I've used Gaia in the past. I like the big bottle of moisturiser (still have heaps left from 3 years ago!) as a barrier cream now for face painting
Anyhoo, I have only been impressed by Moo Goo for product goodness and absolute value for money.
Natural Instincts seems to be quite diluted in base product more than 'active ingredient' and I never trusted it enough to buy it.
Moo Goo all the way for me
We're a moo goo family too. We use their shampoos, creams and soaps. Their products seem quite expesive, but they do last a lot longer, so it works out okay. I bought a tub on their msn cream, as a nappy cream, but found it to be too thin, but it does work really well on rashes etc.
