Personally, I really like Origins Perfect World- nothing I have sampled is the same, but you do need the skin gurardian and the mosituriser to really get the benefits I think. I can't normally afford it, but they do reduce their gift-sets ocassionally.
I love Lush too, but think its more the whole culture rather then just the products! But I do really rate the fact they are natural or as natural as they can be- I worry about what I put on my skin and could do without the constant niggle at the back of my head saying "I wouldn't do that if I were you..." I just get worried when I think about all the new illnesses and allergies that we have now that didn't exist 150 years ago when man-made products were just not so well used. It does make me wonder.
Aveda also make natural based products, but I've never tried any of thier skin care stuff, only the hair care.
But that still doesn't stop me buying them- only I do try to stick to a more plant-based natural formula wherever possible, if it can do a similar job, I'm sold!
