The primary function of the dermis layer of the skin is to provide structural support. The dermis is located beneath the epidermis and is made up of connective tissue that contains collagen and elastin fibers. These components give the skin its strength, elasticity, and resilience. The dermis also houses various structures, such as hair follicles, sweat glands, and blood vessels, which contribute to the skin's overall functionality and protection.

While other options, such as regulating body temperature and acting as a barrier against UV radiation, are important skin functions, they are primarily associated with different layers of the skin or additional processes. The epidermis, for instance, plays a significant role in barrier protection, including UV defense, while temperature regulation is largely managed through sweat glands and blood vessel dilation within the dermis. However, the fundamental role of providing structural support is a defining characteristic of the dermal layer itself.
