The three layers of the skin are indeed the Epidermis, Dermis, and Subcutaneous. This arrangement reflects the structure of the skin, with each layer having distinct characteristics and functions.

The Epidermis is the outermost layer and serves as a protective barrier against environmental factors, pathogens, and water loss. It is composed mainly of keratinocytes and varies in thickness depending on the area of the body.

The Dermis lies beneath the Epidermis and is significantly thicker. It provides structural support and elasticity due to the presence of collagen and elastin fibers. This layer contains blood vessels, nerve endings, hair follicles, and glands (both sebaceous and sweat), playing a crucial role in thermoregulation and sensation.

The Subcutaneous layer, also known as the hypodermis, lies beneath the Dermis. It consists mainly of adipose tissue and connective tissue, serving as insulation and energy storage, as well as anchoring the skin to underlying structures such as muscles and bones.

Understanding the composition and function of these layers is essential for estheticians in providing effective skin care treatments, as it underpins how different products and treatments interact with the skin.
