I thought you meant ointment at first but isn't tagederm that plastic sticky bandage stuff they use in wars?
A couple of people put it of me but it always pealed off.
Tim Hendricks and Valerie put me onto Dr Bronars, just wash it with that and heals fine.

Makes me laugh people leathering them in ointment believing coco butter or some made up tattoo shit will help it heal

I get what you mean but this is

That's odd when I've had it on the tattooer as applied it and said leave it until it falls off and tattoo should be healed, I always have a corner peal off so end up pulling it off and doing the wash process.

It was initially developed for use in in the battlefield, pretty much sticky back plastic that they whack on fresh wounds.

The first time I used it the tattooer said it might not stay stuck as it was a big coverage, and went onto a joint, the second time was a smaller are and close to a joint it started to peal away by the joint so I pealed it off, the third time was a massive area and it was pulling body hair out so I pealed it off, it was that hard to get it off it brought a rash to the surface of the skin. I wouldn't like to think I was putting that on and pealing off regularly. All three of those tattooers told me the same thing, leave it on as long as you can, and it will peal off when the tattoo heals, but obviously bodies move about and it can peal off so leave it as long as you can.
If I told you who they where I'm pretty sure you wouldn't think they'd got mixed up.
Unless we are talking about different stuff and I'm getting mixed up!
Genuinely find the best method is wash it,and keep it out of the sun.

Just had my back outlined off a good friend Nick Mayes, had this Hannya done off him on my front about a month back too
