Hi Stillwater,
My forehead and back are very slow at responding to the Efudex. I am on Day 14 and only a few red spots on those two areas. My chest, nose, chin, and face responded much quicker. My doctor added Retin A to my treatment, which I apply before the Efudex. I am also amazed how slow those areas are, too. I have had squamous cell cancers removed from both areas so know there is sun damage. I guess only time will tell! Good luck!
