Free Style free patch adhesive

Good I would like to consult them, I have been free of the free patch and I cover it with Fixomull, as they indicated to protect it and prevent it from taking off, the case is that in certain places of the skin it produces a lot of itching and imaging redness that will be some kind ofallergy or reaction.
You could tell me if there is any other type of adhesive that does not produce allergies and be able to cover the patch.

Thanks a greeting

Cover Freestyle Bathroom patch
Hello everyone,

Let's see if you can give me a hand, I would like to bathe on the beach and I don't know how to cover the patch, I have been told a piece of neoprene, but I can't find any anywhere....

OK thanks
