Myths and facts about collagen

Collagen is an essential element skin. The last decades numerous of cosmetic products use collagen in order to enhance skin beauty. But what myths and truths are behind its use?


Collagen exists only in our skin.

Myth. Even though epidermis is composed mainly of collagen (75%), collagen can also be found almost all over the body (skin, joints, hair, tendons, and cartilages). It is one of the most common proteins. ιt is responsible for the stability and structure of the skin, while also for tissue support and elasticity. It consists of 20 different amino acids, mainly glycine, proline and hydroxyproline (50%).

It is the basic element of a young skin.

Fact. Collagen is produced in abundance when we are young, however, after the age of 25-30, there is a significant reduction in endogenous production. Reduction of collagen production, makes the skin brittle and less elastic, resulting in wrinkles.


All types of collagen are the same.

Myth. Not all types of collagen are the same. According to reports, there are over 28 types of collagen depending on the tissue (bone, skin, tendons, ligaments, cartilages etc.). There are several types of collagen in trade depending on their origins, such as type 1 collagen (marine collagen) or chicken or beef type 2 collagen.


Hydrolyzed collagen is superior to other collagen types.

Fact. Collagen is a very large molecule that can not be absorbed. For this reason, the most absorbable form of collagen is hydrolyzed collagen, which has a much lower molecular weight and is thus much more absorbable by the intestine cells.


Collagen only helps in the coherence and good appearance of the epidermis.

Myth. As collagen is a substance that exists in almost all tissues, collagen intake helps not only in the elasticity of skin but also benefits joints and cartilages. In particular, because it reduces stiffness and improves joint mobility, it improves pain and it is used for the treatment of rheumatoid arthritis and osteoarthritis, especially in injectable form.


Adding collagen to the epidermis does not increase endogenous collagen production.

Fact. The application of cosmetic products containing collagen, and especially in hydrolyzed form, help the skin regain its lost elasticity, but unfortunately does not increase endogenous collagen production.
