I use DHC. Here's the link:

I swear by their products! I use to have horrible skin until I found them (via some womens magazine)! I use their foaming facial cleanser and their acerola gel. It's kind of expensive but well worth it. They're based out of Japan but have a store in San Francisco. I think you can contact them and ask for free samples. Not sure. I know you can get up to 4 free samples with every order you put in.

Good luck!
