At the age of thirty, the sk in begins to change and traces of the past years are drawn on the face. by collagen losses. What can we do to prevent this? Collagen is a very important protein for connecting tissue of up to 70% its mass. The human body is capable of producing at least 28 different types of collagen, but it is the collagen type I and III that is important for the health and beautiful appearance of the skin. It is crucial for maintaining skin elasticity, which is why any loss in collagen quantities affects the formation of wrinkles, loss of firmness and level skin moisturizing. 
The regenerative capacity of collagen decreases with age Collagen is a structural protein that is produced in special cells called fibroblasts, in the right skin layer. Fibroblasts also produce other structural elements i.e. elastin and hyaluronic acid. Both collagen formation and distribution take place in the right skin. Enzymes are responsible for decomposition, while collagen repairs and replaces damaged cells or builds new cell structures throughout our lives. As the years go by, the enzymes responsible for collagen distribution become more and more active, and the production of collagen by fibroblasts itself is decreasing. As a result, skin in the 80's shows four times more collagen damage than skin in the 21-30's.
Collagen peptides stimulate the skin to produce more collagen Over the last decade, there has been a significant increase in interest in what we can do to maintain a constant level of collagen in the skin, prevent its degradation and stimulate its synthesis in the aging skin. Studies have shown that collagen synthesis can be stimulated by peptides obtained from natural sources of collagen. Collagen peptides are an easily accessible protein. These proteins are not rapidly absorbed by the human digestive system, so only their enzymatic distribution to small peptides is a guarantee that it will be easily absorbed by the body. The collagen peptides in our collagen products are very easily digested and absorbed by the body. After consumption they are further decomposed into smaller peptides, which are "attracted" by fibroblasts.
Efficient test performance Several studies carried out in the last ten years on fibroblasts in the human body have shown that collagen peptides stimulate the body to produce its own collagen by activating fibroblasts. These studies have shown that the daily consumption of 2,5 to 10 g collagen peptides over a period of four to twelve weeks has a positive effect on the level of moisture, flexibility, smoothing of wrinkles and skin firmness.
