What is the name of the inner layer of the skin?

The inner layer of the skin is known as the dermis. This layer is located beneath the epidermis and is critical for supporting the skin's structure and function. The dermis contains connective tissue, hair follicles, sweat glands, and blood vessels, which are essential for nourishment and thermoregulation of the skin. It also plays a key role in sensation as it houses nerve endings that react to touch, pressure, and temperature.

In contrast, the epidermis is the outermost layer of skin, primarily responsible for providing a protective barrier. The stratum corneum is a specific part of the epidermis made up of dead skin cells that have been shed and are continuously replaced. The subcutis, or hypodermis, lies below the dermis and is primarily composed of fat and connective tissues, providing insulation and cushioning for the body. Understanding these layers is vital for a nail technician, especially when considering how to care for nails and surrounding skin.
