Effectiveness

• While medical experts acknowledge the importance of protein in the diet, many note there is no proof that ingesting collagen results in smoother skin. According to Ray Sahelian, M.D., research does not indicate that consuming collagen can treat medical conditions or retard skin aging.
  
  

Risks

• While there are no known medical risks associated with consuming collagen, it can be an expensive investment for a product that has no proven benefit to the skin.
