The reticular dermis is the deeper and thicker layer of the dermis. It is composed of dense, irregular connective tissue, which provides strength and elasticity to the skin. This layer contains larger blood vessels, nerve fibers, and various skin appendages such as sweat glands, sebaceous glands, and hair follicles. The reticular dermis is also rich in collagen and elastin fibers, which are crucial for the skin's structural integrity.
