I havent tried hers, I would be interested to know what anybody thinks of them. I used to use all the Chanels, Clinique etc but they can be too harsh on the skin.
For 100% natural I would say: Liz Earle, Neals Yard. If you were willing to pay the money then REN are excellent but may be similar pricing to Chanel. Green&Spring (also expensive!)
I would not recommend Lush, I am a fan of their products but they are not all natural. I know most of their skincare do still contain Methylparaben and/or Propylparabens. They have promised to make more products 100% natural, some have been changed over during the last few years. Their soaps are now 100% natural. However still much nicer on the skin that Chanel etc, I find. Body Shop is the same, they stock a few natural products am not sure if any are in their skincare.
There is a site I've heard of 'Green People', I havent tried it but heard very good things -it's always winning 'eco' awards. The products are good for sensitive skin plus Natural, organic and very eco, fair trade etc.
