The epidermis is the outer layer of skin, comprised of translucent cells that produce keratin, a protein that protects you from potentially detrimental factors in the environment. This is the layer of skin that you can actually see and touch. The epidermis is also home to cells that produce melanin, which is the substance that gives skin its color.


The skin is composed of water, protein, and fat. The most commonly known proteins in the skin are collagen and keratin. Within the very outermost layer of skin, also known as the Stratum Corneum or skin barrier, skin cells are made up of proteins that can be easily damaged by harsh cleansing.


Skin is made up of three layers. The outermost is the epidermis. This consists mainly of cells called keratinocytes, made from the tough protein keratin (also the material in hair and nails).

Keratin (/ ˈ k ɛr ə t ɪ n /) is one of a family of fibrous structural proteins.It is the key structural material making up hair, nails, horns, claws, hooves, and the outer layer of human skin.Keratin is also the protein that protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents.


The skin shares a striking amount of transcripts (n=37) with esophagus, which is a tissue coated by squamous epithelia that has a similar epithelial structure and function as the skin. Many of these skin and esophagus group enriched genes belong to gene families that are important for normal squamous epithelial function.


Protein makes up many parts of the human body. Muscles, tissues, hair, skin, nails and eyes are all made up of protein, but amino acids, the building blocks of protein, are seen in all of the ...


The skin is the largest organ in the body, comprising about 15% of the body weight. The total skin surface of an adult ranges from 12 to 20 square feet. In terms of chemical composition, the skin is about 70% water, 25% protein and 2% lipids.


The health of our joints relies on cartilage made of type 2 collagen, which is why it’s beneficial for preventing age-associated joint pain or various arthritis symptoms. Type 3/Type III: Type 3 collagen is made of reticular fibers and a major component of the extracellular matrix that makes up our organs and skin. It’s usually found with ...
