What products work best for skin during radiation?

I went through 33 days of radiation on my right breast. I used Udderly Smooth body cream 3 times a day throughout treatment, and the radiation technicians were amazed by the results. At the end, my radiation oncologist could barely see a color difference. The only discomfort I remember having is one hot August day when I went a little too rough with the washcloth in the shower underneath the breast and damaged the tender skin. It cleared up in a few days with nothing more than a little TLC. I wholeheartedly recommend this product. You can find it on Amazon, Dollar Tree, and many farm supply stores. (Yeah, I know) But it truly works and is inexpensive.
