They have some great products, although most of the stuff I loved was discontinued years ago.
The products smell quite strong, but they mainly use essential oils and very few synthetic perfumes, so they shouldn't cause thrush unless you're extremely prone to it. The colours are either all natural or around 98% natuiral (I forget which - I worked for them for a whole, but it was a long time ago).
Their facial moisturisers are excellent, and if you ask nicely they'll give you a little sample to try out so you know that you get the right one for you. celestial is superb for very sensitive skin.
Their body scrubs (Buffy, Aqua Mirabilis - there's probably more too, but I only remember those two) are brilliant as well. And Ocean Salt facial scrub is great for those with less sensitive skins and is especially good on people with darker skin.
The hair masks are also worth buying if you have damaged or difficult hair, and the fresh face masks are good also (especially Catastrophe Cosmetic if you have sensitive skin or Love Lettuce for combination skin). If you only use half the pot, you can freeze the rest to use another time if you don't think you'll get through the whole pot before it goes off.
