Hi @Bravo I don't know if the vitamin E cream they prescribed changes the radiation but they said carry the tube in my purse to use straight after the radiation and have the tub at home for use four or so times a day. No oils, soaps, deodorants Etc. So presume it's the one they e found to be best for skin after radiation and maybe before as I will be using it before treatment after shower. Like everything else with this BC journey we are led along like horses knowing little of what is ahead of us & without the time (or thought) to ask WHY?
