Is photodynamic daylight therapy with Metvix available in the US and if so may I ask where. I have read about it and evidently significantly less pain that the usual regimen of PDT. Also, there were studies that if you did use the blu light - if you did the light immediately after applying the initial cream that makes your skin sensitive - it was also significantly less painful. My dermatologist still waits 1 hour after applying the cream and that is extremely painful. The daylight therapy seems like a good compromise. I was now prescribed the 4% solution of 5-fluor. But I am considering ponying up the very expensive price of the .5% solution brand name Carac. Wonder if you know anything about that as well.
