This isn't my area of expertise, but I think it's probably "green ear"Archived Message

It's a known Barbie problem. I don't know if zit medicine will help for that, if you've had it on that long, I doubt it. You can Google "green ear" & find lots of solutions. I always use this stuff http://www.twinpines.com/remove-zit for stains. It says it's good for green ear, but I've never used it for that so I can't verify.
