The dermis is the second layer of the skin. It is 10 to 40 times thicker than the epidermis. Within the dermis are the appendages of the skin, the hair follicles, sebaceous glands, the two types of sweat glands ( eccrine and apocrine ), plus a complex capillary and nerve network. The dermis is made of 80 percent moisture, elastin fibers that supply elastic properties, and collagen fibers that provide a structural framework collagen represents about 70 percent of the dermal proteins and provides resistance, resilience, and traction.
