Definitely ask about the Mepitel (it does come under different brand names but they'll know what you're talking about). Some places offer it, some don't, some have it but only use it when asked. There's also different ideas about how it will be used. For my treatment, it was put on beforehand on the Monday, patched during the week if necessary, and I took it off when I got home on Friday. During the weekend I was free to shower and use moisturiser (my go to was Moo Goo). My skin held up beautifully - about 3 weeks after treatment ended, I go a small tender patch on my side. I believe the StrataXRT cream is excellent but I think you have to supply it yourself at most places and it is quite expensive.
