I just finished radiation and chemo. I used CeraVe during and Aquaphor after. Right after I stopped radiation the burns were very bad. I under that's common. That's when I switched to Aquaphor. My nurse also gave me some Vaseline soaked gauze wraps that were wonderful. Put those on over the Aquaphor. I wrapped a piece of cut off t shirt fabric around my neck to keep it all in place and it worked to heal quickly.
