I have always had clear skin, until I turned 25. When I was 25 my sister gave me some samples of duac, I used it when I saw something forming, just a dap on the spot over night, by morning, that spot was usually clear, for sure by the next day!! It was great! Then, two years later, I ran out of the duac samples. Then settled for Benzolcine(SP?) RX from the doctor, that stuff didn't work at all even though it has EXACTLY the same ingredients!?!?! The Benzolcine dried out my face bad and I broke out soooo bad too. So, I went to the doctor and only settled for the Duac gel RX. And I will never try something else again. This stuff is perfect for me. Again, as soon as I feel or see alittle something, I dap it before bed time, and it's usually gone by morning. After getting back to Duac, I had to use it morning and night. But, after a few weeks, now just at night again, like before. I do have sensitive skin too, but for some reason, duac doesn't dry it out at all.
