Collagen is a type of protein. Fibrous in nature, it connects and supports other bodily tissues, such as skin, bone, tendons, muscles, and cartilage. Collagen can also be found in other parts of the body such as teeth, cornea, bone, lungs and other important internal organs.
By working with other proteins like elastin, collagen connects and supports body tissues. This combination of collagen and elastin is very important in many parts of the body, including, but not limited to, the lungs, bones, and tendons. Even the blood vessels rely on both collagen and elastin.
There are more than 25 types of collagens that naturally occur in the body.
Collagen makes up about 25% to 35% of the total amount of proteins in the body. Some people refer to collagen as the glue that holds the body together. Without it, the body would, quite literally, fall apart.
Collagen works with keratin to provide the skin with strength, flexibility, and resilience. As people age, however, collagen degradation occurs, leading to wrinkles.
Aging is related to collagen directly. When you age or become older, the collagen production becomes slower. Therefore, your skin begins to lose their elasticity.
From age 25 onwards, collagen production starts to slow down and you'll notice fine lines, wrinkles and other signs of aging.
