A lot of us avoid personal-care products that contain parabens, the chemical preservative that has been linked to a whole host of health concerns. The good news is that paraben-free products are easier to find; the bad news is that the shelf life for these items is not as long. One way to help extend and preserve the life of your all-natural moisturizers, shampoos, makeup and other personal products is to refrigerate them. For day-to-day items, there's no need to store them in the fridge since they will be used quickly. But for infrequently used items, keeping them in the fridge will inhibit the growth of bacteria and lengthen the shelf life of the products.
