Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The Dermis and Hypodermis. The dermis is a connective tissue layer, that contains collagen and elastin fibres, and fibroblasts, macrophages and adipocytes, as well as nerves, glands and hair follicles. The dermis is tough, and is the layer used to make leather. It can be divided into two regions: superficial region - (papillary dermis) the region around the dermal papillae, which makes up around 20% of the dermis. This layer contains loose connective tissue, and it has many capillaries.
