Just to let others know. After I had a follow up visit to my derm. I told him the problems I was having. He told me that it sounds like I was having an allergic reaction to the Benzol Peroxide in the duac. He switched me to Evoclin - which is a foam that doesn't have the B.P. and still contains the clymid. ingredient. I haven't had any problems since. I still wouldn't give my worst enemy the duac.
