This needs to be addressed because by trying to prevent, you'll just drive it underground and it could get a lot worse. She's Obsessive Compulsive Disorder (OCD), which means if she starts getting compulsive with this (if she isn't already) then it could get really unhealthy.
I'd make sure husband is on board, she IS his daughter, and both of you take her to the doctor for a thorough physical and a solid talk about why she is doing this, as well as what is really going on.
You have to do something solid to really deal with this as the serious problem it is.
Something else is going on underneath this. Until you can find out what it is and help her deal with it, the underlying distress is going to continue, and she will break out somewhere as a way of trying to cope.
Don't be angry with her - something is really wrong and she doesn't fully understand what or why yet, let alone what to do.
