What is the primary function of the skin's dermis layer?

The primary function of the skin's dermis layer is support. The dermis is the thick, underlying layer of the skin that provides structural integrity and strength due to its dense network of collagen and elastin fibers. This layer also houses blood vessels, lymphatic vessels, hair follicles, and various glands, all of which contribute to its supportive role in maintaining the skin’s overall structure.

Moreover, the dermis acts as a cushion between the epidermis (the outer skin layer) and the underlying tissues, allowing it to absorb mechanical stress and preventing damage to the more vulnerable layers above. This support is critical for the skin to withstand stretching and pressure, making the dermis essential for maintaining the skin’s resilience and function.
