Have been using this US brand for about 5 years. I love it.
She's a bit of a crusader against the nonsense spun in the beauty industry. She stresses the ingredients that have proven published research (and not that paid for by estte Lauder etc) in order to assess products claims. You may (undertsndably) think her stance is undercut by the fact she sells her own line but I'm glad she does as a lot of the products from other companies that she recomends aren't available in the UK.
Anyway here's the link
