Today, collagen is a frequently used word, particularly in cosmetics and medicine.
It is a protein consisting of three protein fibres (triple spiral), which are composed of about 20 types of amino acids. It is the major protein of all connective tissues accounting for 25 – 30 % of all proteins in the human body and being a major structural element of bones, joints, muscles, tendons and all connective tissues – it forms e.g. about 75 % of the skin.
The task of collagen in the skin is to keep skin elasticity and to minimise formation of wrinkles, to keep the skin structure in the best possible condition, to renew continuously skin cells and to prevent dehydration.
Collagen content of the skin decreases yearly by 1.5 % after the 25th year of life and its synthesis stops after the 40th year. Thus, its replenishing is necessary and suitable for keeping a healthier and more elastic skin without wrinkles. The collagen decrease is accompanied by generation of wrinkles and cellulitis, the skin gets dry, nail and hair shine vanishes and the unavoidable aging process starts.
• intensive deep hydration
• skin elasticity increase
• smoothes small wrinkles
• slows down skin aging
• makes pigment blotches lighter
• efficient supplementing therapy of cellulitis treatment
• highly efficient against small dilated blood vessels and stretch marks
• causes no allergic reactions
• regenerates nails and hair
• has anti-coagulation features
• protects against blood coagulation
• includes glycine, which is important for healthy growth of muscles.
At present, we know at least 27 different collagen types. We use Roman numbers (I – XXVII) for their distinguishing.
Collagen type I is the most prevalent collagen and can be found e.g. in the skin, in tendons and bones. It represents 90 % of the collagens of human and generally animal bodies. It is often used in cosmetics. It stimulates production of own collagen in the human body and acts simultaneously as a building element it its synthesis.
Collagen type II is mostly located in cartilage.
Collagen type III can be found in the skin, in muscles and bones together with type I. It differs from type I due to its high amount of proteoglykanes and glycoproteins.
Collagen type IV is the collagen of basal membranes of epithelium cells. It forms neither fibriles, nor fibres and it participates in the net structures of the body. It includes little arginine.
Collagen type V can be found in interstitial spaces between muscle cells and on the edges of tissues and scars. It complements collagen type I.
The collagens I and II form the major structural element of the locomotive system.
