Hi Just,
My grandmother was never without her little blue bottle of Vap-o-Rub. That and she always had rubber bands on her wrist........because I guess you never know when you'll need a rubber band. But we'd never tell Grandma if we weren't feeling great or had a cold..........cuz she's grab us and slap the stinky Vap-O-Rub on us and our friends would make fun of us smelling God-aweful. But she meant well!!
Vap-O is mostly petroleum jelly, like Vasoline.....it's just spiced up with a bit of camphor and mentol. But it also has turpentine oil, eucalyptus oil, and cedar leaf oil, which causes skin irritation for some folks. So I'd suggest that anyone wanting to put it near their stoma start with a single VERY small spot first. It will do a good job of trapping moisture in the skin, so it works for dry skin, but Vasoline does the same thing without the skin irritation issue. But I'm glad it works for you!
Luv.........you can bet it does affect adhesion......it eliminates it. My skin irritation always involves my skin just OUTSIDE the edge of my barrier, so I put Vasoline on sometimes AFTER the barrier is fully applied, and only on the extreme edges of the barrier.
