Skin is the largest organ of the body, which acts as the first barrier against many harmful external factors. The skin has different layers which are discussed below:
The dermis is right below the epidermis and is composed of elements that are responsible for skin toughness and elasticity. These elements are:
1) Collagen fibers: This is the main skin component that causes skin toughness.
2) Elastin fibers: This protein is the main factor which gives elasticity and flexibility to the skin.
3) Ground substance (matrix): This is an amorphous material that holds a lot of water which is necessary for skin’s freshness and beauty.
Dermis also contains blood vessels and nerves. Blood vessels bring oxygen and nutrients to the skin.
