I love Dr. Bronner's peppermint liquid soap! There are other scents, but peppermint is my favorite. I use it nightly to wash my face. It does a great job removing oils and my face feels fresh. I tend to have breakouts when I don't use this soap. Some folks find it pricey, but it is really concentrated so you don't need to use much. Plus you can use it for a lot more than just washing your face. I have washed clothes in it and shampooed my carpet with some.
You can buy it at natural food stores, online at the Dr. Bronner's site http://www.drbronner.com/DBMS/SFNT.htm or at some grocery stores. The site also has a store locator so you can find it locally.
