When Collagen containing products first entered the market there were great expectations that they would perform very well in the attempt to boost collagen levels in the skin however the results were disappointing. The reason is collagen is too large to penetrate through the skin. Hydrolysed collagen (smaller but still too big) was also developed however it too does not aborb however it does offer some limited hydration benefits.
Recently a new generation collagen fragment has been developed. It is a remastered concept of collagen for a new collagen era. Col Frag (Nicotiana Benthamiana Hexapeptide-40 sh-Polypeptide-47) is a collagen fragment small enough to be able to absorb through the skin. This is a type 1 fully functional Collagen fragment identical to human collagen type 1. Studies show its ability to effectively reduce the appearance of wrinkle length and depth.
