield for the underlying layers. Understanding the structure of the epidermis helps in various esthetic practices, such as the application of skin treatments and products. This layer is also vital for procedures like exfoliation, which targets the stratum corneum to promote healthy skin turnover. By recognizing the composition and protective functions of the epidermis, estheticians can better tailor their services to meet the needs of their clients.
