1 The epidermis is the epithelial tissue layer of skin. 2  Hair follicles, sebaceous glands, and sweat glands are epithelial invaginations from the epidermis. 3  The dermis is the connective tissue layer of skin.  Embedded within the dermis are hair follicles and sweat glands as well as blood vessels and sensory nerve endings.
Dermis. The dermis is the deepest vascular inner skin layer, and is responsible for providing the skin, its strength, and elasticity. This is because of the fibers of the collagen and elastin. The thickness varies, which is 0.3 mm (min) on the eyelids, and 3.0 mm (max) on the back. The regulation of the body temperature is also undertaken by the dermis. When the body is exposed to heat, blood vessels increase the blood flow to the skin, helping the heat to escape.
