The dermis is the thick layer of skin located beneath the outer layer called the epidermis. It plays a crucial role in providing strength and elasticity to the skin, thanks to its rich composition of collagen and elastin fibers. This layer also contains blood vessels, which supply nutrients and oxygen, as well as nerve endings that help us feel sensations like touch and temperature. In addition to these functions, the dermis houses important structures such as hair follicles, sweat glands, and sebaceous glands. These components work together to regulate body temperature and keep the skin moisturized. Overall, the dermis is essential for maintaining healthy skin and protecting our bodies.
