After 6 months of use of Epiduo, the redness is still on/off. It will work great for a month's time with no redness at all, then boom... Redness and spots all over the area applied. Do you think this is due to weather changes?

I also use some cream containing a bit hydrocortison for some eczema on my arms. Could this be a part of the problem?

I really don't want to stop using Epiduo since it has made great results.
