At the age of 30, the skin begins to change, and on the face, there are traces of the passing of the years. This is happening, among other things, by the collagen strands. What to do to prevent this?
Collagen is a very important protein for the connective tissue, which represents as much as 70% of 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 to health and the beautiful appearance of the skin.
It is crucial for maintaining the elasticity of the skin, which is why any loss of collagen affects the formation of wrinkles, the loss of firmness and the level of skin hydration.
The regenerative capacity of collagen is declining with age
Collagen is a structural protein that is formed in special cells called fibroblasts, in the layer of the dermis. Fibroblasts also produce other structural elements i.e. elastine and hyaluronic acid.
Both the formation and the distribution of collagen occur in the dermis. The distribution corresponds to enzymes, whereas collagen fixes and replaces damaged cells, or builds new cellular structures throughout our lives.
Over the years, enzymes that are responsible for collagen decomposition are becoming more active, and the production of collagen by fibroblasts is decreasing. As a result, the skin at the age of 80 shows four times more damaged collagen than the skin at the age of 21-30 years.
Collagen peptides stimulate the skin for larger collagen production
Over the past decade, interest has increased significantly in the topic of what we can do to maintain a steady level of collagen in the skin, prevent its degradation, and stimulate its synthesis in aging skin. Studies have shown that collagen synthesis can be stimulated by peptides derived from natural sources of collagen.
Collagen peptides are easily pro-consensible proteins. These proteins are not quickly absorbed by the human digestive system, which is why only their enzymatic distribution to small peptides is a guarantee that it will be easily assimilated by the body.
Collagen peptides in our collagen products are very easily digested and digested by the body. After ingestion, they are further decomposed into smaller peptides, which "attracted" are by fibroblasts.
Effective action by proven research
Several studies carried out over 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 proven that daily intake from 2,5 to 10 g of collagen peptides for a period of 4 to 12 weeks positively affects the level of moisturising, elasticity, smoothing of wrinkles and skin firmness.
