Yes, parsley -- as in the stuff you use in soups and salads. Parsley contains high concentrations of vitamin C, iron and manganese. It also contains calcium, is a major source of potassium and is a great antioxidant for your skin. All of this helps to produce collagen. Parsley is a big-time player in many of the latest beauty products, but you can make your own beauty mask at home with the herb, a tablespoon of plain yogurt and a bit of cucumber.
