Hi,
I used 0.5% Carac for four weeks just on my forehead for Actinic Keratosis. I did not use Triamcinolone cream. I did use Vaseline and Aquaphor to help control dryness and itching, after asking my dermatologist if this would be OK. Two weeks seems like a pretty short course of treatment. The studies show that rates of success are higher with four weeks of treatment, but you didn't mention what strength Carac you will be using, or what you are treating, so maybe that makes a difference.
The Carac seems to have worked for me. I had very diffuse actinic keratosis on my forehead and it all seems to be gone now. The redness is still going away, but is has faded quite a bit and I believe it will go away completely over time. It has been about two months since I completed my treatment. So far I believe it was probably worth it. I did a lot of research on the various alternatives before I went with the Carac.
Good luck.
