@pip47 Mepitel is a film that goes on the skin to be irradiated. It affects how the radiation enters the skin (somehow - can't quite remember - by changing the depth, I think). It doesn't make the treatment any less but does protect the skin a lot. I was treated in a public hospital and had to ask for the film. No problem in getting it but it wasn't offered up front. There was a couple of days when I had a slight gap between two pieces. In that short time, I got a dark tan line so I know it did do a lot to protect me. It stayed on all week during treatment and then I could take it off for the weekend and moisturise the area. I had no real problems with my skin except for a red tender spot 3 weeks after treatment finished.
