The layer of the skin directly under the epidermis is called?

The layer of the skin directly under the epidermis is known as the dermis. This layer plays a crucial role in supporting and nourishing the epidermis, containing essential structures such as blood vessels, nerve endings, hair follicles, and various glands, including sebaceous (oil) and sweat glands. The dermis is also responsible for the skin's elasticity and strength due to the presence of collagen and elastin fibers.

Understanding the function of the dermis is vital for anyone studying skin care, as it is involved in vital processes such as thermoregulation and sensation. The subcutaneous layer, which lies beneath the dermis, serves as a cushion for underlying tissues and helps with the insulation and storage of fat, while the epidermis is the outermost layer that provides a barrier against environmental threats.
