Barbara, for what it's worth, about half way through radiation, we switched from radioplex to regular Neosporin after every rad treatment...based on the advice of some of the other U of C patients. As soon as he was done with each rad, I'd put vislon burn pads (6) all around his cheeks, face & neck, wrapping in gauze to keep them in place, and he'd take a nap for around an hour. Then I'd slather him in Neosporin. I believe it helped a lot, Vince's skin never did break down, although during the last week, in the crease of his neck, it was paper thin. One point, no matter what you're putting on your husband's skin, be sure it's dry for each rad treatment. Best of luck...you're almost through it, Ana
