Dermis which is located between the hypodermis and the epidermis is a fibrous network of tissue which provides structure and flexibility to the skin. The dermal thickness varies between the averages of 2mm thickness. The most common structural component within the Dermis is the protein collagen which forms in a mesh-like framework which gives strength and flexibility to the skin.
Hypodermis is the outermost layer of the skin which provides a waterproof barrier and creates our skin tone. The hypodermis is called the deepest section of the skin which refers to the fat tissue below dermis, which insulate the body from the cold temperature and also helps body from shock absorption. They also store nutrients and energy. It is also thickest in palms of the hand and so of the feet.
