The three layers of the skin are indeed the epidermis, the dermis, and the subcutaneous layer. The epidermis is the outermost layer, providing a protective barrier and containing cells that produce keratin, which helps in skin protection and water retention. Below the epidermis lies the dermis, which is much thicker and contains connective tissue, blood vessels, hair follicles, and glands. This layer plays a crucial role in sensation and thermoregulation due to its rich supply of nerve endings and blood vessels.

The subcutaneous layer, also known as the hypodermis, is the deepest layer of the skin, composed mainly of fat and connective tissue. This layer serves as insulation, helps maintain body temperature, and provides cushioning to protect underlying muscles and organs.

Understanding these layers is vital for a variety of practices in cosmetology, including skin care treatments, understanding skin conditions, and performing cosmetic procedures, as each layer has distinct functions and characteristics that can influence the health and appearance of the skin.
