I'm currently on Calcipotriene aka Dovonex. I've been using it since mid to late January and have seen great results so far. I'm not healed yet, but I feel as though I'm close. I too had a burning sensation and irritation on the lips and corners. I also experienced extra slight peeling around the lips, but after a couple months these side effects subsided and I no longer experience them....If I were you I would definitely try Dovonex again.
