@lindagi Many people have a variety of responses to using this treatment. It seems a lot depends on how severe or problematic the area is that is being treated. I know for me that is a good indicator of how things might turn out. If there is more for the fluorouracil to "battle" the more pronounced or length of time for the redness/scabbing. And of course, in my situation, I have sensitive skin anyways, so that can play havoc.

Those areas you described tend to get the hidden spots, being in a sun-kissed area and more prominent. Have you tried some rich Vitamin E cream [just a bit] to help heal everything up, now? Have you checked with your doctor for follow-up?
