What is collagen?

Collagen is one of the most important building blocks in our skin. The fibrous structural protein consists of a chain of different amino acids – mainly proline, hydroxyproline and glycine. It makes up 30 percent of the total protein in the human body. Collagen is found not only in the skin, but also in joints, bones, teeth, ligaments and tendons. However, collagen production decreases with age. Find out here what functions the protein has in the body.

What is the function of collagen in the body?


Collagen keeps the skin firm and toned. It works closely with elastin, which gives the skin its flexibility. Collagen also strengthens cartilage structures and gives tendons and ligaments their ability to hold bones together. Beneath the skin’s surface, collagen fibres form a kind of basic framework that gives the skin a firm structure while keeping it flexible.



The body produces collagen itself. But as we age, it produces less and less of it. Oxidative stress also leads to a lack of collagen. There are then too many free radicals in the body, which destroy the collagen fibres. As a result, the skin loses its elasticity – it sags and wrinkles emerge. This process cannot be stopped completely. Every person ages naturally. However, if oxidative stress is the cause of the lack of collagen production, the skin can age prematurely. This is exactly what you can do about it!



If the body does not produce enough collagen on its own, you can also supply it from the outside. A good regular skincare routine, using creams and lotions that contain collagen, will slow down the ageing process. Also, add collagen to your diet! Of all foods, animal products are the best sources of collagen.

You can also take collagen in a dietary supplement, such as a drink. Ideally, you should also provide your body with other nutrients that promote normal skin maintenance, such as biotin or hyaluronic acid, or vitamin C, which contributes to normal collagen formation for normal skin function.
