I know Paula harps about jars and anti-oxidants but what about sunscreen ing's? Does it degrade those too? Why would manufacturers use jars of the whole thing was worthless within a short period of time after opening it? I just got to wondering about this after reading another thread here where Paula was misinformed. She is the only one I hear talking about the jars. We all know Vit C needs opaque packaging to remain stable, but I'm talking how she broadly paints the picture that anything in a jar is bad. What do you guys think?
