Skin has three layers: 1  The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. 2  The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. 3  The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
In many regions of hypodermis vestigial panniculus carnosus is present and is usually covered by panniculus adipose fatty layer. The function of elastin fibers found in the hypodermis layer is in giving elasticity to skin.t is the lowermost layer of our integumentary system. Though hypodermis is not part of the skin, it is very essential for anchoring the skin to the body. Though both dermis and hypodermis are derived from mesoderm, unlike dermis, this layer is not derived from dermatome region.
