Collagen is found in the connective tissue of our skin, teeth, bones, organs, and cartilage.Collagen keeps our skin firm and resilient, protecting it from wrinkling. The role of vitamin C in the production of collagen is to interact with amino acids within collagen cells.It adds hydrogen and oxygen to those amino acids, so that they may do their part in collagen production. If you donât get the proper amount of vitamin C, collagen production will slow.ollagen keeps our skin firm and resilient, protecting it from wrinkling.
