Undecided Question

What is the best all natural makeup?

Listen up Ladies, Im on the search for what everyone's opinion is of the make up they are wearing. I have two questions. First off, what is it that make's a makeup truly organic or natural. What are the things in make up that would make me age or cause more harm than good. I tend to like a more natural look, but I struggle with under the eye dark circles because of anemia and the fact that nothing I have tried so far stays on for very long. But and here is the big BUT. I take seriously this whole thing about all the unnecessary chemicals we are putting into our body. I have a friend that sells Shaklee makeup but Im just not sure. I like to try it before I buy the whole line. Can someone help me and give me some advice? WHat is paraben? or talc and is there anything else I need to look out for? Who has tried organic makeup or all natural? Does this mineral make up do what it says? Im 36 and I would say I have good skin. Im a country girl and not a barbie by any means but I need to start taking my skin care more seriously but I dont want to overspend. Is oil of olay full of chemicals? Help me ladies Come on!
