I used Mepitel. Some ladies here are saying Mepilex, I don't know if these are the same thing.
I did R/T for 25 sessions at LMH in SA. It is a public hospital and they provided Mepitel.
I did not burn at all. I did not use any creams.
The Mepitel was put on at the start, worn 24/7. Patched up and replaced as needed by the Nurses. It was also left on after R/T was completed until it peeled/came off approx 1-2 weeks later.
I was told that the Mepitel provides a protective layer, so that the skin does not get friction from clothes, sheets etc.
It also protects by keeping moisture in.
I did get it wet in the shower, but attempted not to aim the shower directly on the area.
Maybe I was lucky. But I credit Mepitel.
Have you had your planning session? Have Icon given you advice as yet? Do they offer Mepitel?
All the best for your treatment.
