Collagen is the most important protein in our body. It is a fundamental building block of connective tissue and is found not only in the skin, but also in tendons, joints, ligaments, bones, blood-vessel walls - and even in the cornea in the eye. As it is collagen that determines the firmness of connective tissue, it is also called the body's "filler". Sufficient collagen content is therefore the main requirement for skin to have a firm appearance - and indeed the whole body. But collagen is also vitally important for the health of bones, tendons, joints, ligaments etc.
