I've been using it for about 5 years. Its fantastic. You will need to consult with a Hauschka specialist--usually the stores that sell it can help you, because there are different kinds of products for different kinds of skin. They can give you samples to see what your skin needs, and then once you've adjusted, you will be able to get a routine down.
I use morning and night:
cleansing milk (awesome for removing makeup)
clarifying toner (pat it on, don't wipe)
moisturizing day cream
in the shower, I use cleansing cream before the morning treatment.
my skin looks so much better since I've been using it.
It costs a lot, but IMHO its totally worth it.
Another good way to learn about it is to get a facial from a Dr. Hauschka trained beautician.
You can call Hauschka and they can tell you who is in your area.
I had it at Auberge du Solei in Napa, but I now go to Orange Spa in SF.
