Organic fruit and vegetables are now readily available, but organic beauty products aren't so easy to track down.
The trick is knowing where to shop and what you're looking for, especially when it comes to makeup.
"In order to be certified organic a product needs to be 95 of ingredients need to be approved non-organic, which means they must be nontoxic to humans and the environment."
This means you're looking for products which are free from formaldehyde and formaldehyde-releasing preservatives, parabens which are "small enough to get into the skin," and phthalates "which mimic oestrogen in the body."
So, where can such beauty buys be found?
Marrone's brand is a good place to start - her brilliant Organic Glam range includes everything from natural nail polish to eyeliner.
