Leaves face clean and clears acne. Glycerin-based tea tree oil and Triclosan to control oil, shine, and breakouts. NONE This soap is fantastic but extremely hard to find. I used it daily for years when younger (I am now 50 with mild adult acne). I used to be able to purchase it at Wal-Mart and Walgreens but the only place I can buy it now is on the Ulta website. Over the years since being unable to purchase it I have spent a fortune on things that don't work from low end pricing to high end. This bar smells great, cleans without drying and keeps your skin from getting oily. It has a fresh lemony smell nothing like tea tree oil. My son has heavy acne on face and back and finally tried the bar....it is slowly but surely clearing it up!! I bought several bars because I am afraid to run out again!
