Collagen is the most important structural component of the skin.
Collagen peptides are hydrolyzed collagen protein, i.e. broken down small fragments of the entire collagen protein.
Bioactive collagen peptides can be actively incorporated into the connective tissue of the skin and thus contribute to reducing the depth of wrinkles and improving skin elasticity. Another important function is that the peptides can stimulate certain skin cells (fibroblasts) to produce more of the body's own collagen and, in the long term, improve the appearance of the skin and regenerate damaged structures in the skin and connective tissue.
It is important that these effects can only be triggered by collagen peptides, but not by the native collagen protein. Absorbing all the protein is very difficult due to its size. Absorption through creams or lotions that can be applied externally to the skin does not have this effect.
