I have suffered with angular cheilitis for many years. I have tried many things including, antibacterial cream, cortisone cream, fungal cream, tea tree oil, oregano oil, hydrogen peroxide and more. I had some success with tea tree at keeping the sores from getting larger but nothing has helped to diminish them until now. My angular cheilitis was a pretty severe case with a raise "sore" at the corner of my lips that was at least the size of a dime, and then raised up somewhere between 5-7 millimeters. The condition has really hurt my self esteem. Thankfully I finally found a way to rid myself of angular cheilitis. I made a paste of castor oil and baking soda and applied it over night. After just one application my angular cheilitis was reduced by half, several more and it now almost completely gone! This remedy has been easy, cheap, and it's the only thing I have ever found to be effective. Just mix some castor oil and baking soda until it makes a thick heavy paste and leave on over night. It will burn some but it really really really helps!
