Which sequence correctly identifies the layers of skin and fat from the outermost layer to the innermost layer?

The correct sequence that identifies the layers of skin and fat from the outermost to the innermost layer is Epidermis, Dermis, Subcutaneous.

The epidermis is the top layer of the skin and serves as the first line of defense against environmental factors. It is composed mainly of keratinized cells, which help protect the underlying layers and maintain hydration. The dermis lies just beneath the epidermis and is much thicker. It contains connective tissue, blood vessels, hair follicles, and glands, providing structural support and nourishment to the skin. Finally, the subcutaneous layer, also known as the hypodermis, is the deepest layer, consisting primarily of fat and connective tissue. This layer plays a crucial role in insulation, energy storage, and cushioning for underlying structures.

Understanding this layering is vital for cosmetology professionals, as it informs various procedures such as skin care treatments, hair removal techniques, and other services that may affect these layers.
