Superimposition of many of these triple helices produces fibrils of collagen that are stabilized by cross-linking, hence forming a 3-dimensional network structure. This particular structure renders collagen insoluble; it is then brought into soluble form by partial hydrolysis as collagen or collagen hydrolysate.
Collagen hydrolysates as a natural biological cosmetic ingredient are isolated and purified using mild extraction or gentle enzymatic degradation. They are dermatologically compatible and free of all contaminants.
High-molecular collagen is an important moisture retainer and is suitable for all skin types. It has been proven that collagens increase hydration, improve skin feeling and decrease the extent and depth of wrinkles.
Protein hydrolysates or wheat protein hydrolysate due to their film-forming properties, provide additional positive effects by contributing to skin smoothness and softness. They also have a remarkably high capacity for free radical capture.
