I bought the first time patches on Amazon, because I only get in retail with us Waterproofing patch or standard plaster. The peer-reviewed patch I use since x years because they adhere very well, will quickly dry again, once got wet and the skin is not so disgusting white. Waterproofing plasters, especially the individually packaged with fixed dressings, are virtually useless in my opinion. I hurt myself often when tinkering or home improvement, nothing great, but usually can not be ignored. Then I need a Band-Aid, which also holds at least by wetting and mechanical stress one day.
This works with the peer-reviewed, not with the water-resistant.
