Tea Tree Oil

While looking into acne treatments for my daughter I ran across some info that tea tree oil can help reduce acne. I know tea tree oil is a wonderful all-natural mold and mildew killer but have never tried it for anything other than some bathroom cleaning. Has anyone tried tea tree oil for acne? It has anti-fungal and anti-inflammatory properties so I would not be surprised if it did help reduce the appearance of acne breakouts.
