Martin told me say, with the aqueous cream it is essentail to put in on very liberally. At least 4 tablespoons full, to try and quantify it. I think this is the only reason he didn't fry, I absolutely smothered his neck every day 2 times a day. before bedtime and after radiation. I didnt wash it off, because it dried during the night and it seems it got absorbed by the skin. Martin insists, don't be afraid to put loads on. The skin became smelly and peeled terrible (moisturised dead skin i suppose), but it wasn't burned or scabby and the skin under was fine (like a baby's bum he just said).
