What is referred to as the true skin in esthetics?

1. The epidermis

2. The dermis

3. The hypodermis

4. The stratum corneum

The correct answer is: The dermis

The term "true skin" refers specifically to the dermis, which lies beneath the outer layer of skin, known as the epidermis. The dermis is a vital part of the skin's anatomy, encompassing connective tissues, blood vessels, nerves, hair follicles, and various glands, such as sebaceous (oil) and sweat glands. This layer is essential for providing strength, elasticity, and flexibility to the skin, largely due to the presence of collagen and elastin fibers. The dermis also plays a critical role in temperature regulation and sensation, as it houses sensory receptors that respond to touch, pressure, and pain. In contrast, the epidermis is the outermost layer of the skin and primarily serves as a protective barrier. The hypodermis, or subcutaneous layer, is beneath the dermis and consists mainly of fat and connective tissue, functioning as insulation and cushioning for the body. The stratum corneum is the outermost layer of the epidermis, composed of dead skin cells that help protect against environmental damage. Understanding these distinctions is crucial for estheticians when addressing skin health and care.
