80-90% of collagen in the human body consists of types I, II, and III collagen, although at least 16 different forms of the protein are known. Gram for gram, type I collagen is stronger than steel! Collagen used for medical purposes need not be human collagen. The protein may also be obtained from pigs, cattle, and sheep. Collagen may be applied to wounds to serve as a scaffold on which new cells can form, thus improving healing. Because collagen is such a large protein, it is not absorbed through the skin.
