I’ve read through here and other places that duoderm is magic for rips. Ok. The description says it’s a hydrocolloid bandage. What’s the difference between duoderm and other hydrocolloidal bandages? They even make them in nifty little circles now for facial acne. I was thinking it’s perfect, already cut to size, and all I have to do is slap a tape grip over it and DD is ready to go. A company called “welly” makes a whole bunch of different kinds of hydrocolloidal bandages, some even waterproof. Is there a difference? Am I barking up the wrong tree? (I am going barking mad from all these rips DD is getting). Thanks!
